## Description

These capsules provide the pentadecapeptide BPC-157 in its arginate (arginine salt) form, portioned at 500 mcg of peptide per capsule and packed in bottles of 30 or 60. The peptide is the 15-residue sequence Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val, originally reported as a partial sequence of a protein recovered from gastric juice — hence the prominence of gastrointestinal models in its research literature.

“Arginate” describes the counter-ion, not the peptide chain: the acidic peptide is paired with arginine instead of the usual acetate. Choice of salt is a routine formulation variable in peptide chemistry — it influences hygroscopicity, dissolution and the residual counter-ion seen on analysis — which is why suppliers of oral products often specify it. Sequence, molecular formula and mass are exactly the same as in our free-peptide vials.

## Frequently asked questions

### What does “arginate” mean?

It names the counter-ion: the peptide comes as an arginine salt instead of the more usual acetate. Sequence, molecular formula and molecular mass of BPC-157 stay the same; the salt affects characteristics such as moisture uptake and dissolution, not the identity of the peptide.

### What is the peptide content per capsule?

Every capsule holds 500 mcg of BPC-157, expressed as peptide mass. Bottles contain 30 or 60 capsules, and the content per capsule is repeated on the lot's Certificate of Analysis so you can cross-check it with your records.

### How do they compare with the standard BPC-157 capsules?

Each provides 500 mcg of the identical 15-residue peptide per capsule. Only the counter-ion differs — arginate instead of the standard salt — a formulation variable that researchers sometimes treat as the experimental factor in dissolution or stability comparisons.

### Is the peptide tested by an independent lab?

Yes. An independent laboratory analyses the BPC-157 input by HPLC to confirm ≥99% purity and runs identity tests, and the COA for your batch can be requested. Check that the lot on the bottle matches the COA before you record data.

### What are the storage conditions?

Keep capsules in the closed bottle somewhere cool and dry, out of direct light. Refrigeration prolongs stability; leave the desiccant inside and let a cold bottle reach room temperature before opening so condensation cannot reach the capsules.

### Does orally delivered BPC-157 enter the circulation?

This is still unresolved. Some published work describes stability in gastric juice, which is what drives oral-format experiments, yet systemic exposure remains poorly characterised. Studies tackling the question usually add a parenteral reference arm and measure plasma levels directly.
