Fix the salt form first
Acetate, arginine or salt-free is a specification decision, not a detail: it changes the peptide mass per vial and the pH of the solution you make from it. Our codes distinguish all three.

Sequences studied in tissue-repair, angiogenesis and matrix-remodelling models — supplied with the salt form, the fragment identity and the peptide mass that make a comparison possible.
Overview
What the repair range covers.
This range centres on BPC-157, a synthetic pentadecapeptide whose sequence corresponds to a fragment found in gastric juice, together with the thymosin β4 fragments (TB-500 and its 17–23 fragment), the copper tripeptide GHK-Cu, the relaxin analogue B7-33 and the erythropoietin-derived ARA-290. They appear throughout the tissue-repair, angiogenesis and matrix-remodelling literature.
Two things make these hard to compare between suppliers. The first is salt form: BPC-157 is sold as acetate, as the arginine salt and salt-free, and the three weigh differently per milligram of peptide. The second is fragment identity: TB-500 is the 43-amino-acid thymosin β4, while the 17–23 fragment is seven residues — related, not interchangeable.
- BPC-157 in acetate, arginine and salt-free forms, each with net peptide content on the COA
- TB-500 and the 17–23 fragment held as separate catalogue items
- GHK-Cu released against copper content, not against colour
- ≥98% by HPLC with MS identity for every batch
Catalogue

Every item below is a separate code with its own specification. Where a product exists in several salt forms, each form is listed and priced separately.

Specification
What to specify.
Three things decide whether two quotations for the “same” peptide are actually the same material.
State the fragment
TB-500 and the 17–23 fragment have different molecular weights and different research histories. The code on the certificate names which one shipped — check it against your protocol.
Ask for net peptide content
HPLC purity and peptide mass diverge by 10–20% on lyophilised material. For a molar solution, net peptide content is the number that matters; many suppliers do not measure it.
