Ipamorelin vs CJC-1295

Side-by-side comparison of research status, mechanisms, pharmacokinetics, and administration routes.

Ipamorelin

NNC 26-0161

Preclinical

Ipamorelin is a selective growth hormone secretagogue and ghrelin receptor agonist. Unlike other GHRPs, it stimulates GH release with high selectivity — producing minimal cortisol, ACTH, or prolactin elevation. It is among the most studied GHRPs for its clean GH pulse profile, making it a preferred research peptide for GH axis studies with reduced side effect concern.

CJC-1295

CJC-1295 with DAC · DAC:GRF

Preclinical

CJC-1295 is a modified GHRH analog with a Drug Affinity Complex (DAC) that binds to serum albumin, dramatically extending its half-life compared to native GHRH. It produces sustained elevation of GH and IGF-1 levels over days rather than hours. Research focuses on body composition improvements, muscle growth, and fat loss through prolonged GH axis stimulation.

Research Status

Preclinical Research

Half-Life

6–8 days (due to DAC albumin binding)
