BPC-157 Arginate
Also known as: BPC-157 Arginine Salt, Pentadeca Arginate, PDA, Oral BPC-157
An oral-stable form of BPC-157 made with an arginine salt that helps it survive stomach acid much better than the standard acetate form. Designed for people who want the potential benefits of BPC-157 without injections. Human clinical data is still extremely limited.
How it works
BPC-157 Arginate works the same way as standard BPC-157, modulating the nitric oxide system, upregulating growth factors (VEGF, EGF), and promoting blood vessel growth. The arginine salt provides a protective buffer that makes the peptide much more resistant to breakdown in acidic environments like your stomach, so more of it survives to reach your gut and potentially your bloodstream.
Common uses
- Gut healing and GI inflammation
- Tendon, ligament, and joint support (oral route)
- General tissue repair and recovery
- Alternative to injectable BPC-157
Side effects
- Very limited human safety data
- Mild GI discomfort reported occasionally
- Nausea (rare, anecdotal)
- Unknown long-term effects
- Human bioavailability data not established
Key research
- 2025 pilot study: IV BPC-157 at 10 mg and 20 mg doses in two adults showed no adverse effects on cardiac, liver, kidney, thyroid, or glucose markers
- Stability studies show arginate salt form is significantly more resistant to acid degradation than acetate form
- Same preclinical evidence base as standard BPC-157 (rodent studies on tendon healing, gut protection, etc.)
Safety notes
- Standard BPC-157 was added to FDA's list of substances that cannot be compounded (2023-2024)
- The arginate/oral form exists in a gray area. Many supplement companies sell it as a dietary supplement
- No completed human clinical trials for any form of BPC-157
- Quality and purity vary greatly between brands. Look for third-party COA with 98%+ purity
- Human oral bioavailability has not been established in published studies
