BPC-157 vs TB-500
Research library
BPC-157 and TB-500 are the two peptides researchers most often pair in tissue repair studies. They come from different sources and are studied for different mechanisms.
| BPC-157 | TB-500 | |
|---|---|---|
| Origin | Partial sequence of a protein from human gastric juice | Based on the actin-binding region of thymosin beta-4 |
| Size | 15 amino acids | Short synthetic fragment of a 43 amino acid protein |
| Main mechanism studied | Blood vessel formation, nitric oxide system, tendon cell outgrowth | Actin binding, cell migration |
| Research areas | Tendon, ligament, gut lining, gut-brain axis | Wound repair, cardiac and corneal models |
| Evidence base | Mostly animal and cell studies | Mostly animal and cell studies on thymosin beta-4 |
| Regulatory status | Not an approved medicine; on WADA Prohibited List | Not an approved medicine; on WADA Prohibited List |
Why are they studied together?
Because they act on different pathways, BPC-157 (blood vessel and growth factor signalling) and TB-500 (cell migration through actin) are often combined in preclinical tissue repair research to look at complementary effects.

Frequently asked questions
What is the difference between BPC-157 and TB-500?
BPC-157 is a 15 amino acid fragment of a gastric protein studied mainly for blood vessel and tendon effects in animal models. TB-500 is based on thymosin beta-4 and is studied mainly for its role in cell migration through actin binding.
Why are BPC-157 and TB-500 combined?
They act on different biological pathways, so researchers combine them to study complementary effects in tissue repair models. Meytrix supplies the pair as the Wolverine Stack.
Are BPC-157 and TB-500 legal in South Africa?
Neither is a registered medicine. Meytrix supplies both strictly for laboratory research use only, not for human consumption.
