About BPC-157 / TB-500 Mix

BPC-157 / TB-500 Mix is a co-lyophilised blend of two peptides, BPC-157 and TB-500, dried together into a single solid in one sealed vial. As a blend it has no single molecular formula, CAS number or molecular weight; each component keeps its own identifiers, listed on its own product page. The 20 mg figure is the combined net content of the vial.

The components differ widely in length. BPC-157 is a fifteen-residue peptide of 1419.53 g/mol, while TB-500 is catalogued as corresponding to thymosin β4, a single chain of forty-three residues. In reversed-phase HPLC each gives its own peak, so the chromatographic analysis of the blend has to resolve the two components from each other and from their related substances, and mass spectrometry confirms each against its own expected mass.

BPC-157 / TB-500 Mix structure and analytical profile

BPC-157 is a linear chain of fifteen residues, GEPPPGKPADDAGLV, with free termini, the formula C62H98N16O22 and a molecular weight of 1419.53 g/mol. TB-500 is catalogued under CAS number 77591-33-4, with the formula C212H350N56O78S and a molecular weight of 4963.44 g/mol, the identifiers of a forty-three-residue chain.

Co-lyophilised means both peptides were dried from one solution into a single cake, so every part of the solid holds both components. The vial's 20 mg is the combined net content, and each component's own identity data sit on the BPC-157 and TB-500 product pages.

With a mass gap of more than 3.5 kDa between them, the two components separate cleanly in reversed-phase HPLC and give two main peaks; purity is read for each peak against its own related substances. In electrospray mass spectrometry BPC-157 appears as singly and doubly protonated ions, [M+H]+ near m/z 1419.71, while TB-500 appears as a series of multiply charged ions deconvoluted to its own neutral mass.

The blend is a white to off-white lyophilised solid in one sealed vial. The sealed vial is stored at 2–8 °C short term, or at −20 °C and below for long-term storage, protected from light and away from repeated freeze-thaw cycles.

Questions about BPC-157 / TB-500 Mix

This preparation is a co-lyophilised blend of BPC-157 and TB-500. It is supplied in a sealed vial as a white to off-white lyophilised powder, in a 20 mg blend presentation.

Two: BPC-157, a fifteen-residue peptide of 1419.53 g/mol, and TB-500, catalogued as a forty-three-residue chain of 4963.44 g/mol. They are co-lyophilised together into one solid in a single sealed vial.

Freeze-dried together. Both peptides are dried from one solution into a single cake, so the vial holds one uniform solid rather than two separate powders.

Because it is a blend of two molecules, and CAS numbers, formulas and molecular weights describe one molecule each. BPC-157 and TB-500 keep their own identifiers, listed on their own product pages.

Reversed-phase HPLC separates the two components into their own main peaks, and mass spectrometry confirms each against its own expected mass: BPC-157 as [M+H]+ near m/z 1419.71, TB-500 as multiply charged ions deconvoluted to its neutral mass.

Order BPC-157 / TB-500 Mix directly from British Peptide Labs, a UK-registered company. It is supplied in a sealed 20 mg vial at £60.00 (£3.00 per mg). Every vial is ≥99% purity (HPLC), with independent third-party testing by PeptideVerify. Orders placed before 3pm Mon–Sat leave the same day by Royal Mail Tracked 24 for next-day tracked delivery.

BPC-157 / TB-500 Mix comes in one sealed vial: 20 mg at £60.00 (£3.00 per mg). Delivery is free on every order.

BPC-157 / TB-500 Mix is catalogued in the Peptide Fragments research area, where compounds are grouped by molecular class. The research area page lists each of them with its identifiers.
