CJC-1295 – 5mg

CJC-1295 without DAC, also known as Modified GRF(1-29), is a stabilised 29 amino acid GHRH fragment incorporating four amino acid substitutions that protect against enzymatic degradation while preserving full GHRH receptor binding activity without the Drug Affinity Complex albumin binding modification that characterizes CJC-1295 with DAC. Hudson Science’s formulation supplies 5mg as a lyophilized vial, preserving peptide structural integrity across storage conditions until reconstitution.

The absence of the DAC modification produces a fundamentally different pharmacokinetic profile from CJC-1295 with DAC. Without albumin binding, CJC-1295 No DAC carries a half-life of approximately 30 minutes; producing discrete, pulse like GHRH receptor activation episodes that closely mirror the natural pulsatile pattern of endogenous GHRH secretion. This short active window requires more frequent administration than the once weekly schedule of CJC-1295 with DAC, typically administered immediately before each GHRP co administration in research protocols but produces a more physiologically accurate replication of natural GHRH pulsatility that some research designs specifically require over the continuous baseline elevation produced by DAC modified CJC-1295.

The CJC-1295 No DAC and CJC-1295 with DAC distinction is the most pharmacokinetically significant differentiation within the GHRH analogue research family. Both compounds share identical GHRH receptor binding activity and downstream pituitary GH secretion stimulation. The half-life difference representing the sole but research critical variable between them. CJC-1295 No DAC’s pulsatile mimicry makes it the preferred GHRH analogue in research protocols examining physiological GH secretion patterns, while CJC-1295 with DAC’s sustained albumin bound profile suits protocols requiring extended continuous GHRH receptor engagement without frequent administration. CSD stocks both variants alongside Sermorelin and Tesamorelin, giving researchers access to the complete GHRH analogue half-life spectrum from a single verified Canadian supplier.
