What is the difference between GHRH (1–44) and Tesamorelin?

GHRH (1–44) (Growth Hormone Releasing Hormone, full sequence) is graded A and is FDA-approved (Geref) historically as diagnostic GH stimulant; current US availability limited. 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 — GHRH (1–44) or Tesamorelin?

On our internal evidence scale, GHRH (1–44) is A and Tesamorelin is A. A+ indicates large RCTs plus FDA approval; C indicates primarily preclinical or anecdotal evidence.

What is the typical dose of GHRH (1–44) vs Tesamorelin?

GHRH (1–44): 1 mcg/kg IV (diagnostic test). Tesamorelin: 2 mg daily (subcutaneous). Always work with a licensed clinician — peptide dosing should be individualized.

GHRH (1–44) vs Tesamorelin

Both GHRH (1–44) and Tesamorelin are used for growth-hormone. Here's how their evidence, dosing, and regulatory status actually compare.

GHRH (1–44)

Evidence A

Growth Hormone Releasing Hormone, full sequence

The full 44-amino-acid GHRH sequence. The natural pituitary stimulus for GH release. Largely supplanted in clinical use by sermorelin/tesamorelin but remains a research and diagnostic tool.

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.
