The peptide library
Every entry states its evidence level and approval status up front. Filter by what the research shows, not by what a product page claims.
AOD-9604
A fragment of human growth hormone marketed for fat loss. Human trials were completed — and did not show meaningful weight loss.
Afamelanotide (melanotan I)
The approved melanotan: a tanning-hormone analogue licensed for a rare light-sensitivity disease, not for tanning.
Collagen peptides
Hydrolysed collagen sold as a food supplement for skin, joints and bone. Modest, real effects in trials — but far smaller than supplement marketing suggests.
GHK-Cu
A copper-binding tripeptide found naturally in human plasma and skin, used in cosmetic formulations for skin remodelling and studied for wound healing.
GLOW blend (BPC-157, GHK-Cu, TB-500)
A three-peptide skin-and-repair blend sold on collagen and healing claims that no trial has tested.
Melanotan II
A synthetic melanocortin analogue originally studied as a tanning and sexual-health drug. Abandoned as a medicine and sold illegally as a tanning product.
