What is BPC-157 Arg?
BPC-157 Arg is the arginine salt form of BPC-157 (Body Protection Compound-157) — a synthetic 15-amino acid pentadecapeptide (GEPPPGKPADDAGLV) derived from a protective gastric juice protein.
Forming the arginine salt dramatically improves aqueous solubility and oral bioavailability versus the plain BPC-157 free acid, making it the preferred variant for oral tablet delivery in research.
The peptide retains identical biological activity: activating NO synthase and VEGF pathways to accelerate tissue repair in tendon, ligament, muscle, gut mucosa, and bone. Stable in gastric acid — particularly well-suited to oral delivery. Research use only.

Frequently Asked Questions
What is BPC-157 Arg and how does it differ from standard BPC-157?
BPC-157 Arg is the arginine salt form of BPC-157. The arginine salt significantly improves aqueous solubility and oral bioavailability compared to plain BPC-157 free acid. The peptide sequence GEPPPGKPADDAGLV is identical — arginine is the counter-ion, not part of the peptide chain.
This makes BPC-157 Arg the preferred form for oral tablet delivery in research. How are BPC-157 Arg tablets supplied?
Vesta BPC-157 Arg is supplied as pre-dosed oral tablets at 500mcg per tablet — no reconstitution required.
Each tablet contains BPC-157 as the arginine salt for improved solubility. 100 tablets per bottle. What purity is Vesta BPC-157 Arg and how is it verified?
Vesta BPC-157 Arg is ≥99% pure by HPLC on every batch, with MS confirmation of the GEPPPGKPADDAGLV sequence and arginine salt identity. COA is published on the product page and verifiable at verify.janoshik.com.
