When people talk about CJC-1295, the first question is almost always: With DAC or without? This difference changes the entire nature of the activity. We'll explain simply.

What is DAC?
DAC stands for Drug Affinity Complex — a molecular attachment that binds to a protein in the blood and significantly extends the duration of activity of CJC-1295.
The key difference: duration of activity
- CJC-1295 with DAC — a long half-life (days). In research this is expressed as a more stable and sustained "level."
- CJC-1295 without DAC (Mod GRF 1-29) — short activity (minutes to an hour), producing a sharp, temporally focused "pulse."
Why does this matter in research?
Growth hormone release in the body is inherently pulsatile (in waves). Therefore, researchers interested in mimicking a natural pattern tend toward the short version (without DAC, usually with Ipamorelin), while those interested in a sustained level examine the DAC version. There is no single "right" one — it depends on the research question.
Frequently asked questions
Which version is more common in combination with Ipamorelin?
Usually the version without DAC. See the article on CJC-1295 + Ipamorelin.
How is it reconstituted?
From powder, using bacteriostatic water andour dilution calculator.
