CJC-1295

Also known as: CJC-1295 DAC, CJC-1295 no-DAC, Mod GRF 1-29

CJC-1295 is a synthetic growth-hormone-releasing hormone (GHRH) analog studied for stimulating growth-hormone release. It exists in forms with and without DAC (Drug Affinity Complex), which substantially changes its duration of action; the DAC form is much longer-acting. It is widely regarded as a research peptide and this entry is informational, not a recommendation to use the compound.

Questions, answered.

What is CJC-1295?
CJC-1295 is a synthetic growth-hormone-releasing hormone (GHRH) analog studied for stimulating growth-hormone release. It exists in forms with and without DAC (Drug Affinity Complex), which substantially changes its duration of action; the DAC form is much longer-acting. It is widely regarded as a research peptide and this entry is informational, not a recommendation to use the compound.
What is CJC-1295's half-life?
CJC-1295's elimination half-life is approximately 30 hours, per published pharmacokinetic data. After about five half-lives (~150 hours (about 6.3 days)), a single dose is roughly 97% eliminated. Individual clearance varies.
Is CJC-1295 the same as CJC-1295 DAC or CJC-1295 no-DAC or Mod GRF 1-29?
CJC-1295 DAC and CJC-1295 no-DAC and Mod GRF 1-29 are other names associated with CJC-1295.
What do people log alongside CJC-1295?
People tracking this research compound often log injection-site tolerance, sleep, and recovery-related observations. Peptilot has one-tap logging for doses, side effects, weight, and injection sites, so patterns show up in your own record.
