BPC-157 (Body Protection Compound-157) is a synthetic pentadecapeptide consisting of 15 amino acids, derived from a protein naturally found in human gastric juice. It is widely studied in preclinical research for its role in tissue repair, angiogenesis, and cytoprotective signalling.

How do I reconstitute BPC-157?

Reconstitute with 1-2 ml of bacteriostatic water. Allow the vial to reach room temperature, inject solvent gently down the inside wall, and swirl gently. Never shake. Store reconstituted solution at 2-8°C and use within 4-6 weeks.

What purity is BioLab's BPC-157?

Every batch is independently tested via HPLC and mass spectrometry to confirm 99%+ purity and correct molecular identity. A batch-specific Certificate of Analysis is available with every order.

How should I store BPC-157?

Store lyophilised vials at -20°C, protected from light and moisture. Once reconstituted with bacteriostatic water, store at 2-8°C and use within 4-6 weeks. Avoid repeated freeze-thaw cycles.

SNAP-8 20 mg – SNARE Complex Research Peptide

SNAP-8 (Acetyl Octapeptide-3) is an extended analogue of Argireline (Acetyl Hexapeptide-3) that competitively inhibits SNARE complex formation by mimicking the N-terminal domain of SNAP-25. The SNARE complex (soluble N-ethylmaleimide-sensitive factor attachment protein receptor) is the molecular machinery that mediates vesicle fusion and neurotransmitter release at synapses and neuromuscular junctions.

Research Background

SNARE complex modulation – SNAP-8 competes with endogenous SNAP-25 for incorporation into the SNARE complex, reducing the efficiency of vesicle docking and fusion. This mechanism has been studied in neuromuscular junction models where reduced neurotransmitter release translates to decreased muscle contraction signalling.

Enhanced activity vs Argireline – As an octapeptide (8 amino acids), SNAP-8 has two additional residues compared to the hexapeptide Argireline (6 amino acids). Research suggests this longer sequence provides improved SNARE complex binding and greater biological activity in comparative studies.

Skin biology applications – SNAP-8’s neuromuscular modulation has been studied in cosmetic peptide research, where reduced muscle microcontractions may affect dynamic wrinkle formation. This positions it alongside Matrixyl as a complementary skin biology research tool.
