CJC1295 without DAC

CJC-1295 without DAC is a synthetic Growth Hormone–Releasing Hormone (GHRH) analogue supplied as a lyophilized powder. Unlike its DAC-modified counterpart, this peptide exhibits a shorter half-life, making it a useful tool for researchers seeking to model pulsatile, physiologically representative growth hormone secretion dynamics in controlled laboratory settings. Each vial contains 10 mg of lyophilized peptide, verified by High-Performance Liquid Chromatography (HPLC) to a purity of ≥99%. The molecular formula is C₁₅₂H₂₅₂N₄₄O₄₂, with a molecular weight of approximately 3368.9 Da.

Research background

CJC-1295 without DAC has been studied in the context of GHRH receptor binding and the downstream stimulation of endogenous growth hormone release. It has been investigated as a model compound for examining pulsatile GH secretion patterns in in vitro systems, and referenced in the literature relating to growth hormone regulation and GHRH receptor dynamics. Its shorter half-life relative to DAC-modified analogues has made it a relevant reference compound in research designs that aim to replicate natural endocrine pulse intervals.

Reconstitution & handling

CJC-1295 without DAC is supplied as a lyophilized powder and should be reconstituted with bacteriostatic water (BAC water) prior to use. Add an appropriate volume of BAC water to the vial, then gently swirl — do not shake — until the powder is fully dissolved. Avoid vigorous agitation, which may degrade the peptide. Handle all solutions with standard laboratory precautions and keep the reconstituted peptide cold at all times when not in active use.

Storage & stability

The lyophilized powder should be stored refrigerated and protected from light and moisture. Once reconstituted, the solution should be kept refrigerated and used within a short, defined window to preserve integrity and experimental reproducibility. Repeated freeze-thaw cycles of the reconstituted solution should be avoided.

A batch-specific Certificate of Analysis (CoA), confirming identity and HPLC-verified purity, accompanies every order.
