CJC-1295 DAC
Also known as: CJC-1295 with DAC · DAC:GRF
A long-acting growth-hormone-releasing hormone (GHRH) analog whose Drug Affinity Complex (DAC) extends its half-life, discussed for prompting the body’s own growth-hormone release over a much longer window than the no-DAC form.

Proposed mechanisms / pathways
What is CJC-1295 DAC?
CJC-1295 DAC is the long-acting version of the CJC-1295 growth-hormone-releasing hormone (GHRH) analog. The "DAC" stands for Drug Affinity Complex — a chemical modification that lets the peptide bind to albumin in the blood, dramatically slowing its clearance. Where the no-DAC form (Mod GRF 1-29) acts for roughly half an hour, the DAC variant is engineered to stay active for days, which is why it is discussed in the context of a far less frequent dosing schedule.
How it is thought to work
Like other GHRH analogs, CJC-1295 DAC is thought to bind the GHRH receptor on the pituitary and prompt the gland to release more of the body’s own growth hormone. The DAC modification is reported to extend how long that signal persists, so rather than producing a single sharp pulse it is discussed as maintaining a more sustained elevation. Because a GHRH analog and a GH secretagogue act through complementary pathways, it is often paired with a peptide such as Ipamorelin.

CJC-1295 DAC is a research peptide and is not an approved medication for general human use. Nothing here is a recommendation, dose, or medical claim. Consult a qualified healthcare provider and follow the laws in your area.
Tracking CJC-1295 DAC in LynkDose
Because the DAC form is long-acting, the most useful habit is logging each injection date and the weekly cadence rather than thinking in daily doses. If you pair it with another peptide, log each compound separately. The effects people look for — recovery, sleep, and body composition — build slowly, so let objective metrics from Apple Health accumulate. In LynkDose the value comes from the multi-week trend, which is exactly what a tracker is built to surface.
Commonly discussed for
- Supporting the body’s natural growth-hormone release on an infrequent schedule
- Maintaining a more sustained GH signal versus short-acting forms
- Recovery and body-composition goals over longer timeframes
Often stacked: Often paired with a GH secretagogue such as Ipamorelin, combining a long-acting GHRH analog with a GH-releasing peptide.
How to track CJC-1295 DAC in LynkDose
Because the DAC form is long-acting, log each injection date rather than daily doses, and note the weekly cadence. Watch recovery, sleep, and body-composition trends accumulate over weeks, since effects build slowly.
