BPC-157 vs TB-500
BPC-157 is a synthetic pentadecapeptide (15 amino acids). TB-500 is a 43-amino acid fragment of Thymosin Beta-4 (Tβ4) active region. They are different materials with different identities and different research literatures; the table below sets the two identities side by side, the sections after it summarise what each is studied for, and the certificate rows show how each has tested.

What is the difference between BPC-157 and TB-500?
BPC-157 is a synthetic pentadecapeptide (15 amino acids); TB-500 is a 43-amino acid fragment of Thymosin Beta-4 (Tβ4) active region. BPC-157 has 15 residues and TB-500 has 43. Their molecular identities, the models they have been studied in and their certificate records are all listed on this page.
Are BPC-157 and TB-500 sold together?
Yes. Glow and KLOW combine them in one vial; the blend has its own catalogue page and its own certificates.
How has each tested?
BPC-157: 4 documented third-party HPLC results from 99.25% to 99.86%. TB-500: 5 documented results from 99.17% to 99.86%. Every certificate is published and linked from each compound's lab results page.
Which one should a research project use?
That depends on the pathway and model under study, which is a scientific question this page does not answer. What it does is put the identities, the described mechanisms and the analytical records side by side so the choice can be made on documented facts. Both materials are for laboratory research use only.
For research use only. Not for human or veterinary use. Nothing on this page describes or recommends use in people or animals.
