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.

Matrixyl 20 mg – Collagen-Stimulating Lipopeptide

Matrixyl is the trade name for palmitoyl pentapeptide-4 (Pal-KTTKS), a synthetic lipopeptide developed by Sederma. The core sequence KTTKS is a fragment of type I procollagen that acts as a matrikine – a peptide fragment of extracellular matrix proteins that signals cells to produce new matrix components.

Research Background

Collagen synthesis – Matrixyl has been shown to stimulate production of collagen types I, III, and IV in fibroblast models. The KTTKS sequence mimics a collagen breakdown fragment, effectively signalling fibroblasts that matrix repair is needed.

Fibronectin production – Beyond collagen, Matrixyl stimulates fibronectin synthesis, a glycoprotein critical for cell adhesion, migration, and wound healing in the extracellular matrix.

Palmitoyl modification – The palmitic acid chain enhances membrane permeability and stability, allowing the peptide to cross cell membranes and reach intracellular targets more effectively than the unmodified KTTKS sequence alone.
