A three-peptide blend pairing the Wolverine stack with GHK-Cu.
Longevity & Skin
GHK-Cu's lesser-known cousin, researched mainly for hair follicles.
GLOW is not FDA-approved and rated 2/5 for evidence; AHK-Cu is not FDA-approved and rated 1/5. GLOW has more human evidence behind it. GLOW is banned in sport by WADA; AHK-Cu is not. Both are used for longevity & skin goals.

| Evidence | 2/5No studies of the blend itself. BPC-157 and TB-500 are mostly animal data; GHK-Cu's human data is topical. | 1/5Mainly in-vitro and ex-vivo hair follicle studies. Little to no controlled human data. |
| FDA status | Not FDA-approved | Not a drug; used as a cosmetic ingredient |
| WADA (sport) | Banned | Not on the Prohibited List |
| Also known as | GLOW blend, BPC-157 + TB-500 + GHK-Cu | Copper tripeptide-3, Alanyl-histidyl-lysine copper |
| How it works | 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. | In lab studies it stimulated growth of isolated human hair follicles and dermal papilla cells (the cells that control hair growth) and reduced cell death in those cells. Like GHK-Cu, it delivers copper and may encourage collagen production in skin cells. |
