Frequently Bought Together
CJC-1295 with DAC is a long-acting synthetic analog of growth hormone releasing hormone (GHRH), modified with a Drug Affinity Complex to extend its biological half-life from under 10 minutes to 6 to 8 days, studied for its role in sustained GH secretion and IGF-1 elevation. Growth hormone does not decline because your body forgets how to make it. It declines because the signals that trigger its release become shorter, weaker, and less frequent with age. By 40, GH pulse amplitude in most adults has dropped to roughly half of adolescent levels. By 60 the decline is steeper still. CJC-1295 with DAC addresses the signal problem rather than supplementing GH directly. It is a structural analog of GHRH(1-29) modified with a Drug Affinity Complex, a maleimide-lysine linker that forms a covalent bond with circulating serum albumin after injection. That bond transforms a peptide with a biological half-life measured in minutes into one that remains active for 6 to 8 days, maintaining a stable elevation in pulsatile GH secretion and a corresponding rise in IGF-1. Research has examined this compound across models of GH deficiency, body composition, metabolic function, and tissue recovery. What distinguishes it from shorter-acting GHRH analogs is the ability to study sustained, physiologically consistent GH elevation rather than transient peaks followed by rapid clearance. For research protocols where dosing frequency is a key variable, that distinction matters considerably.

CJC-1295 w/DAC: Frequently Asked Questions
What is CJC-1295 with DAC?
CJC-1295 with DAC is a modified analog of GHRH(1-29) that includes a Drug Affinity Complex, a maleimide-lysine linker that binds covalently to serum albumin after injection, extending its half-life from minutes to 6 to 8 days.
What is the difference between CJC-1295 with DAC and without DAC?
CJC-1295 without DAC (also called Modified GRF 1-29) has a half-life of roughly 30 minutes. The DAC modification extends this to 6 to 8 days by enabling serum albumin binding, resulting in sustained GH elevation rather than short pulses.
How does CJC-1295 with DAC affect GH levels?
Research has shown it produces a stable, sustained elevation in pulsatile GH secretion and a corresponding rise in IGF-1 levels, maintained over days from a single injection.
Is CJC-1295 with DAC often combined with other peptides?
Yes. CJC-1295 with DAC is frequently studied alongside Ipamorelin, a selective GH secretagogue that acts on a complementary receptor pathway (GHS-R1a), producing amplified GH output greater than either compound achieves alone.
Is CJC-1295 with DAC for human use?
No. CJC-1295 with DAC from Blackwell BioLabs is sold strictly for laboratory and research purposes. It is not approved for human consumption or therapeutic use.
