Pentadeca Arginate (PDA)
Arginate-salt analog of BPC-157 developed for improved injection stability and tissue repair.
No acute perceptible effect; reported benefits build over days to weeks of consistent use.
Store the lyophilized powder refrigerated (2 to 8 C), or frozen for long-term storage, protected from light. After reconstitution with bacteriostatic water, keep refrigerated and use within about 4 weeks.
Clinical Evidence
What the literature says
Scientific Overview
Pentadeca Arginate (PDA) is a 15-amino-acid peptide derived from the BPC-157 sequence and complexed with an arginate salt for greater stability and longer shelf life than BPC-157 acetate. Marketed as a research-grade alternative as compounding pharmacies pivoted away from BPC-157 after the FDA's 2023 503A removal. Human trial evidence is limited.
