CJC-1295 / Ipamorelin

The #1 recommended peptide combo for women over 40. Restores natural growth hormone pulsing to support sleep quality, body composition, skin health, and perimenopause brain fog.

EvidenceCategory 1 / Category 2

Mechanism of Action

CJC-1295 is a growth hormone-releasing hormone (GHRH) analog that extends GH release duration, while Ipamorelin is a selective growth hormone secretagogue that triggers GH pulses without affecting cortisol or prolactin. Together, they restore the natural pulsatile GH pattern that diminishes with age (somatopause), providing synergistic effects on sleep, body composition, skin, and recovery.

Why It Matters for Women

The somatopause — decline in growth hormone production — accelerates during perimenopause and is not addressed by HRT. This is the key framing: "HRT addresses sex hormones. CJC-1295/Ipamorelin addresses the growth hormone decline that estrogen replacement alone does not cover." Women over 40 report improvements in sleep quality, reduced brain fog, improved body composition, and better skin quality. It is the single most-prescribed peptide combo in integrative women's health clinics.

Key Finding: The most-prescribed peptide combo for women over 40. Addresses the growth hormone decline (somatopause) that HRT does not cover.

Side Effects & Safety

Common side effects include injection site reactions, water retention, tingling/numbness in extremities, and increased hunger. Ipamorelin is considered one of the cleanest GH secretagogues because it does not significantly raise cortisol or prolactin. CJC-1295 DAC (with Drug Affinity Complex) has a longer half-life but may cause more sustained side effects. Note: Ipamorelin is currently Category 2.

Frequently Asked Questions

Why combine CJC-1295 with Ipamorelin?

CJC-1295 extends the duration of GH release while Ipamorelin triggers clean GH pulses without raising cortisol or prolactin. Together they mimic the natural pulsatile GH pattern more effectively than either peptide alone.

Is Ipamorelin Category 2?

Yes — Ipamorelin is currently classified as Category 2 by the FDA, meaning it faces additional regulatory scrutiny. CJC-1295 is Category 1. The combination product availability may vary by vendor. Check current status before purchasing.

What results can women over 40 expect?

Commonly reported benefits include improved sleep quality (especially deep sleep), reduced brain fog, improved skin firmness and hydration, better body composition, and enhanced recovery from exercise. Results typically become noticeable within 4-8 weeks.
