The BPC-157 / TB-500 Blend pairs two research peptides in one vial: BPC-157, a synthetic pentadecapeptide, and a compound marketed as TB-500, typically a synthetic fragment of thymosin beta-4 rather than the full native peptide. The only published study testing this exact combination found no added benefit from combining them over either peptide alone. Available in 5mg/5mg and 10mg/10mg for laboratory research use only.
HPLC certified

Each order ships as a combined-vial BPC-157 / TB-500 research compound in your choice of 5mg/5mg or 10mg/10mg, manufactured for laboratory research use only.
| Product | BPC-157 / TB-500 Blend |
|---|---|
| Components | BPC-157 and a compound marketed as TB-500 |
| BPC-157 identity | CAS 137525-51-0, formula C62H98N16O22, MW 1,419.56 g/mol, PubChem CID 9941957, sequence GEPPPGKPADDAGLV — as established for this supplier's standalone BPC-157 listing |
| TB-500 identity | Not independently confirmed. "TB-500" is a commercial name; FDA's 2026 briefing materials treat TB-500 free base and TB-500 acetate as two distinct substances, neither the same as full-length thymosin beta-4. |
| Variant composition | 5mg/5mg and 10mg/10mg as printed on the label. Whether each number is the milligram amount of each named component has not been independently confirmed. |
| Purity | Not independently verified — no batch-specific COA is currently published |
| Identity confirmation method | Not publicly documented at this time |
| Available Sizes | 5mg/5mg / 10mg/10mg |
| Intended Use | Laboratory research only (RUO) |
When your order arrives, match the lot number printed on the vial to the lot number on the COA before beginning any work. Until a batch-specific COA is published for this blend, treat any purity or identity figure shown elsewhere on this listing as a supplier claim, not an independently verified result.
BPC-157 and TB-500 get sold as a pair, but only one study has ever tested them together — and it found no added benefit over TB-500 alone.
TB-500 isn't just another name for Thymosin Beta-4 — most vendor pages treat it that way. What research actually supports, and how it compares to BPC-157.
HCG and LH bind the exact same receptor — yet research shows they send measurably different signals once they do. Here's what's actually established about HCG's structure, mechanism, and the FDA's position on HCG weight-loss claims.
