TESAMORELIN

Description

Tesamorelin is a synthetic peptide medication that stimulates your body to release more of its own growth hormone (GH).

It is a modified version of growth hormone-releasing hormone (GHRH) and is one of the few peptides in this category that is actually approved for medical use.

What it’s officially used for

Tesamorelin is approved under the brand:

* Egrifta

It is approved for reducing excess visceral abdominal fat in adults with HIV-associated lipodystrophy (abnormal fat distribution caused by HIV treatment).

⸻

How it works

Tesamorelin works by stimulating the pituitary gland to release natural growth hormone in pulses.

That growth hormone then increases levels of:

* IGF-1 (Insulin-like Growth Factor-1)

This can affect:

* Fat metabolism

* Body composition

* Muscle preservation

* Recovery processes

Unlike injecting HGH directly, tesamorelin encourages your body to produce its own GH instead.

⸻

Why people outside medicine talk about it

In bodybuilding and “biohacking” communities, tesamorelin gets attention for possible:

* Reduction of deep visceral belly fat

* Improved body composition

* GH/IGF-1 support

* Possible recovery and sleep benefits

However, the strongest evidence is specifically for visceral fat reduction, not general fat loss or muscle gain.

⸻

Important distinction

Tesamorelin mainly targets:

* Visceral fat = deep fat around organs

It is not primarily a subcutaneous fat burner (the softer fat under the skin).

Simple summary

Tesamorelin is a GHRH peptide that tells your pituitary gland to release more natural growth hormone, mainly used medically to reduce visceral abdominal fat in HIV-related lipodystrophy. It’s one of the few peptides with real FDA-approved human data behind it.
