Research material and lot documents
Wolverine peptide for sale listings describe two different formats, a pair of separate vials or one combined product, so the stated amounts, the format and the lot reports need to be read together. The Curo recovery catalog lists BPC-157 + TB-500, 5 mg + 5 mg, as a pair of separate vials. The Wolverine peptide page explains what the name covers.
TB-500 5 mg listing at Curo for the single TB-500 vial.
Curo's COA library, which publishes lot reports by lot number.
Curo's testing-method page, which lists the fields each report covers.
The catalog listing states one BPC-157 compound and one TB-500 compound, 5 mg of each, packaged separately and not pre-mixed. The masses add to 10 mg by arithmetic, but they describe two peptides, so 10 mg is not an amount of either one.
FDA's July 2026 briefing document on BPC-157 describes websites that sell BPC-157 and TB-500 as one multiple-ingredient product, some labeled for research purposes only. Source: FDA briefing document on BPC-157, July 23-24, 2026. A combined product carries one label for two molecules. A pair of vials carries two labels, and each vial can have its own report.
The testing page describes identity by FTIR or LC-MS, purity by HPLC as a percentage of detected peak area, fill as milligrams per vial, and endotoxin and sterility where available. Those fields are the seller's description of its own reports, so a reader can check each one against the vial label and lot number.
For identity by mass, PubChem lists 1419.5 g/mol for BPC-157 and 889.0 g/mol for the TB-500 fragment. Sources: PubChem BPC-157 record and PubChem TB-500 fragment record. A mass near 889 g/mol agrees with the fragment record. Full-length thymosin beta-4 has a reference weight near 4963 g/mol, so a mass near that value agrees with the protein record. Source: PubChem thymosin beta-4 record, CID 45382195.
Identity names the molecule in the sample. Purity gives the target's share of the detected peak area, and it does not name the molecule. Fill gives the measured amount in a vial. A high purity figure for a vial labeled TB-500 therefore needs an identity result beside it.
A report documents one lot. It does not document a result in an experiment or in people. FDA's statements on human safety information are on the BPC-157 and TB-500 together page.
The catalog listing above says its pair is not pre-mixed. Other sellers describe combined products, so each listing needs its own reading.
No. It means 5 mg of BPC-157 and 5 mg of TB-500 by label.
FDA's TB-500 briefing calls it a common name used for multiple salts and derivatives. An identity result in the lot report shows what the sample contains. Source: FDA briefing document on TB-500, July 23-24, 2026. The TB-500 vs BPC-157 page sets the fragment and the protein side by side.
