Description

What is CJC-1295 / Ipamorelin?

The CJC-1295/Ipamorelin blend combines two of the most widely studied growth hormone peptides in preclinical and clinical research: CJC-1295 (a synthetic GHRH analog) and Ipamorelin (a selective ghrelin receptor agonist).

These two peptides work through different but complementary receptor pathways. CJC-1295 acts as a GHRH receptor agonist on the pituitary gland, amplifying the growth hormone release signal. Ipamorelin acts as a ghrelin/GHS receptor agonist, inducing growth hormone release through a separate pathway. When combined, they stimulate GH release through both the “amplifier” (GHRH) and “inducer” (GHRP) mechanisms simultaneously.

This dual-pathway approach is one of the most commonly studied combinations in growth hormone research because it promotes stronger, more consistent pulsatile GH release than either peptide alone, while Ipamorelin’s high selectivity helps avoid unwanted elevations in cortisol, prolactin, or other hormones.

Neither component is approved by the FDA for any medical use. This blend is sold strictly for laboratory and research purposes only.

Research Applications

Areas of Investigation

Synergistic GH

Dual-Pathway GH Release

Combines GHRH receptor agonism (CJC-1295) with ghrelin receptor agonism (Ipamorelin) to stimulate growth hormone release through two complementary mechanisms simultaneously.

GH Pulsatility

Pulsatile GH Signaling

Studied for promoting natural pulsatile growth hormone release patterns, mimicking the body's physiological GH secretion rhythm more closely than either peptide alone.

IGF-1

IGF-1 Axis Research

Investigated for sustained elevations in IGF-1 levels through enhanced GH secretion, supporting downstream anabolic and regenerative signaling pathways.

Selectivity

Selective Endocrine Signaling

Ipamorelin's high receptor selectivity helps maintain clean GH stimulation without significant increases in cortisol, prolactin, or aldosterone — a key advantage over less selective secretagogues.

Frequently Asked Questions

Common questions about CJC-1295 / Ipamorelin research

What is the CJC-1295/Ipamorelin blend?

This blend combines CJC-1295 (a GHRH analog) with Ipamorelin (a selective ghrelin receptor agonist). They target two different receptor pathways that both lead to growth hormone release, producing a synergistic effect when used together.

Why combine CJC-1295 and Ipamorelin instead of using them separately?

CJC-1295 amplifies the GH release signal through the GHRH receptor, while Ipamorelin induces GH release through the ghrelin receptor. Together, they activate both the "amplifier" and "inducer" pathways, which research suggests produces stronger and more consistent GH pulsatility than either peptide alone.

Is this blend the same as CJC-1295 with DAC?

No. This blend uses CJC-1295 without DAC (also called Modified GRF 1-29), which has a shorter half-life and produces more physiological pulsatile GH release. CJC-1295 with DAC is a separate product with an extended half-life of 6-8 days due to albumin binding.

How should this blend be stored?

Lyophilized powder should be stored below -18°C, away from light and moisture. Once reconstituted with bacteriostatic water, refrigerate at 2-8°C and use within 28 days.

Is the CJC-1295/Ipamorelin blend FDA approved?

No. Neither CJC-1295 nor Ipamorelin is approved by the FDA. Both are prohibited by WADA under the S2 category. This blend is sold for laboratory and research purposes only.
