Researchers buy CJC-1295 because it is a widely used tool for studying the growth hormone (GH) system. It is a man-made copy of Growth Hormone Releasing Hormone (GHRH). It binds the GHRH receptor on the pituitary gland and raises GH output for a longer time than natural GHRH.[1] It is the base of the popular CJC-1295 + Ipamorelin pairing, which combines two ways of boosting GH.
This long-lasting action sets it apart from plain GHRH copies. It is useful for long-term GH/IGF-1 studies, body composition research, and recovery models.
Benefits & Uses
It is mainly used to study GH and IGF-1 over time.[1] Common research areas include:
Long-lasting GH and IGF-1 stimulation studies Lean body mass and muscle-growth models Fat metabolism and body composition research Sleep pattern and deep-sleep studies Recovery, repair, and anabolic hormone research Albumin-binding (DAC) pharmacokinetic studies
How It Works
CJC-1295 works by switching on the GHRH receptor (GHRHR) on pituitary cells, which makes them release growth hormone in pulses. In studies in healthy adults, a single dose raised GH and IGF-1 for several days.[1] The DAC version attaches to the body’s own albumin, forming a slow-release store that keeps it active over days. This raises baseline GH and the IGF-1 it triggers — both key drivers of growth and fat use.

Canada FAQs
What is the difference between CJC-1295 with DAC and without DAC?
The difference is half-life. CJC-1295 with DAC has a Drug Affinity Complex that binds albumin, stretching its half-life to about 6–8 days. Without DAC (also called Modified GRF 1-29), the half-life is about 30 minutes, so research protocols dose it more often.[1]
Is CJC-1295 often combined with Ipamorelin?
Yes. CJC-1295 triggers GH release through the GHRH receptor, while Ipamorelin works on the ghrelin receptor (GHSR). Used together they make a stronger GH pulse — a common research pairing. See our CJC-1295 + Ipamorelin Blend.
What purity is Reviv Peptides CJC-1295?
≥99% purity, confirmed by third-party HPLC. A Certificate of Analysis is available on request.
Reconstitution & Dosing Guide
How to Reconstitute
Add 3.0 mL of bacteriostatic water to the vial. Aim the water slowly down the inside wall of the vial — do not spray it straight onto the powder. Swirl gently until it fully dissolves; do not shake. This gives about 3.33 mg/mL. Store the mixed vial at 4 °C and use within 28 days.
Low Starting Amount
Amount per injection: 100 mcg — 3 units (0.03 mL) on a U-100 insulin syringe Frequency: Once daily, under the skin (at bedtime) Cycle length: 8–12 weeks
Increase to 250–300 mcg by weeks 7–12 as tolerated.
