Cosmetic & skin research peptides
Cosmetic science relies on peptides studied in skin-cell and extracellular-matrix models. GHK-Cu, the copper(II) complex of the tripeptide glycyl-histidyl-lysine, was first isolated from human plasma in 1973 and has since been studied in fibroblast and keratinocyte culture for collagen and matrix gene expression. AHK-Cu is a closely related copper tripeptide studied in dermal papilla and fibroblast cell culture.
Snap-8 (acetyl octapeptide-3) is an extension of acetyl hexapeptide-8 studied in vitro for its interaction with the SNARE complex. MT-2 is a cyclic analogue of α-melanocyte-stimulating hormone used in melanocortin-receptor research, including pigmentation biology at the MC1 receptor.

Questions
More on ordering and shipping and batch reports.
Are these cosmetic peptides ready-to-use skincare?
No. They are supplied as lyophilised research materials for laboratory work, not as cosmetics or finished products, and are not for application to people or animals.
Where are the certificates of analysis?
Each vial carries a lot number. Certificates of analysis are published on the batch-report page under that lot number as the testing laboratory issues them. Where a lot has no published report yet, the product page says so rather than showing placeholder results.
Other research areas
For research use only. All products are sold strictly for in-vitro laboratory research. They are not drugs, foods, supplements or cosmetics, are not for human or veterinary use, and have not been evaluated by the FDA. Purchasers must be 21 or older.
