How should Ipamorelin be stored?

In lyophilized powder form, Ipamorelin is stable at room temperature short-term but should be refrigerated (2–8°C) for longer storage and kept away from light and moisture. Once reconstituted, keep refrigerated and use within 30 days. Avoid freeze-thaw cycles.

Is Ipamorelin approved by the FDA?

No. Ipamorelin is not FDA-approved for human use. NextSelf Labs sells Ipamorelin strictly as a research chemical for laboratory research.

What is the purity of your Ipamorelin?

All NextSelf Labs Ipamorelin is manufactured to ≥99% purity and verified by third-party laboratories using HPLC and mass spectrometry. The Certificate of Analysis for every batch is available on this page — match the batch number on your vial to the COA header to verify.

How is Ipamorelin different from CJC-1295?

Both stimulate growth hormone release, but through different receptors. CJC-1295 acts on the GHRH receptor; Ipamorelin acts on the ghrelin receptor. They’re often paired in research because the combined signal is stronger than either alone.

What does 'selective' mean in this context?

Earlier GH secretagogues often raised cortisol, prolactin, and other hormones along with growth hormone. Ipamorelin was designed to stimulate GH release with minimal effect on those other pathways — the 'selective' label refers to that narrow profile.

Do I need a prescription to purchase Ipamorelin?

No. NextSelf Labs sells Ipamorelin as a research chemical for laboratory use only.

About the Peptide

The cleanest signal in the family.

Ipamorelin is a synthetic pentapeptide that mimics ghrelin, the body’s natural growth hormone-releasing signal. Among the secretagogue family, Ipamorelin is the most selective — stimulating GH release without meaningfully affecting cortisol, prolactin, or other hormones that often accompany growth hormone signaling.

That selectivity is why Ipamorelin has become the secretagogue of choice in women’s recovery research. Many earlier peptides in this category produced unwanted hormonal noise. Ipamorelin’s narrow mechanism allows researchers to study GH-related effects without confounding hormonal interference.

Published research has documented Ipamorelin’s role in stimulating pulsatile growth hormone release, supporting recovery and tissue repair, and contributing to the metabolic and body composition effects associated with optimized growth hormone signaling.

Research Applications

Selectivity women’s research has been waiting for.

Hormonal precision matters more for women than for almost any other research population. Ipamorelin’s narrow mechanism is what makes it the secretagogue of choice.

Pulsatile GH Release

Ipamorelin stimulates growth hormone release in pulses that more closely match the body’s natural rhythm, without the sustained elevation that disrupts feedback signaling.

Recovery & Repair

Studies have documented Ipamorelin’s role in supporting the cellular processes underlying tissue recovery, particularly in research populations focused on age-related decline.

Hormonal Specificity

Unlike earlier secretagogues, Ipamorelin has minimal effects on cortisol or prolactin — a profile especially relevant to research populations sensitive to hormonal fluctuations.
