BPC-157 vs Thymosin Beta-4

BPC-157 vs Thymosin Beta-4 — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

BPC-157
Healing & Recovery

BPC-157 is a synthetic 15-amino acid peptide derived from gastric juice. It accelerates tissue repair, tendon healing, and gut protection via angiogenesis and growth hormone receptor upregulation. Orally bioavailable and stable in gastric acid. Extensive preclinical evidence acro...

Thymosin Beta-4
Healing & Recovery

Thymosin Beta-4 (TB-4) is the full-length 43-amino acid actin-sequestering peptide from which the commonly used research fragment TB-500 (residues 17-23, LKKTETQ) is derived. TB-4 is the most abundant thymosin-family protein in virtually all mammalian cells, where it maintains th...
