Performance comparison

Hexarelin vs Tesamorelin

An educational, source-based comparison of Hexarelin and Tesamorelin — how each peptide works, what it's researched for, and what to know before going deeper.

Growth Hormone Axis · Cardiac
Hexarelin

Potent ghrelin-mimetic with cardiac research interest.

Mechanism

A synthetic hexapeptide and potent GHS-R agonist. Stimulates GH release more strongly than GHRP-6 and shows cardioprotective signaling in preclinical ischemia-reperfusion models, partly independent of GH.

Research areas
  • GH release
  • Cardiac ischemia-reperfusion (preclinical)
  • Left ventricular function in animal models
Considerations
  • Not FDA-approved.
  • Tachyphylaxis with prolonged use.
  • Prohibited by 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.
