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

Tesamorelin

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.

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.
