Ipamorelin vs Tesamorelin
An educational, source-based comparison of Ipamorelin and Tesamorelin — how each peptide works, what it's researched for, and what to know before going deeper.
A selective ghrelin/GHS-R1a receptor agonist that stimulates GH release with minimal effect on cortisol, prolactin, or appetite — distinguishing it from older secretagogues like GHRP-6.
- Endogenous GH release without cortisol elevation
- Sleep quality and recovery markers
- Lean tissue retention in catabolic states
- • Generally well tolerated in research; long-term human safety data are limited.
- • Not FDA-approved.
- • Use in sport is prohibited (WADA).
A stabilized analog of growth hormone-releasing hormone (GHRH) that stimulates pulsatile endogenous GH and IGF-1 release. FDA-approved (Egrifta) for the reduction of excess abdominal visceral fat in HIV-infected patients with lipodystrophy.
- Visceral adipose tissue reduction (approved)
- Cognitive function in older adults (research)
- NAFLD / hepatic fat (research)
- • FDA-approved only for HIV-associated lipodystrophy.
- • May affect glucose tolerance; monitor in at-risk patients.
- • Requires physician oversight.
Ipamorelin vs Tesamorelin — Key differences
- Class: Ipamorelin is classified as Growth Hormone Axis, while Tesamorelin is Growth Hormone Axis.
- Primary research focus: Ipamorelin — endogenous gh release without cortisol elevation; Tesamorelin — visceral adipose tissue reduction (approved).
