The GH Synergy Stack: CJC-1295 (No DAC) + Ipamorelin

The gold-standard pulsatile growth hormone secretagogue protocol preserving natural pituitary feedback.

CJC-1295 (No DAC)(GHRH Receptor Agonist (The Gate Opener))

Ipamorelin(Selective Ghrelin / GHS-R1a Agonist (The Trigger))

Protocol Overview

The pairing of CJC-1295 (Mod GRF 1-29) and Ipamorelin is the most widely validated growth hormone secretagogue protocol in anti-aging and sports science literature. By combining a GHRH analog (which opens the pituitary GH release gate) with a selective GHRP (which triggers the release pulse), this dual stack produces up to a 5-fold amplification in GH secretion while strictly preserving somatostatin feedback loops and avoiding prolactin/cortisol spikes.

Multi-Pathway Synergy Breakdown

Step 01Anti-Aging

CJC-1295 (No DAC)

GHRH Receptor Agonist (The Gate Opener)

Binds GHRH receptors on pituitary somatotrophs, increasing cAMP and priming the intracellular pool of growth hormone for release.

Research Dosage:100–150 μg SC at bedtime

Step 02Anti-Aging

Ipamorelin

Selective Ghrelin / GHS-R1a Agonist (The Trigger)

Triggers calcium exocytosis of GH without binding to serotonin, acetylcholine, or opioid receptors, ensuring zero elevation of cortisol, prolactin, or aldosterone.

Research Dosage:100–200 μg SC at bedtime

Scientific Mechanism of Synergy

Administering a GHRH analog alone or a GHRP alone results in modest GH release. When administered simultaneously, the intracellular cAMP (GHRH) and IP3/DAG/calcium (GHRP) cascades synergize, generating a massive physiological GH pulse identical to young adult nocturnal peaks.

Key Research Benefits

Up to 5x increase in natural endogenous GH pulse amplitude
Elevation of circulating IGF-1 without exogenous pituitary suppression
Enhanced slow-wave (deep) sleep architecture and cellular repair
No stimulation of appetite (unlike GHRP-6) and no cortisol elevation

Protocol Administration & Timing

Dosing Timing:Administered at night before sleep on an empty stomach (at least 2 hours post-meal).

Cycle Duration:Typical protocols evaluate 5 days on / 2 days off or 8–12 week cycles.

Handling:Insulin and carbohydrates blunt GH release; always ensure blood glucose and insulin levels are baseline during dosing.

Important Research Safety Notes

• Transient head rush or mild facial flushing may occur for 2–5 minutes post-injection due to mild vasodilation.
• Contraindicated in active malignancy or proliferative retinopathy.

Frequently Asked Questions

Why must CJC-1295 and Ipamorelin be taken on an empty stomach?▼

Circulating blood glucose and insulin stimulate somatostatin release from the hypothalamus. Somatostatin is the body's natural GH-inhibiting hormone and will blunt the pituitary response to secretagogues.
