What is the difference between Sermorelin and Tesamorelin?

Sermorelin (Sermorelin Acetate (GHRH 1-29)) is graded B+ and is FDA-approved (1990) for pediatric growth hormone deficiency; off-label adult use via compounding pharmacies. Tesamorelin (Tesamorelin (Egrifta)) is graded A and is FDA-approved for HIV-associated lipodystrophy. They are commonly compared because they share the categories: growth-hormone.

Which has stronger clinical evidence — Sermorelin or Tesamorelin?

On our internal evidence scale, Sermorelin is B+ and Tesamorelin is A. A+ indicates large RCTs plus FDA approval; C indicates primarily preclinical or anecdotal evidence.

What is the typical dose of Sermorelin vs Tesamorelin?

Sermorelin: 200–500 mcg before bed (subcutaneous). Tesamorelin: 2 mg daily (subcutaneous). Always work with a licensed clinician — peptide dosing should be individualized.

Sermorelin vs Tesamorelin

Both Sermorelin and Tesamorelin are used for growth-hormone. Here's how their evidence, dosing, and regulatory status actually compare.

Sermorelin

Evidence B+

Sermorelin Acetate (GHRH 1-29)

The original synthetic GHRH(1–29) and the most accessible GH-stimulating peptide for age-related hormone decline. Stimulates the body's own pulsatile GH release rather than replacing it.

Tesamorelin

Evidence A

Tesamorelin (Egrifta)

An FDA-approved GHRH analog that stimulates natural growth hormone production. Clinically proven to reduce visceral adipose tissue and increasingly used off-label for body recomposition.
