    BPC-157/TB500 10MG

     $55.00 Add to cart

    BPC-157/TB-500 is a two-peptide combination formulation supplied as one lyophilized vial, pairing BPC-157, a synthetic 15-amino-acid fragment of human gastric protein BPC, with TB-500 (Thymosin Beta-4), a 43-amino-acid actin-sequestering peptide. The two are among the most frequently cited compounds in tissue-repair, cell-migration, and angiogenesis research, and are commonly studied side by side.

    Ipamorelin 10MG

     $45.00 Add to cart

    Ipamorelin is a synthetic pentapeptide acting as a selective agonist at the ghrelin receptor (GHSR-1a). That selectivity is why it appears so often in endocrinology research — it allows growth-hormone-axis signalling to be studied in isolation, without the broader hormonal activity seen with less selective secretagogues.

    This vial contains 10mg of ipamorelin as a lyophilized powder, equivalent to approximately 14.05 µmol.

    • Vial contents: 10mg lyophilized powder (batch IPA-10-260801-L001 tested at 10.72mg)

    • Molecular weight: 711.9 g/mol
    • Classification: Selective growth-hormone secretagogue, ghrelin receptor agonist
    • Sequence: Aib-His-D-2-Nal-D-Phe-Lys-NH2 (C-terminal amide)
