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.

DSIP 5 mg – Delta Sleep Inducing Peptide

DSIP (Delta Sleep Inducing Peptide) is a naturally occurring nonapeptide (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) first identified in 1977 from cerebral venous blood of rabbits during induced sleep. Unlike conventional sedatives, DSIP does not force sleep but appears to modulate the architecture and quality of natural sleep patterns, making it a unique tool for chronobiology and sleep research.

Research Background

Sleep architecture modulation – DSIP has been studied for its effects on delta-wave (slow-wave) sleep, the deepest and most restorative phase of the sleep cycle. Rather than acting as a sedative, it appears to promote the natural transition into and maintenance of deep sleep stages.

Stress and cortisol – Research indicates DSIP may modulate the hypothalamic-pituitary-adrenal (HPA) axis, with studies reporting effects on cortisol rhythms and stress-response adaptation. This has positioned it as a research compound at the intersection of sleep and stress biology.

Opioid system interaction – Some studies suggest DSIP influences endogenous opioid systems, potentially affecting pain perception and withdrawal models, though the precise receptor interactions remain under investigation.
