What is Ipamorelin?
Ipamorelin is a pentapeptide and one of the most selective growth hormone secretagogues (GHS) available for research. It works by binding to ghrelin receptors (GHS-R1a) in the pituitary gland, stimulating the release of growth hormone without significantly affecting cortisol, prolactin, or ACTH levels — making it notably cleaner than other GHS peptides like GHRP-6. Ipamorelin produces a strong, clean pulse of growth hormone that mimics natural physiological GH release. It is often combined with a GHRH analog like CJC-1295 for synergistic effects.
Key Research Benefits
Documented effects observed in preclinical and clinical studies on Ipamorelin. See all Growth Hormone Secretagogues peptides for comparison.
Common Stacks
Ipamorelin is frequently combined with the following peptides for synergistic effects. Click any peptide to compare profiles before deciding.
The gold-standard GH stack - Ipamorelin provides a clean GH pulse while CJC-1295 extends the release window for sustained elevation.
Sermorelin (GHRH) + Ipamorelin (GHRP) is the synergistic dual-mechanism GH stack that produces 8-15x more GH than either alone.
Stacked for improved sleep quality, since Ipamorelin's GH release is highest during deep sleep stages.
Sermorelin (GHRH) combined with Ipamorelin (GHRP) produces synergistic GH release greater than either compound alone.
Side Effects & Risks
Adverse effects reported in the research literature. All data sourced from preclinical and clinical study reports.
Dosing Data from the Literature
Doses referenced below are sourced from published preclinical and clinical studies. Use the peptide dose calculator to convert these values to injection volume.
Typical research dosing: 200–300 mcg per injection, administered 1–3 times daily. Most common protocol is 2x daily (morning and evening) or pre-bedtime for maximum GH pulse during sleep. Often stacked with CJC-1295 DAC or Mod GRF 1-29.
Administration in Research Settings
Standard reconstitution and administration methodology for laboratory research use.
Reconstitute with bacteriostatic water and administer via subcutaneous injection. Inject on an empty stomach or 2 hours after a meal for best results (high insulin blunts GH release). Inject 30–60 minutes before bed to align with natural GH pulses. Rotate injection sites. Standard cycle: 8–12 weeks on, then break.
