Tesamorelin, development code TH9507 and clinically known as Egrifta, is a synthetic GHRH analogue of 44 amino acids. Rather than adding growth hormone, it gets the body to release more of its own. What the research aims at is strikingly specific: the deep belly fat around the organs. We supply it as a research-grade peptide at ≥99% HPLC purity, dispatched the same working day from the Netherlands.

Why this peptide turns on belly fat

One subject dominates tesamorelin research: stubborn belly fat. It is a GHRH analogue, a compound that prompts the body to make more of its own growth hormone instead of adding the hormone from outside. That natural route is thought to explain why the effect shows up mainly at visceral fat, the deep fat around the organs, and at body composition.

The brain's signal, mimicked

Tesamorelin passes itself off as GHRH, the hormone your brain uses to tell the pituitary that growth hormone is needed. Growth hormone and the related IGF-1 therefore rise in the natural, pulsing rhythm rather than in one artificial spike. That is thought to be where the emphasis on belly fat and recovery comes from. Because the peptide has been made more stable than ordinary GHRH, the action holds for longer.

Not a weight-loss drug, but aimed at visceral fat

The best-known research line turns on visceral fat, the deep belly fat around the organs that is hard to shift. Clinically the compound was developed for exactly that, under the name Egrifta. Worth keeping apart: this is not a general weight-loss drug like a GLP-1. It targets that specific fat depot via the growth hormone route and does nothing with your appetite.

What the clinical protocol used

In the clinical research on Egrifta, a daily subcutaneous injection was given at a fixed dose. Those figures come from the approved protocol and are documented in the literature; we do not carry them over as advice. BasePurity gives no dosing or administration advice for humans.

What was reported in the research?

The reactions that recurred most often in the clinical research were redness or itching at the injection site, fluid retention and at times pain in joints or muscles, which fits with raised growth hormone.

Placed next to ipamorelin

These two names often fall together in research, but they operate different switches. Tesamorelin is a GHRH analogue and prompts the pituitary from above. Ipamorelin is a GHRP, a ghrelin receptor agonist, and arrives at the same hormone through a different entrance. Because the routes complement each other, research sometimes combines them. If you want to compare them, ipamorelin sits separately in the range.

An exception: this one is a medicine

Unlike most research peptides, tesamorelin is approved somewhere: under the brand name Egrifta it is registered on prescription for a specific condition, HIV-associated lipodystrophy. As a research-grade peptide you may buy it and hold it for laboratory research. Note one point: as a growth-hormone-releasing factor it is on the WADA Prohibited List, in category S2, and so banned in sport. We supply for research only, not for human use.

Making it up and what we check

You receive a lyophilised vial that you make up yourself with bacteriostatic water. Every batch goes through purity (≥99%) and identity in the lab, so you know what is in the vial. Once made up, the vial goes into the fridge at 2–8 °C. The full specifications are in the table at the bottom of this page.
