Sold by research-peptide vendors as a single multi-peptide vial combining a copper peptide with two tissue-repair peptides and an anti-inflammatory tripeptide, marketed for recovery, wound healing, and skin/collagen support.

Rationale

GHK-Cu is included primarily for its collagen-synthesis and wound-healing signaling. BPC-157 and TB-500 are frequently combined with each other on their own (see the tb-500-bpc-157 research pairing) for proposed complementary tissue-repair mechanisms. KPV contributes anti-inflammatory tripeptide activity distinct from the other three. There are no controlled trials evaluating this four-peptide combination as a whole — the rationale here is inferred from each peptide's individual, largely preclinical mechanism, not from data on the blend itself.

5 : 1 : 1 : 1 — GHK-Cu : BPC-157 : TB-500 : KPV

Multiple independent research-peptide vendors list an 80mg vial containing 50mg GHK-Cu, 10mg BPC-157, 10mg TB-500, and 10mg KPV (a 5:1:1:1 ratio by mass). This figure was consistent across every vendor listing checked; no manufacturer-published label or independent third-party lab panel breakdown of actual vial content was available to verify it independently.
