How should CJC-1295 / Ipamorelin be stored?

In lyophilized powder form, CJC-1295 / 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 CJC-1295 / Ipamorelin approved by the FDA?

No. CJC-1295 / Ipamorelin is not FDA-approved for human use. NextSelf Labs sells CJC-1295 / Ipamorelin strictly as a research chemical for laboratory research.

What is the purity of your CJC-1295 / Ipamorelin?

All NextSelf Labs CJC-1295 / 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.

What does 'without DAC' mean?

DAC stands for Drug Affinity Complex, a modification that extends CJC-1295’s half-life from minutes to days. The 'without DAC' formulation produces shorter, pulsatile GH release that more closely mirrors the body’s natural rhythm — the form preferred in most research protocols.

Why are these two peptides combined?

CJC-1295 and Ipamorelin act on different receptors in the growth hormone pathway. Their combined use produces a stronger and more reliable GH pulse than either peptide alone, which is why the pairing dominates the research literature.

Do I need a prescription to purchase this blend?

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

About the Peptide

A pairing studied for how the body changes.

CJC-1295 and Ipamorelin are two of the most-studied peptides in the growth hormone secretagogue family. When paired, they target the same physiological pathway through two different mechanisms — a combination that has made this blend one of the most widely researched approaches in growth hormone modulation.

Growth hormone naturally declines with age, beginning in the late twenties and accelerating through the decades that follow. For women, this decline overlaps with the hormonal shifts of perimenopause, often producing the cluster of symptoms — slower recovery, changes in body composition, sleep disruption — that prompt research into pulsatile GH support.

Published research has documented this peptide pairing’s role in stimulating endogenous growth hormone release, supporting lean tissue maintenance, and improving the depth and architecture of slow-wave sleep. The ‘without DAC’ formulation produces shorter, more pulsatile GH release patterns that more closely mirror the body’s natural rhythms.

Research Applications

Where pulsatile rhythm meets women’s biology.

Hormonal shifts in women rarely follow a straight line. CJC-1295 and Ipamorelin have been studied for their ability to support growth hormone release in patterns that more closely match the body’s natural pulses.

Body Composition

Research suggests this blend supports lean tissue maintenance and influences how the body manages fat distribution — areas of particular interest to women navigating perimenopausal changes in body composition.

Sleep Quality

Studies of growth hormone secretagogues consistently report improvements in slow-wave sleep depth and architecture, with downstream effects on next-day recovery and cognitive function.

Recovery & Vitality

By supporting the body’s natural pulsatile growth hormone release, the blend has been studied for broader effects on tissue recovery, skin integrity, and the markers women associate with vitality at any age.
