BPC-157 and TB-500

BPC-157 and TB-500 are the two most frequently paired compounds in our catalog, so they share a category. They are structurally unrelated: BPC-157 is a 15-residue pentadecapeptide with the sequence Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val; TB-500 is a synthetic fragment of thymosin beta-4, the acetylated heptapeptide Ac-LKKTETQ at roughly 890 Da, not the full-length 43-residue protein.

Both products are independently tested for purity by HPLC and identity by mass spectrometry, with certificates published on the product page as testing is completed. For Research Use Only.
