Comparison / Recovery Class
BPC-157 vs TB-500.
Two recovery-class reference standards, frequently paired in research. This is how they differ and why laboratories stock both.
At a glance
| Property | BPC-157 | TB-500 |
|---|---|---|
| Origin | Partial sequence of BPC from gastric juice | Synthetic Thymosin β4 fragment |
| Length | 15 amino acids | 17-amino-acid active fragment |
| Molecular weight | ≈ 1419.5 Da | ≈ 1923 Da |
| Research focus | Tissue, GI-lining, vascular studies | Cellular migration, muscle tissue studies |
| Lumera Labs price | $39 CAD (5 mg) | $69 CAD (10 mg) |
| Typical pairing | Frequently co-referenced; pre-blend available | |
When to source both
Research comparing recovery-class peptides typically requires both on hand. Cross-validation between the two molecules in a single assay run eliminates inter-lab variance. Lumera Labs offers a pre-blended reference vial for teams running combined assays.
Documentation
Both compounds ship with per-lot Certificates of Analysis documenting HPLC purity, mass-spec identity, and endotoxin clearance. Cold-chain shipping is standard from our Kelowna, BC facility.
