The two leading regenerative peptides in the category — BPC-157 is a protective fragment from gastric juice (15 AA), TB-500 is the active fragment of Thymosin Beta-4 (G-actin binding). The literature often combines them.
| Spec | A BPC-157 | B TB-500 |
|---|---|---|
| Origin | Gastric juice protective protein (Sikiric, Zagreb) | Fragment 17-23 of Thymosin β-4 (Goldstein, GWU 1981) |
| Length | 15 amino acids | 7 amino acids (LKKTETQ) |
| Primary mechanism | Angiogenesis via VEGFR2 + NO signaling | G-actin binding → cell migration |
| Half-life | ~6 hours | 2-3 days |
| Dosing | Daily s.c. | 2× weekly s.c. |
| Gastric stability | Yes — oral administration viable | No |
| Studied for | Tendons, GI tract, nerve tissue, joints | Skeletal and cardiac muscle, skin, cornea |
Choose A when
GI tract regeneration, tendons (Achilles model), nerve tissue, joints. Oral option is a plus.

Systemic skeletal and cardiac muscle recovery, skin. More convenient at 2× weekly dosing.

Different mechanisms, not competitors. Standard recovery protocols combine them — BPC drives vasculature, TB-500 moves cells into it.
Frequently asked
Yes — this is the classic recovery duo. The two work through different but complementary mechanisms (angiogenesis + cell migration). Frequently sold as a 5+5 or 10+10 mg blend.
