Ipamorelin is a research compound. It is not approved by the FDA or any regulatory body for human use. This article is for educational and informational purposes only. Nothing here constitutes medical advice. Consult a qualified physician before considering any peptide use.
Ipamorelin (Ipamorelin) is a Growth Hormone Secretagogue (GHS) / Ghrelin mimetic. Synthetic pentapeptide derived from GHRP-1, engineered for selective GH release. It is researched for growth hormone release, improved sleep, fat loss, muscle recovery, bone density support. Common dosages range from 200-300 mcg administered 2-3 times daily.
What Is Ipamorelin?
Ipamorelin (Ipamorelin) is a Growth Hormone Secretagogue (GHS) / Ghrelin mimetic. Synthetic pentapeptide derived from GHRP-1, engineered for selective GH release. Also known as Ipamorelin, IPA, it has been studied for its potential effects on growth hormone release, improved sleep, fat loss, muscle recovery, bone density support.
The most selective GH secretagogue available — the only GHRP that doesn't meaningfully raise cortisol, prolactin, or appetite at therapeutic doses, making it the safest entry point for GH optimization. In the research community, Ipamorelin has gained attention for its distinctive profile.
How Does Ipamorelin Work?
Ipamorelin selectively stimulates GH release by mimicking ghrelin at the GHS-R receptor on pituitary somatotrophs. Unlike other GHRPs (GHRP-2, GHRP-6, Hexarelin), it does not significantly increase cortisol, prolactin, or ACTH at therapeutic doses — making it the cleanest GH secretagogue available with the fewest hormonal side effects.
This multi-pathway activity helps explain why Ipamorelin shows potential across several different applications.
What Does the Research Say About Ipamorelin?
Phase II clinical trials confirm selective GH release without significant effects on cortisol or prolactin. Demonstrated the most favorable side-effect profile of any growth hormone secretagogue in direct comparisons.
Researchers should consult the latest peer-reviewed literature for the most current findings.
What Is the Recommended Ipamorelin Dosage?
Standard Ipamorelin dosing: 200-300 mcg, administered 2-3 times daily via subcutaneous injection.
Half-life: approximately 2 hours. Cycle length: 8-12 weeks, often stacked with CJC-1295.

Open Calculator →What Are the Side Effects of Ipamorelin?
Minimal side effects compared to other GH secretagogues. Mild headache, light-headedness, or injection site reactions possible. Does not cause the intense hunger seen with GHRP-6 or the cortisol/prolactin spikes seen with GHRP-2.
Ipamorelin is not fda-approved. research chemical. banned by wada.
Can You Stack Ipamorelin With Other Peptides?
Best paired with CJC-1295 no DAC for synergistic GH release — the GHRH + GHRP combination amplifies GH pulse amplitude beyond what either achieves alone. This is the most widely recommended beginner GH peptide stack.
What Is the Bottom Line on Ipamorelin?
Ipamorelin is a Growth Hormone Secretagogue (GHS) / Ghrelin mimetic researched for growth hormone release, improved sleep, fat loss, muscle recovery, bone density support. Standard protocols use 200-300 mcg 2-3 times daily for 8-12 weeks, often stacked with CJC-1295.
