What exactly is in this CJC-1295 / Ipamorelin vial?

Each 10 mg vial holds two synthetic peptides — 5 mg of CJC-1295 and 5 mg of Ipamorelin — co-lyophilised together. CJC-1295 is a modified GHRH analog and Ipamorelin is a selective growth-hormone secretagogue. They're paired because they hit two different receptors that both feed into growth-hormone release. This material is for laboratory research use only, not for human or veterinary use.

What has research shown about combining the two?

In preclinical work each peptide raises growth hormone on its own, and together they produce a larger, longer release than either alone. Ipamorelin is noted in studies for firing that pulse without pushing up cortisol or prolactin, which is why it's considered selective. CJC-1295's design stretches the signal out over days rather than minutes. All of this is model-based research, not evidence of any human effect.

Is CJC-1295 / Ipamorelin FDA approved?

No. Neither CJC-1295 nor Ipamorelin is an FDA-approved drug, and the combination is not approved for any use. They are investigational peptides studied in laboratory and preclinical settings. The material sold here is strictly for in-vitro and laboratory research use only.

How does this differ from CJC-1295 with DAC?

The CJC-1295 studied in this pairing is typically the no-DAC form (also called Mod GRF 1-29), which clears faster and pairs well with a pulsatile secretagogue like Ipamorelin. The DAC (drug-affinity complex) version binds albumin and lasts much longer, giving a flatter, extended signal. Researchers pick between them depending on whether they want to model natural pulses or a sustained elevation.

What's the molecular makeup of each peptide?

Ipamorelin is a pentapeptide with the formula C38H49N9O5 and a molecular weight of about 711.85 g/mol. CJC-1295 (no DAC) is a 29-amino-acid GHRH analog with a molecular weight near 3367.9 g/mol. The certificate of analysis for your lot states the exact salt form and corresponding weight where applicable.

How CJC-1295 / Ipamorelin works

The pair is studied to act through two complementary receptors that together shape how much growth hormone gets released and for how long.

GHRH receptorCJC-1295

CJC-1295 mimics growth-hormone-releasing hormone, binding the GHRH receptor on the pituitary to prompt and prolong growth-hormone output in preclinical models.

Ghrelin receptorGHSR agonist

Ipamorelin activates the ghrelin/GH-secretagogue receptor to trigger a sharp growth-hormone pulse, a route studied for its selectivity.

Pulse synergycombined signal

Acting on the two receptors at once is studied to produce a larger, cleaner growth-hormone pulse than either peptide manages alone.
