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.

CJC-1295 5mg UK (No DAC / MOD GRF 1-29)

This is CJC-1295 without DAC. The same compound is also sold as MOD GRF 1-29. If you are looking for CJC-1295 with drug affinity complex (the long-acting version), see our CJC-1295 with DAC 5mg or 10mg options.

What is the difference between CJC-1295 with and without DAC?

Both products contain the same modified GRF 1-29 peptide sequence with four substitutions (Ala2, Ala8, Ala15, Leu27) that protect it from DPP-IV enzymatic degradation. The difference is a chemical addition called a Drug Affinity Complex (DAC).

Research Applications

CJC-1295 (no DAC) is studied as a selective GHRH receptor agonist. It activates the same receptor as endogenous growth hormone releasing hormone, triggering pulsatile GH release from pituitary somatotrophs. The four amino acid substitutions extend the functional half-life from about 7 minutes (native GHRH) to roughly 30 minutes, which is long enough to produce a full GH pulse but short enough to preserve physiological rhythm.

The most commonly studied research protocol pairs CJC-1295 (no DAC) with a GHS-R agonist such as Ipamorelin or GHRP-2. This dual activation produces synergistic GH release that is greater than either pathway alone. For convenience, we also stock pre-combined blends: Ipamorelin + MOD GRF blend and GHRP-2 + MOD GRF blend.

Frequently Asked Questions

What is DAC in CJC-1295?
DAC stands for Drug Affinity Complex, a reactive maleimide group added to the peptide that forms a covalent bond with serum albumin. This albumin binding creates a circulating reservoir, extending the half-life from 30 minutes to 6-8 days. The DAC version produces sustained GH elevation; the non-DAC version (this product) produces pulsatile GH release.

Is CJC-1295 legal to buy in the UK?
CJC-1295 is sold in the UK strictly as a research chemical for laboratory use, not for human consumption. It is not licensed as a medicine in the UK. Purchasers are responsible for complying with all applicable regulations.

How do I reconstitute CJC-1295 5mg?
Typically reconstituted with 2ml of bacteriostatic water for a concentration of 2.5 mg/ml. Full guide: How to Reconstitute Peptides.
