What it is

CJC-1295 is a synthetic analog of growth hormone-releasing hormone (GHRH). It has been studied in the context of growth hormone secretion and is available in two forms: with Drug Affinity Complex (DAC) for extended duration, and without DAC (also called Modified GRF 1-29) for shorter activity. It is discussed in communities focused on growth hormone optimization, body composition, and recovery.

Published research

CJC-1295 has been studied in human clinical trials evaluating its effects on growth hormone and IGF-1 levels. Published pharmacokinetic studies have characterized its half-life in both DAC and non-DAC forms. Research has examined its potential in the context of growth hormone deficiency and body composition. The DAC form demonstrated sustained GH elevation over several days in published studies.

Community discussion often focuses on combining CJC-1295 (no DAC) with growth hormone-releasing peptides such as ipamorelin.

What the terms on this page mean8 terms
analog
A molecule built to copy a natural one with a deliberate change, usually to make it last longer or bind more tightly.
GH
Growth hormone, released by the pituitary gland, involved in growth and tissue repair.
GHRH
Growth hormone-releasing hormone, the signal that tells the pituitary to release GH.
clinical trial
A study that tests something in people under a written plan, with results recorded.
IGF-1
Insulin-like growth factor 1, made largely in the liver in response to GH, and the marker most GH studies measure.
pharmacokinetics
How fast the body absorbs a substance, where it goes, and how it clears it out.
half-life
The time it takes for a drug's concentration in the blood to fall by half. It does not, by itself, determine a dosing schedule.
peptide
A short chain of amino acids, the building blocks of proteins.

What that means
These substances are not eligible for the policy that applies to substances in category 1. FDA would consider taking action against a compounder for compounding drug products with this bulk drug substance under its general enforcement policies.

About this page

Reviewed 2026-08-11. This page reports what published studies and FDA documents say. It carries no dose, cycle length or stack, and it does not tell you whether a substance is appropriate for you. Side-effect reports circulating on forums are self-reported rather than measured, so they are not republished here.
