Longevity & Skin
A natural copper-binding tripeptide with decades of skin research.
Longevity & Skin
A three-peptide blend pairing the Wolverine stack with GHK-Cu.
GHK-Cu is not FDA-approved and rated 3/5 for evidence; GLOW is not FDA-approved and rated 2/5. GHK-Cu has more human evidence behind it. GLOW is banned in sport by WADA; GHK-Cu is not. Both are used for longevity & skin goals.

| Evidence | 3/5Several small human topical/cosmetic studies; injection data is mainly preclinical. | 2/5No studies of the blend itself. BPC-157 and TB-500 are mostly animal data; GHK-Cu's human data is topical. |
| FDA status | Cosmetic ingredient; injectable not approved | Not FDA-approved |
| WADA (sport) | Not on the Prohibited List | Banned |
| Also known as | Copper tripeptide-1, Glycyl-L-histidyl-L-lysine copper | GLOW blend, BPC-157 + TB-500 + GHK-Cu |
| How it works | Delivers copper to tissue, stimulates collagen and glycosaminoglycan synthesis, supports wound remodeling, and appears to reset expression of many genes toward a younger profile (gene-expression studies). | BPC-157 supports local repair and blood-vessel growth, TB-500 helps cells move to injured tissue, and GHK-Cu delivers copper and drives collagen signaling. How they act together has not been studied. |
| Half-life | Short (minutes–hours); effects driven by gene/repair signaling | Mixed: each component differs; all are short-acting signals |
