What is CJC-1295 + Ipamorelin?

CJC-1295 + Ipamorelin is a dual-peptide formulation combining a growth hormone-releasing hormone (GHRH) analogue with a selective growth hormone secretagogue receptor (GHSR/ghrelin receptor) agonist. These two peptides operate through complementary mechanisms: CJC-1295 (without DAC) stimulates GH release by binding GHRH receptors on pituitary somatotrophs and amplifying the baseline GH pulse, while ipamorelin activates the ghrelin receptor to initiate a separate GH release signal. When administered together, research indicates a synergistic amplification of GH pulsatility that exceeds the additive effects of either peptide alone. This synergy was characterized in studies examining GHRH-GHRP co-administration, where combined protocols produced GH peaks 2-3 times greater than single-agent protocols (Bowers et al., Endocrinology). Ipamorelin is distinguished among ghrelin mimetics by its high selectivity for GH release without significantly elevating cortisol, prolactin, or ACTH levels, as demonstrated in clinical studies (Raun et al., European Journal of Endocrinology, 1998). CJC-1295 without DAC has a half-life of approximately 30 minutes, producing acute GH pulses rather than sustained elevation. Compared to GHRP-6, which broadly activates ghrelin receptors causing appetite stimulation, ipamorelin offers cleaner GH release profiles. Store lyophilized powder at -20C; reconstitute with bacteriostatic water and refrigerate at 2-8C for up to 28 days. This combination is widely studied by endocrinology research labs, sports medicine institutions, and body composition research centers investigating optimized GH secretagogue protocols.

CJC-1295 + Ipamorelin Research Applications

In published and preclinical research, CJC-1295 + Ipamorelin has been studied across the following areas:

CJC-1295 + Ipamorelin in Research: Reconstitution & Study Concentrations

CJC-1295 + Ipamorelin is supplied as a lyophilized powder. For laboratory research it is reconstituted with bacteriostatic or sterile water; the solvent volume sets the working concentration. Published studies select concentrations specific to the assay or model system — there is no human dose, as CJC-1295 + Ipamorelin is not approved for human use. Researchers should reference the primary literature for the model in question and document the exact lot COA.

Worked example: a 10mg vial reconstituted with 2 mL of bacteriostatic water yields 5.00 mg/mL.

CJC-1295 + Ipamorelin — Frequently Asked Questions

What is CJC-1295 + Ipamorelin and how does it work?

This combination pairs two distinct growth hormone secretagogues that work through complementary mechanisms. CJC-1295 (without DAC) is a modified GHRH analogue that stimulates GH release from pituitary somatotrophs via the GHRH receptor. Ipamorelin is a selective ghrelin receptor (GHS-R1a) agonist. Together, they amplify GH pulsatility through dual-pathway stimulation while maintaining selectivity — ipamorelin does not significantly affect cortisol or prolactin levels.

What research has been done on CJC-1295 + Ipamorelin?

CJC-1295 research published in the Journal of Clinical Endocrinology & Metabolism demonstrated sustained GH and IGF-1 elevation with a favorable safety profile. Ipamorelin studies (European Journal of Endocrinology) showed selective GH release without significant hunger, cortisol, or prolactin side effects. The combination has been studied in preclinical models for synergistic GH amplification, with results suggesting greater GH AUC than either peptide alone.

How does CJC-1295 + Ipamorelin compare to GHRP-6?

The key advantage of ipamorelin over GHRP-6 is selectivity. GHRP-6 activates ghrelin receptors broadly, causing significant increases in appetite, cortisol, and prolactin. Ipamorelin is among the most selective GH secretagogues, stimulating GH release with minimal impact on other hormones. When combined with CJC-1295, it provides a cleaner research model for studying GH-specific effects without confounding hormonal variables.

What is the recommended reconstitution protocol for CJC-1295 + Ipamorelin?

For this 10mg vial (5mg CJC-1295 + 5mg Ipamorelin), add 2 mL of bacteriostatic water to yield a concentration of 5.0mg/mL total. Draw 10 units on a 1mL insulin syringe for a 250 mcg dose of each peptide. Inject BAC water slowly along the inner vial wall — do not shake. Allow the powder to dissolve fully (2–5 minutes). Administer AM and PM. Use 5 days on, 2 days off. Refrigerate reconstituted solution at 2–8°C and use within 30 days.

Is CJC-1295 + Ipamorelin legal to buy for research?

CJC-1295 + Ipamorelin is sold in the United States as a research chemical for laboratory and in-vitro use only. It is not approved by the FDA for human use and is not sold for human consumption. Researchers are responsible for compliance with all applicable federal, state, and institutional regulations.

How is CJC-1295 + Ipamorelin reconstituted for research use?

CJC-1295 + Ipamorelin ships as a lyophilized (freeze-dried) powder and is reconstituted with bacteriostatic or sterile water before use in research. The volume of solvent added determines the working concentration — use the Elyte reconstitution calculator to derive the exact concentration for a given vial size and solvent volume.

Does CJC-1295 + Ipamorelin come with a Certificate of Analysis?

Yes. Every batch of CJC-1295 + Ipamorelin from Elyte Peptides ships with a third-party Certificate of Analysis (COA) documenting identity and HPLC purity (≥98%), so research results can be traced to a verified lot.
