My skin looks firmer, and the fine lines seem less noticeable. Had a little tingling at first, but nothing too bad. The price was reasonable for a small order, and delivery was quick. I’d order again.

Our research group ordered the GHK-Cu serum in bulk for a study looking at how copper peptides affect extracellular matrix remodeling. The bulk pricing worked well for the quantity we needed, and the COAs consistently reported purity above 99% by HPLC across the batches we received. Everything arrived within two days, and the plain outer packaging was convenient for our shared lab receiving area. Customer service was also helpful in answering our questions/concerns. The serum performed as expected in our initial collagen and MMP tests. Generally, we’ve had a positive experience and would consider ordering from them again for future research.

GHK-Cu serum with HPLC-verified purity. Arrived in just two days. Great for research.

I’m using the GHK-Cu serum personally rather than for research, and I chose it specifically for skin firmness and texture rather than general anti-aging. After a few weeks, my skin seemed firmer, and the fine lines around my mouth looked a little less noticeable. I also tried it around my eyebrows and noticed some improvement in fullness, although that took longer to see. I experienced some mild tingling and occasional redness at first, but those were the main issues I noticed. The COA listed 99.8% purity by HPLC, which gave me more confidence in my purchase. Shipping took just one day (delivered the next day), the packaging was plain and discreet, and the price for a single bottle was reasonable. Overall, I’ve been pleased with the experience so far.

Our lab purchased the GHK-Cu serum for a fibroblast culture study focused on collagen synthesis and MMP/TIMP regulation. According to the lot-specific COA supplied with the shipment, the product had a reported HPLC purity of 99.82%, an intact copper-peptide complex, and a copper content of 1%, meeting our stated incoming specifications. The serum has a clear, light-blue appearance and spread evenly during our ex vivo skin explant testing, with no visible signs of precipitation. The order arrived within two days and their bulk pricing was more competitive than other options we considered.Customer support was also prompt in providing the complete chromatogram for our quality assurance records. Overall, the product’s stated characteristics were consistent with the published mechanistic literature on GHK-Cu and its potential regulatory effects on MMP and TIMP activity. A solid option for research applications.

Received my order within two days. The COA listed 99.82% purity, and my skin already feels smoother and softer.
Gregory W. | Laval, Quebec, Canada | ✔ Verified Buyer –
I ordered 10 bottles for my personal use. I applied the serum twice daily on my face and also worked it into my eyebrows and hairline. The most noticeable change was skin texture—finer lines around my eyes softened, and my skin felt firmer. I also saw some improvement in eyebrow thickness, which lines up with the published 12-week split-face trial data. I did get some mild redness and tingling at first, especially on my cheeks, but it settled after the first week or so. The COA in the box showed >99% purity by HPLC. Will order again.

One of the serum bottles arrived cracked, and some of the contents had leaked during shipping. I sent customer service a photo of the damaged bottle and packaging, and they arranged a replacement that same day without any hassle. The new bottle arrived within two days, and its lot-specific COA reported 99.82% purity by HPLC. I appreciated how quickly and smoothly the issue was handled. Good customer service makes a difference when ordering lab supplies, and this experience left us confident about ordering from Pure Peptides Hub again for our dermal fibroblast research.

My skin started looking smoother after a few weeks. I noticed a little tingling at first, but it went away. Delivery was quick, and the packaging was discreet. Pretty happy with my order overall.
Dr. Jerome Hale | Fort Worth, Texas, USA | ✔ Verified Buyer –
We decided to add some peptide pen tips and BAC water to our GHK-Cu serum order, which brought the total over $200 and qualified us for free shipping. Everything arrived within two days, and the packaging was discreet. The COA included in the package listed 99.8% purity by HPLC, consistent with the batch documentation. We were also pleasantly surprised by the quality of the accessories for the price. Overall, it’s been a really good experience so far. The ordering process was easy, everything arrived as expected, and the serum has been performing well in our collagen synthesis assays. We’d happily consider ordering again.

One of the serum bottles arrived with a cracked pump and some leakage, which was disappointing. I emailed customer service a photo of the damage, and they issued a full refund within two business days without asking me to send anything back. The other bottles arrived in good condition, and the COA listed purity above 99%. Although the damage was frustrating, I really appreciated how quickly and easily the issue was resolved. Overall, the customer service was great, and I’d be happy to order again.
