Sermorelin vs Ipamorelin
A detailed side-by-side comparison of Sermorelin and Ipamorelin covering dosing, storage, research findings, and practical usage.
Overview
Sermorelin: A GHRH analog that naturally stimulates the pituitary to release growth hormone.
Ipamorelin: A selective GH secretagogue with minimal effect on cortisol or prolactin.

Ipamorelin Research
Ipamorelin is a synthetic pentapeptide that acts as a selective growth hormone secretagogue. Unlike other GHRPs, ipamorelin specifically stimulates growth hormone release without significantly affecting cortisol, prolactin, or aldosterone levels, making it one of the cleanest GH-releasing peptides available. Research shows it provides a controlled, dose-dependent GH pulse similar to natural secretion patterns. Studies demonstrate benefits for body composition, sleep quality, and recovery. Ipamorelin is often combined with CJC-1295 (no DAC) for synergistic effects, as they work through complementary pathways (GHRP + GHRH).
