Description
At 10 mg of each peptide, this is the blend format for programmes that have settled on a one-to-one ratio and want fewer vials to log, store and match to certificates.
The larger two-peptide blend
Everything about the 10 mg blend applies here at double the fill: the same two sequences, the same equal split, the same two-peak chromatogram. What changes is logistics. One 20 mg vial replaces two smaller ones, which halves the number of cap-and-crimp records to keep and the number of times a vial is opened in the freezer.
Because both components are short, readily soluble peptides, the blend dissolves as easily as either compound alone. Keep in mind that once dissolved, the two peptides share a solution and a storage history; if one component’s stability is the limiting factor in your assay, plan around that one.
Compound identity and specification
| Component | Sequence | Formula | Mass (g/mol) | CAS |
|---|---|---|---|---|
| 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 |
| 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 |
Questions about BPC-157 & TB-500 Blend 20mg
Is the 20 mg blend the same ratio as the 10 mg?
Yes. Both are equal-mass blends; the 20 mg vial holds 10 mg of BPC-157 and 10 mg of TB-500.
Do quantity breaks apply to blends?
They do, exactly as for single compounds: 5% off from two vials up to 35% off at ten or more vials in the cart, blends and single compounds counted together.
How is a blend matched to its certificate?
The same way as any vial: by the cap and crimp colour recorded on the certificate posted on our COAs page.

Literature notes: 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. 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.
Certificates for our compounds are posted on the certificates of analysis page and matched to vials by cap and crimp colour. If the one for this product is not up yet, contact the order desk.
