CJC-1295 vs Sermorelin

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

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)

Molecular Weight

3647.28 Da

CAS Number

863288-34-0

Research Categories

Growth Hormone Axis

Routes of Administration

Sermorelin

GHRH(1-29) · GRF 1-29 NH2 · Geref

Approved

Sermorelin is a synthetic analog of the first 29 amino acids of endogenous growth hormone-releasing hormone (GHRH). It stimulates the pituitary to produce and secrete growth hormone in a pulsatile, physiologic manner. FDA-approved for GH deficiency in children, it is extensively researched in adults for body composition, sleep quality, and age-related GH decline.
