Best GH Peptide Stacks — Ipamorelin + CJC-1295 Protocol & Dosing Guide

How to combine GH peptides for maximum GH pulse amplitude — the science behind GHRH + GHRP synergy and the best-studied GH research stacks.

By Dr. Jordan ReevePublished 10 min read

Why Stack GH Peptides?

The synergistic effect of combining GHRH analogues with GH secretagogues (GHRPs) produces GH pulses dramatically larger than either compound alone. Understanding this synergy requires knowing how the GH axis is regulated.

The GH Axis: A Two-Signal System

GH release from the pituitary is controlled by competing signals:

  • GHRH (stimulatory) — released from the hypothalamus to trigger GH release
  • Somatostatin (inhibitory) — released to inhibit GH release and maintain pulsatile rhythms

    • GHRH analogues (CJC-1295, Sermorelin) mimic GHRH's stimulatory signal. GHRPs (Ipamorelin, GHRP-2) both activate GHS-R1a receptors AND suppress somatostatin release.

    Combining both creates synergy: increased stimulation + decreased inhibition = exponentially larger GH pulse.

    The Top Stacking Protocols

    Protocol 1: [Ipamorelin](/products/ipamorelin-10mg) + [CJC-1295 No DAC](/products/cjc-1295-no-dac-5mg)

    The Classic Clean Protocol

    The most studied combination. Ipamorelin's selectivity (no cortisol/prolactin elevation) paired with CJC-1295 No DAC's pulsatile GHRH mimicry creates a natural-rhythm GH release.

    Protocol 2: [GHRP-2](/products/ghrp-2-10mg) + [CJC-1295 No DAC](/products/cjc-1295-no-dac-5mg)

    High Amplitude Protocol

    GHRP-2 produces a larger GH pulse than Ipamorelin but with some cortisol elevation. Combined with CJC-1295 No DAC, this creates very high GH peaks.

    Protocol 3: [Ipamorelin](/products/ipamorelin-10mg) + [CJC-1295 With DAC](/products/cjc-1295-with-dac-10mg)

    Long-Acting Protocol

    CJC-1295 with DAC's 6-8 day half-life allows once or twice weekly administration of the GHRH component, combined with daily Ipamorelin. Provides sustained elevated GH throughout the week.
