What is CJC-1295 with DAC?
CJC-1295 with DAC is a long-acting peptide that signals the pituitary gland to increase the body’s own growth hormone production, which in turn raises IGF-1. The DAC modification is what sets it apart: it allows CJC-1295 to remain active for days rather than producing only a short-lived effect.
Why CJC-1295 with DAC?
Sustained GH Release
Human trials found CJC-1295 can keep growth hormone and IGF-1 elevated for days, rather than creating only a brief increase.
Muscle & Recovery
Growth hormone and IGF-1 are involved in muscle and tissue processes, explaining the interest in CJC-1295 among people focused on training and recovery.
Body Composition
Its effects on the GH/IGF-1 system make CJC-1295 popular with people interested in lean mass, recovery and overall body composition.
Who is CJC-1295 with DAC Popular With?
CJC-1295 with DAC is particularly popular with gym-goers interested in muscle, recovery and body composition who want sustained growth-hormone activity. Its long duration is its main differentiator from shorter-acting growth-hormone-releasing peptides, while its effect comes from encouraging the body to release more of its own growth hormone rather than supplying growth hormone directly.
Research & Evidence
CJC-1295 has direct human research showing sustained increases in growth hormone and IGF-1. However, these studies primarily measured hormone responses rather than outcomes such as muscle gain, fat loss or recovery, so those customer-facing benefits should not be treated as established clinical results.
Human Trials — GH Increased Up to 10-Fold
In two randomised, placebo-controlled human trials, a single administration of CJC-1295 increased average growth hormone concentrations by approximately 2–10 times for six days or longer. IGF-1 increased around 1.5–3 times and remained elevated for 9–11 days, demonstrating the prolonged hormone response created by its long-acting design.
Human Research — Natural GH Pulses Preserved
A separate human study found CJC-1295 increased average growth hormone by 46% and IGF-1 by 45% one week after administration. Importantly, the normal pulsatile pattern of growth-hormone release was preserved, showing that CJC-1295 increased overall GH activity without simply replacing the body’s natural secretion pattern.

Mitchell polvan –
For the last 5 years, I’ve been fighting chronic Lyme and various co-infections. I’ve managed to clear almost all of them, but I was stuck with a persistent, frustrating issue: severely compromised lung capacity and inflammation.
I knew it wasn’t a physical conditioning problem. I actively run, lift, and stay fit. Yet, even just walking fast would trigger wheezing. Doctors couldn’t find anything definitive. I also spent tons of out-of-pocket testing, bc I knew deep down there was underlying tissue damage or inflammation from the infection.
So I decided to pull the trigger on CJC to see if it could help repair the damage. The results were almost immediate, within just a few days, my VO2 max shot up from ~45 to 50 (tracked via apple watch). Also, wheezing reduced drastically, and my lung capacity felt almost entirely restored.
