BPC-157 Arginate vs Thymosin Beta-4

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

BPC-157 Arginate
Healing & Recovery

BPC-157 Arginate is the arginine salt form of BPC-157, identical in the GEPPPGKPADDAGLV peptide sequence but with improved water solubility, aqueous stability, and oral bioavailability. The arginate counterion buffers GI microenvironmental pH, reducing acid-catalyzed peptide degr...

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...
