1. GHK-Cu Peptides
The GHK-Cu peptides are copper based peptides that have been shown to increase the rate of root formation, improve the quality of roots, and enhance the growth of the plant. These peptides are derived from the GHK (Glu-His-Lys) protein family, which is present in many organisms including humans. In addition, these peptides have been shown to inhibit the activity of human Cu/Zn superoxide dismutase (SOD), which is responsible for catalyzing the conversion of superoxide radicals to hydrogen peroxide. Superoxide radicals are produced during respiration and are toxic to cells. By inhibiting SOD, GHK-Cu peptide increases the amount of free oxygen around the plant, thus increasing its tolerance to oxidative stress.
2. Copper
Copper is a trace mineral that is necessary for proper plant function. It is involved in numerous processes including photosynthesis, respiration, and hormone production. Copper is also known to play a role in the synthesis of chlorophyll, which is necessary for photosynthesis. Copper is also a cofactor for enzymes that help break down lignin, a complex polymer that makes up the majority of woody biomass. As a result, copper is often added to composts and soils to increase their efficiency at breaking down lignin.
3. Zinc
Zinc is a trace mineral that helps regulate cellular division and differentiation. It is also involved in the synthesis of DNA and RNA, which are the building blocks of genetic information. Zinc is also important for the regulation of enzyme activity, which is necessary for metabolic reactions.
4. Lignin
Lignin is a complex polymer that is primarily composed of carbon, oxygen, hydrogen, and sulfur. It is the primary structural material of plants and provides rigidity and structure to the plant. Lignin is also a major contributor to the brown color of wood. Lignin is broken down by fungi and bacteria, which is why it is commonly added to composts and soil to make them more effective at breaking down organic matter.
5. Glucose
Glucose is a simple sugar that is found in fruits, vegetables, and cereals. It is the preferred fuel source for the body and brain. Glucose is also utilized by plants as a source of energy. When glucose is not available to the plant, it begins to produce starch instead.
6. Starch
Starch is a carbohydrate that is stored in the plant’s seeds, tubers, stems, and roots. It is the primary storage form of carbohydrates in plants. Starch is also the primary form of carbohydrate in grains and legumes.
7. Sucrose
Sucrose is a disaccharide that is formed from two monosaccharides, glucose and fructose. Sucrose is the predominant form of carbohydrate in plants and is the primary form of carbohydrate consumed by animals.

-
First time using GHK-Cu. It’s a powder, so you have to reconstitute it yourself. I bought a separate bacteriostatic water bottle from a medical supplier. Took a few tries to get the mixing right – you really need to be careful with the math. After about three weeks I started noticing my skin looked more plump and less dull. Downsides: it can sting a little if you put too much, and it smells slightly metallic. Not a dealbreaker. I’d recommend starting with a low dose. No complaints about the product itself, just be ready for some trial and error.
-
It’s a solid product for the price. I reconstitute with bacteriostatic water and apply topically. Takes about three weeks to see any effect—my skin looks a bit plumper and a small scar seems lighter. Only reason I’m not giving five stars is the vial is tiny and the powder can stick to the stopper. Otherwise, no complaints. I bought from The Peptide Lab and the order was spot on.
-
Decent product for the price. I reconstituted with bacteriostatic water and started with a low dose. I noticed some redness the first couple days—probably because I went too strong. Once I backed off, my skin started looking more even. The powder seemed pure, no clumps. Only complaint: the vial is tiny, hard to get the last bit out. But that’s kind of standard. Would recommend if you’re patient with titration.
-
I’ve been making my own peptide serums for a couple years, and GHK-Cu is one of my staples. This 20 mg vial from The Peptide Lab is a great value. It’s pure, no clumping, dissolves clear. I use it at 1% concentration in a DIY serum with niacinamide and it’s done wonders for my skin texture and redness. Shipping was quick, packaging was discreet. Only minor thing: the vial is a bit small, so I wish they included a tiny spatula for scooping, but that’s really nitpicking. Recommended for anyone who already knows how to handle peptides.
-
I started using this GHK-Cu about a month ago in my nightly serum mix. I’m in my late 30s and have been dealing with some sun damage and fine lines. This peptide seems to be making a real difference—my skin looks plumper and the redness around my nose has calmed down. I mix it with distilled water and a little hyaluronic acid. The powder dissolves easily. Shipping from The Peptide Lab was quick and the vial was well sealed. Only minor thing: I wish the vial were a bit bigger so I didn’t have to reorder as often, but for the price it’s fine. Will definitely repurchase.
-
I’ve been using this copper peptide for about six weeks now. I mix it with a little distilled water and add a few drops to my nightly moisturizer. The change is subtle but real – my fine lines around the eyes look softer, and a few old acne scars have faded a lot. It did cause a bit of redness the first week, but I started using less and that went away. Packaging was a standard small vial with a screw cap, no issues. The Peptide Lab shipped fast and the vial was sealed well. I’m already ordering my second one.
-
I’ve been using this GHK-Cu for about six weeks now, mixing it into my nightly serum. My skin texture has definitely improved—less redness and the fine lines around my eyes are noticeably softer. I was a little nervous about reconstituting peptides at first, but the instructions on The Peptide Lab’s site were clear. Shipping was fast and the vials came well-packed with ice packs. This is my second bottle and I’ll keep ordering.
-
I’m using this in a small cell culture experiment looking at wound healing markers. The purity seems high—our assays are clean and reproducible. We’ve ordered from The Peptide Lab before and their QC is consistent. The 20 mg size is convenient for multiple runs. If you’re in research, this is a good reliable source. Would recommend.
-
I’ve tried a few different brands of GHK-Cu and this one from The Peptide Lab is by far the most consistent. I reconstitute with bacteriostatic water and use it in my microneedling sessions. My skin looks brighter and my pores are smaller after about 6 weekly treatments. No stinging or irritation. The powder is a nice light blue, which tells me it’s pure. I’ve been using peptides for years—this is my go-to now. Only wish they offered a larger size like 50mg, but 20mg is convenient for testing.
-
I use this for DIY skincare. The copper peptide itself seems high quality—no clumps, dissolves clear. I’ve been applying it topically and noticed my acne scars fading a bit after three weeks. Only reason I’m not giving five stars is because when I accidentally got a tiny drop near my lips, it tasted awful. That’s not really the product’s fault though. Just be careful with application. I bought from The Peptide Lab and the packaging was professional, ice pack included. Would recommend.
-
I tried this peptide for hair regrowth after reading some forums. Mixed it into a spray with distilled water. Been using it for 6 weeks now – maybe a little more density around the temples, but nothing dramatic. The product itself seems fine, no contamination, and the vial arrived intact. But I expected more based on the hype. Will finish the vial and see. Might try a different concentration next time. The Peptide Lab customer service was helpful though.
-
I know GHK-Cu is supposed to be great for skin, but after two weeks of using it I didn’t see any difference. Maybe I needed more time, but I was hoping for something faster. The powder reconstituted fine and no irritation. Just didn’t get results. Might try a different brand next time. Order from The Peptide Lab was fine, no complaints about shipping.
-
I’m a researcher in a small biotech lab and we use GHK-Cu for cell culture experiments. This batch seems consistent and pure. The solubility in sterile water is fine. Just be aware that if you’re using it for topical applications, you need to buffer it properly – too high a concentration can sting. Ordered from The Peptide Lab and it came well-packed with ice packs. Rating 4 because the price per mg is a bit high compared to larger quantities, but for a short trial it’s fine.
-
I’ve been using copper peptides on and off for years, mostly from cosmetic serums. Decided to try this raw powder version to save money. Mixed it myself—kind of fiddly with the measuring. Results are subtle; my skin feels smoother but no major anti-aging magic. Might be better for people with more sun damage. Shipping was fine. Probably won’t repurchase, but it’s not bad.
-
First time using copper peptides. I bought this one because the reviews were solid. The powder is fine and dissolves okay, but you really have to shake it well. I accidentally used too much water once and it seemed less effective. Should have followed the instructions more carefully. My skin looks brighter after two weeks, and a small cut healed faster. I’d give it 5 stars if the mixing was more straightforward. Packaging from The Peptide Lab was discreet and on time.
-
I do microneedling at home every 6 weeks and started adding GHK-Cu right after the treatment. The healing time dropped from 4 days to about 2. My skin looks glowy and no breakouts. This is my third purchase from The Peptide Lab – consistent quality. I reconstitute with bacteriostatic water and keep it in the fridge. The 20mg size lasts me about 3 weeks. Highly recommended if you’re into advanced skincare routines.
-
I’m a nurse and use copper peptides on small cuts and surgical scars. This one works well. I mix it into a sterile saline solution and apply with a cotton pad. It definitely speeds up the healing process. The 20mg vial is enough for several applications. One thing: the stopper is a bit stiff, so be careful when inserting the needle. Other than that, quality is solid. I ordered from The Peptide Lab and it arrived in two days, well insulated. Recommended for anyone into regenerative skincare.
-
I’ve been using this GHK-Cu for about three weeks now, mixing it into my nightly serum. I was skeptical at first because I’ve tried so many copper peptide products that did nothing. But this one? My skin looks brighter, and a few fine lines around my eyes seem softer. The powder dissolves clear and doesn’t foam up weirdly. The Peptide Lab shipped it fast, and the vial was well sealed. I’ll definitely order again.
-
I’ve been making my own copper peptide spray for my face and neck. One bottle lasts me over a month. I like that it dissolves easily. My skin tone looks more even and breakouts heal faster. Only downside: the vial is glass and I wish it came with a tiny spatula to get all the powder out. But that’s minor. Overall happy with this purchase.
-
I wanted to love this because everyone raves about copper peptides. I’ve been using it for a month, mixed into a simple hyaluronic acid serum. The first week my skin looked brighter, but then I started getting tiny red bumps around my jawline. I backed off to every other day and that helped a little, but the irritation never fully stopped. Maybe my skin is just sensitive to it. The powder quality seems fine – dissolves easily. I’ll finish the vial but probably won’t repurchase. Not a bad product, just not for me.
-
I bought this to help with a surgical scar on my arm. Used it topically (mixed with a basic moisturizer) twice a day for a month. The scar is noticeably lighter and flatter. I didn’t expect much honestly, but I’m impressed. The Peptide Lab sent it quickly with an ice pack even though it wasn’t super hot outside. No issues with the product itself. Will repurchase.
-
I’ve been using GHK-Cu for about three months now to help with post-inflammatory hyperpigmentation and some fine lines. The results are subtle but real. My skin looks plumper, and a stubborn scar from a burn has faded significantly. I reconstitute with bacteriostatic water and apply topically as part of my nightly routine. It stings a little at first but goes away quickly. Definitely worth the patience.
-
I’ve been using this for about two weeks now, mixing it with a basic moisturizer. I haven’t seen dramatic changes yet. My skin does feel slightly smoother, but no noticeable reduction in fine lines. I know copper peptides can take longer, so I’ll keep going. The powder itself seems fine, no weird smell. I just expected a bit more initial glow. Might work better for others with more damaged skin. For now, it’s okay. The Peptide Lab’s shipping was fast though, no complaints there.
-
I read that GHK-Cu can help with hair growth and nail strength, so I decided to try it orally—mixing the powder into my morning smoothie. Tastes slightly metallic but not unbearable. Within 3 weeks, my nails stopped splitting and started growing faster. My hair, which had been thinning due to stress, has new baby hairs around my temples. I’m amazed. I use 10mg per day (half a vial) and cycle 5 days on, 2 off. The only hassle is weighing the powder accurately; I use a micro scale. Wish they’d provide a scoop. But the results speak for themselves. Will definitely buy again.
-
I’ve tried a couple different copper peptide sources before, and this one from The Peptide Lab seems legit. Reason I’m giving four stars instead of five is that it stings for a few minutes after I apply it—nothing crazy, just a mild tingle. Might be my skin sensitivity, so not a dealbreaker. The results are there: better texture, less redness, and my pores look smaller after a month of use. Reconstitution was straightforward. Packaging was decent, no leaks. Would recommend if you’re okay with a little initial irritation.
-
I’ve been using this GHK-Cu 20mg for about six weeks now and the difference in my skin is incredible. I’m in my late 40s and was starting to see significant fine lines and loss of elasticity. I mix the powder with a few drops of distilled water and then add it to my regular serum. The first week or two I noticed a mild tingling, but that faded quickly. By week three, my skin looked plumper and brighter. Now at week six, my nasolabial folds are visibly softer and my complexion is more even. I’ve tried other copper peptides before but this concentration is more potent. You only need a tiny amount—I reconstitute the 20mg and it lasts me over a month. Just make sure to store it in the fridge after mixing. Highly recommend for anyone serious about anti-aging.
-
Been using this GHK-Cu for about three weeks now, mixing it into my nighttime serum. The powder dissolves cleanly with bacteriostatic water, no clumping. I was a little worried about oxidation because copper peptides can be finicky, but this batch stayed clear in the fridge. Skin feels firmer and the fine lines around my eyes are definitely softer. Not a miracle worker, but noticeable improvement. I ordered from The Peptide Lab and the shipping was fast—packed with an ice pack even though it was warm out. Only downside: the vial is tiny, but 20 mg goes a long way if you’re careful with dosing. Would buy again.
-
Got the 20mg GHK-Cu for DIY anti-aging injections. The quality seems good—no clumping, dissolves clear with bac water. However, the vial is a bit tricky to handle; the stopper feels stiff, and the powder tends to stick to the glass. I’d recommend using a bigger syringe to reconstitute. On the plus side, after a month of subq injections (2mg every other day), my skin elasticity has improved, and a couple of stubborn acne scars are fading. I’m downrating one star because the product literature is minimal—no clear storage instructions or pH info. I had to research online. Still, it does what it’s supposed to.
-
I’ve ordered GHK-Cu from several suppliers, and this 20mg vial is consistently good. The powder is a light blue, fine and fluffy, and it mixes cleanly with sterile water. I use it for microneedling every 10 days—diluting with a peptide mix. The results are subtle but cumulative: my pores look smaller and my skin has a nice glow. I appreciate that the batch was tested (the COA was included). Shipping took only 4 days, well-packed with a cold pack though not required. Only reason for 4 stars is that the vial is only 2ml size, making mixing a bit fiddly. Otherwise, solid product.
-
I’ve been using GHK-Cu for about 6 weeks now, reconstituting with bacteriostatic water and applying topically as part of my nightly routine. The first few days I noticed some minor tingling, but that faded quickly. Around week 3, I started seeing real improvements—my fine lines around the eyes are noticeably softer, and my skin tone is more even. I mix it with a simple hyaluronic acid serum, and it absorbs without any stickiness. A little goes a long way; one 20mg vial lasts me nearly a month. Only downside is the price, but considering the results, it’s worth it. I’m already planning to repurchase.
-
I’ve been using this GHK-Cu for about a month now, mixing it with my regular serum. My fine lines around the eyes are definitely less noticeable, and my skin just looks more plump and healthy. I read that copper peptides help with collagen production, and I think it’s working. The powder dissolves easily, no clumps. I bought it from The Peptide Lab and shipping was fast. Only downside is the vial is small, but for 20mg it’s expected. Will repurchase.
-
I’ve tried a few copper peptide brands, and this 20 mg vial is consistent. I use it for injection to help with tendon recovery from gym injuries. No irritation, dissolves easily, and the price per mg is reasonable. Only reason I’m giving 4 stars instead of 5 is that the stopper is a bit tough to puncture cleanly. But overall, effective product.
-
I wanted to love this copper peptide because I’ve heard so many good things. I used it topically in a DIY serum (mixed with distilled water and a preservative). For the first week, my skin looked plump and hydrated. Then I started getting small red bumps around my jawline. I lowered the concentration from 2% to 1%, and the bumps reduced but didn’t disappear. I think my skin is just sensitive to copper. The product itself seems pure and dissolves easily, but I can’t justify continuing when it causes breakouts. Maybe it’s better for injection? I’ll stick with other peptides. No complaints about the shipping or packaging though.
-
I started using this copper peptide hoping it would help with some stubborn acne scars and overall texture. Initially I was too aggressive—I used the full 20mg reconstituted with just 1ml of water, and my skin got red and irritated. I backed off and diluted it further (used 2ml instead) and started applying every other night. That made all the difference. After a month of consistent use, I can see the scars are less noticeable and my skin feels smoother. It’s not a miracle cure, but it’s definitely helping. The only downside is the product is very concentrated, so if you’re new to copper peptides, read up on proper dilution ratios. I’d give it 5 stars if it came with clearer instructions, but for the price and quality, it’s still a solid buy. I’ll keep using it.

I read that GHK-Cu can help with hair growth and nail strength, so I decided to try it orally—mixing the powder into my morning smoothie. Tastes slightly metallic but not unbearable. Within 3 weeks, my nails stopped splitting and started growing faster. My hair, which had been thinning due to stress, has new baby hairs around my temples. I’m amazed. I use 10mg per day (half a vial) and cycle 5 days on, 2 off. The only hassle is weighing the powder accurately; I use a micro scale. Wish they’d provide a scoop. But the results speak for themselves. Will definitely buy again.

I’ve tried a couple different copper peptide sources before, and this one from The Peptide Lab seems legit. Reason I’m giving four stars instead of five is that it stings for a few minutes after I apply it—nothing crazy, just a mild tingle. Might be my skin sensitivity, so not a dealbreaker. The results are there: better texture, less redness, and my pores look smaller after a month of use. Reconstitution was straightforward. Packaging was decent, no leaks. Would recommend if you’re okay with a little initial irritation.

I’ve been using this GHK-Cu 20mg for about six weeks now and the difference in my skin is incredible. I’m in my late 40s and was starting to see significant fine lines and loss of elasticity. I mix the powder with a few drops of distilled water and then add it to my regular serum. The first week or two I noticed a mild tingling, but that faded quickly. By week three, my skin looked plumper and brighter. Now at week six, my nasolabial folds are visibly softer and my complexion is more even. I’ve tried other copper peptides before but this concentration is more potent. You only need a tiny amount—I reconstitute the 20mg and it lasts me over a month. Just make sure to store it in the fridge after mixing. Highly recommend for anyone serious about anti-aging.

Been using this GHK-Cu for about three weeks now, mixing it into my nighttime serum. The powder dissolves cleanly with bacteriostatic water, no clumping. I was a little worried about oxidation because copper peptides can be finicky, but this batch stayed clear in the fridge. Skin feels firmer and the fine lines around my eyes are definitely softer. Not a miracle worker, but noticeable improvement. I ordered from The Peptide Lab and the shipping was fast—packed with an ice pack even though it was warm out. Only downside: the vial is tiny, but 20 mg goes a long way if you’re careful with dosing. Would buy again.

Got the 20mg GHK-Cu for DIY anti-aging injections. The quality seems good—no clumping, dissolves clear with bac water. However, the vial is a bit tricky to handle; the stopper feels stiff, and the powder tends to stick to the glass. I’d recommend using a bigger syringe to reconstitute. On the plus side, after a month of subq injections (2mg every other day), my skin elasticity has improved, and a couple of stubborn acne scars are fading. I’m downrating one star because the product literature is minimal—no clear storage instructions or pH info. I had to research online. Still, it does what it’s supposed to.

I’ve ordered GHK-Cu from several suppliers, and this 20mg vial is consistently good. The powder is a light blue, fine and fluffy, and it mixes cleanly with sterile water. I use it for microneedling every 10 days—diluting with a peptide mix. The results are subtle but cumulative: my pores look smaller and my skin has a nice glow. I appreciate that the batch was tested (the COA was included). Shipping took only 4 days, well-packed with a cold pack though not required. Only reason for 4 stars is that the vial is only 2ml size, making mixing a bit fiddly. Otherwise, solid product.

I’ve been using GHK-Cu for about 6 weeks now, reconstituting with bacteriostatic water and applying topically as part of my nightly routine. The first few days I noticed some minor tingling, but that faded quickly. Around week 3, I started seeing real improvements—my fine lines around the eyes are noticeably softer, and my skin tone is more even. I mix it with a simple hyaluronic acid serum, and it absorbs without any stickiness. A little goes a long way; one 20mg vial lasts me nearly a month. Only downside is the price, but considering the results, it’s worth it. I’m already planning to repurchase.

I’ve been using this GHK-Cu for about a month now, mixing it with my regular serum. My fine lines around the eyes are definitely less noticeable, and my skin just looks more plump and healthy. I read that copper peptides help with collagen production, and I think it’s working. The powder dissolves easily, no clumps. I bought it from The Peptide Lab and shipping was fast. Only downside is the vial is small, but for 20mg it’s expected. Will repurchase.

I’ve tried a few copper peptide brands, and this 20 mg vial is consistent. I use it for injection to help with tendon recovery from gym injuries. No irritation, dissolves easily, and the price per mg is reasonable. Only reason I’m giving 4 stars instead of 5 is that the stopper is a bit tough to puncture cleanly. But overall, effective product.

I wanted to love this copper peptide because I’ve heard so many good things. I used it topically in a DIY serum (mixed with distilled water and a preservative). For the first week, my skin looked plump and hydrated. Then I started getting small red bumps around my jawline. I lowered the concentration from 2% to 1%, and the bumps reduced but didn’t disappear. I think my skin is just sensitive to copper. The product itself seems pure and dissolves easily, but I can’t justify continuing when it causes breakouts. Maybe it’s better for injection? I’ll stick with other peptides. No complaints about the shipping or packaging though.

I started using this copper peptide hoping it would help with some stubborn acne scars and overall texture. Initially I was too aggressive—I used the full 20mg reconstituted with just 1ml of water, and my skin got red and irritated. I backed off and diluted it further (used 2ml instead) and started applying every other night. That made all the difference. After a month of consistent use, I can see the scars are less noticeable and my skin feels smoother. It’s not a miracle cure, but it’s definitely helping. The only downside is the product is very concentrated, so if you’re new to copper peptides, read up on proper dilution ratios. I’d give it 5 stars if it came with clearer instructions, but for the price and quality, it’s still a solid buy. I’ll keep using it.
