Performance comparison

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.

Growth Hormone Axis
Ipamorelin

Selective GH secretagogue with a clean research profile.

Mechanism

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.

Research areas
  • Endogenous GH release without cortisol elevation
  • Sleep quality and recovery markers
  • Lean tissue retention in catabolic states
Considerations
  • Generally well tolerated in research; long-term human safety data are limited.
  • Not FDA-approved.
  • Use in sport is prohibited (WADA).

Growth Hormone Axis
Tesamorelin

GHRH analog FDA-approved for HIV-associated visceral fat.

Mechanism

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.

Research areas
  • Visceral adipose tissue reduction (approved)
  • Cognitive function in older adults (research)
  • NAFLD / hepatic fat (research)
Considerations
  • FDA-approved only for HIV-associated lipodystrophy.
  • May affect glucose tolerance; monitor in at-risk patients.
  • Requires physician oversight.
