CJC-1295 is a synthetic peptide analog of growth-hormone-releasing hormone (GHRH). It is designed to stimulate the pituitary gland to release growth hormone. It is sold as a research chemical and is not an FDA-approved medicine.

What is the difference between CJC-1295 with DAC and without DAC?

CJC-1295 'with DAC' includes a Drug Affinity Complex that binds to albumin in the blood, greatly extending its reported half-life to several days. The 'without DAC' version (often called Modified GRF 1-29) is much shorter-acting. The DAC version aims for sustained GH elevation rather than short pulses.

What is CJC-1295 studied for?

Early pharmacology research examined CJC-1295 for its ability to raise growth hormone and IGF-1 levels. It is not an approved therapy, and human safety and efficacy data are limited.

Is CJC-1295 FDA-approved?

No. CJC-1295 is not FDA-approved for any use and is sold only as a research chemical. Several peptide growth hormone secretagogues have been flagged by the FDA as unsuitable for compounding.

Is CJC-1295 banned in sports?

Yes. As a growth-hormone-releasing peptide, CJC-1295 is prohibited at all times in sport by the World Anti-Doping Agency.

Why is CJC-1295 often discussed with ipamorelin?

They work through complementary pathways — CJC-1295 mimics GHRH while ipamorelin acts on the ghrelin receptor — so they are frequently mentioned together in research literature. Combining substances raises unknowns and is strictly a clinical decision.

How is CJC-1295 reconstituted?

Lyophilized CJC-1295 is typically reconstituted with bacteriostatic water added slowly down the vial wall and gently swirled until clear. See the steps below and our reconstitution guide.

CJC-1295 dosage

CJC-1295 comes in 5 mg and 10 mg vials. Pick your vial to see exactly how much bacteriostatic water to add and how many insulin units to draw. Reconstitution math and unit conversions for the 5 mg and 10 mg vials. CJC-1295 has no validated human dose; the figures shown are community-reported, with the DAC human study cited for reference.

Calculate for your vial

Enter the mg on your CJC-1295 vial, the bacteriostatic water you added, and your target dose — it works out the exact units to draw on a U-100 insulin syringe, for whatever you personally have.

Personalize by body weight & height

CJC-1295 · tailored to you

Optional

Growth-hormone release scales with body size, so bigger people tend to sit toward the higher end. The usual range is about 100–300 mcg; the numbers below estimate that for your weight.

Typical flat community dose: 100 mcg – 300 mcg per injection.

GH response is weight-related in research, but there is no validated per-kg use instruction — this is an anecdotal estimate kept inside the normal ~100–300 mcg range, not a recommendation. Many people just use a flat amount.
