What Pentadeca Arginate is
The same 15 amino acid sequence as BPC-157 with an arginine salt instead of acetate, created as a compounding workaround; it has no studies of its own and inherits BPC-157's animal-only evidence.
Pentadeca arginate appeared after the FDA placed BPC-157 in Category 2 of the compounding bulk list in 2023. Its peptide sequence (GEPPPGKPADDAGLV) is identical to BPC-157; only the counterion differs.
Mechanism: Presumed identical to BPC-157: FAK-paxillin, VEGFR2 and nitric-oxide signaling supporting angiogenesis and tissue repair in animal models.
Regulatory history: Not approved; not an FDA-recognized distinct substance
