BPC-157 Arginate vs Acetate: What the Salt Form Changes
BPC-157 arginate and acetate differ only in counter-ion, not in peptide. What a salt form affects, why published research used no carrier, and how to check.
Tissue repair research
Published work on wound healing, tendon and ligament models, angiogenesis and the signalling behind them. Model species and injury model are stated for every result, since repair findings transfer poorly between models.
