Description
This blend puts 5 mg of BPC-157 and 5 mg of TB-500 into a single vial, so labs that always run the two compounds together can skip weighing and combining them separately.
A two-peptide vial with a fixed split
Blends are convenient but they change how verification works. A single chromatogram of the vial should show two main peaks, one for each peptide, and their areas depend on each compound’s response at the detection wavelength as well as on the mass split. That is why a blend certificate reads differently from a single-compound one, and why the identity table below lists both molecules.
The 10 mg total is sized for method development and short series. For longer programmes, the 20 mg blend halves the number of vials to track, while separate BPC-157 and TB-500 vials remain the better choice when the ratio itself is a variable in the experiment.
Compound identity and specification
| Component | Sequence | Formula | Mass (g/mol) | CAS |
|---|---|---|---|---|
| TB-500 CID 62707662 | Ac-Leu-Lys-Lys-Thr-Glu-Thr-Gln (acetylated LKKTETQ, the thymosin beta-4 17-23 region) | C38H68N10O14 | 889.0 | 885340-08-9 |
| BPC-157 CID 9941957 | Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val (GEPPPGKPADDAGLV) | C62H98N16O22 | 1419.5 | 137525-51-0 |
Questions about BPC-157 & TB-500 Blend 10mg
What is the mass split in this vial?
Equal parts: 5 mg of BPC-157 and 5 mg of TB-500, for 10 mg in total.
Why does the chromatogram show two peaks?
Because the vial contains two different peptides. Each has its own retention time; purity is assessed for each component.
Should I buy the blend or two separate vials?
Choose the blend when the ratio is fixed. Choose separate vials when you need to vary the ratio or run each compound on its own.

Literature notes: Published work concerns full-length thymosin beta-4 or its LKKTETQ actin-binding fragment. Equivalence between those and material marketed as TB-500 is not established in the literature. The published base for this compound is small and concentrated in a limited number of research groups, with little independent replication of in vivo findings.
