Overview
BPC-157 arginate capsules supply the pentadecapeptide BPC-157 as its arginine salt, pre-measured at 500 mcg of peptide per capsule in 30-count and 60-count bottles. BPC-157 itself is a 15-amino-acid sequence — Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val — first described as a partial sequence of a protein isolated from gastric juice, which is why gastrointestinal research models feature so heavily in the literature around it.
The arginate designation refers to the counter-ion rather than the peptide backbone: the acidic peptide is paired with arginine instead of the more common acetate. Salt form is a standard formulation variable in peptide chemistry, affecting hygroscopicity, dissolution behaviour and the residual counter-ion that appears on analysis, and vendors of oral formats often specify it for that reason. The peptide sequence, molecular formula and mass are unchanged from the free-peptide vial product.

Questions about BPC-157 Arginate Capsules
What does 'arginate' mean here?
It identifies the counter-ion. The peptide is supplied as an arginine salt rather than the more common acetate. The BPC-157 sequence, molecular formula and molecular mass are unchanged; salt form influences properties such as hygroscopicity and dissolution behaviour, not peptide identity.
How much peptide is in each capsule?
Each capsule contains 500 mcg of BPC-157, stated as peptide mass. Bottles are supplied in 30-count and 60-count sizes, and the per-capsule content is restated on the lot-matched Certificate of Analysis so it can be checked against your records.
How do these differ from the standard BPC-157 capsules?
Both deliver 500 mcg of the same 15-residue peptide per capsule. The difference is the counter-ion — arginate versus the standard salt form — which is a formulation variable researchers sometimes hold as the experimental factor when comparing dissolution or stability.
Is the peptide third-party tested?
Yes. The BPC-157 input is analysed by an independent laboratory using HPLC to confirm ≥99% purity along with identity testing, and a lot-matched COA is available for the batch supplied. Match the lot on the bottle to the COA before recording data.
How should the capsules be stored?
Store them in the sealed bottle in cool, dry conditions away from direct light. Refrigeration extends shelf stability; keep the desiccant in place and let a refrigerated bottle warm before opening so that condensation does not reach the capsule contents.
Does oral BPC-157 reach the bloodstream?
That is an open research question. Part of the published literature reports stability in gastric juice, which motivates oral-format experiments, but systemic exposure has not been well characterised. Studies addressing it normally include a parenteral reference arm and direct plasma measurement.
