The CJC-1295 + Ipamorelin blend is a synthetic peptide combination formulated for controlled laboratory and in vitro research applications. It pairs a growth hormone–releasing hormone (GHRH) analogue (CJC-1295) with a growth hormone secretagogue (Ipamorelin) to support studies of pulsatile growth hormone signaling, endocrine pathways, and peptide synergy under standardized conditions.
Peak Science Peptides supplies this blend as a lyophilized powder to maintain structural stability and enable precise reconstitution for diverse experimental workflows. All peptides are pharmaceutical grade and supported by third‑party laboratory analysis for identity, purity (commonly ≥98–99% in comparable products), and contaminant thresholds. This product is intended for research purposes only and is not approved for diagnostic or therapeutic use.
CJC-1295 is a synthetic analogue of growth hormone–releasing hormone designed to extend GHRH half‑life and enhance growth hormone (GH) release via pituitary stimulation. Ipamorelin is a selective growth hormone secretagogue that acts at ghrelin receptors to promote GH pulses with relatively low activity on cortisol or prolactin in preclinical and clinical models.
When combined, CJC-1295 provides a sustained GHRH‑like signal while Ipamorelin contributes complementary, pulse‑like GH release, allowing researchers to examine dual‑pathway modulation of the somatotropic axis. This makes the blend suitable for mechanistic studies of GH dynamics, downstream IGF‑1 signaling, receptor pharmacology, and comparative analyses versus single‑peptide controls.
Research groups evaluating GH‑related pathways rely on consistent peptide quality to limit experimental variability. By offering pharmaceutical‑grade synthesis paired with independent third‑party lab verification, Peak Science Peptides supports reproducible data generation for endocrine, metabolic, and cell‑signaling investigations involving CJC-1295 + Ipamorelin.
Each batch is lot‑tracked and accompanied by analytical documentation so laboratories can align internal quality systems with external supplier specs. This approach helps standardize assay inputs for applications such as receptor binding work, time‑course GH/IGF‑1 studies, and exploratory models of tissue response to GH axis modulation.
Literature and clinical summaries report that CJC-1295 can sustain elevated GH and IGF‑1 levels for several days, while Ipamorelin generates shorter‑acting GH pulses. When used together, sources describe a 3–5‑fold increase in GH release versus single‑agent use, highlighting a synergistic effect on the somatotropic axis. This synergy makes the combination useful for modeling physiological versus supraphysiological GH patterns in experimental systems.
CJC-1295 mimics endogenous GHRH by binding to GHRH receptors on pituitary somatotrophs, triggering cAMP/IP3 signaling and sustained GH synthesis and release. Ipamorelin binds ghrelin receptors (GHS‑R1a), inducing rapid GH pulses; together they generate both prolonged and spike‑like GH patterns in experimental models.
Technical resources recommend storing lyophilized CJC-1295 and Ipamorelin in a dry, light‑protected environment at 2–8°C to optimize shelf life. Once reconstituted, solutions are typically kept refrigerated for a limited period and protected from repeated freeze–thaw cycles to minimize degradation and maintain experimental consistency.
Comparable research‑grade blends on the market report purity levels around or above 98–99% confirmed by reverse‑phase HPLC, with component content verified against labeled claims. Additional third‑party tests often include sterility, endotoxin (LPS) screening, residual TFA checks, and confirmation of molecular identity via mass spectrometry. Peak Science Peptides follows this third‑party lab verification model to provide pharmaceutical‑grade material suitable for demanding research protocols.
