Pentadeca Arginate (PDA) for Muscle Gain
Arginate-salt analog of BPC-157 developed for improved injection stability and tissue repair.
Why Pentadeca Arginate (PDA) for muscle gain?
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.
Muscle Gain context: Increasing lean mass via GH/IGF-1 axis, satellite-cell activity, or anabolic signaling. Pentadeca Arginate (PDA) fits this goal because its category (Recovery) and benefit profile align with the underlying mechanism.
Benefits relevant to muscle gain
- Tendon and ligament healing
- Better stability than BPC-157 acetate
- Anti-inflammatory
