Tesamorelin is a GHRH analogue that holds its own place within metabolic research. In this guide we explain, research-only, what Tesamorelin is, how it relates to other growth-hormone peptides and why in research it is associated with fat metabolism — without any weight-loss or health claims.
Tesamorelin is a stabilised GHRH analogue studied in metabolic and endocrine research, particularly around visceral adipose tissue. It is not a medicine in this context and is offered for research only, ≥99% pure with a COA per batch.
What is Tesamorelin?
Tesamorelin is a stabilised analogue of growth-hormone-releasing hormone (GHRH). Like other GHRH analogues it acts on the route that prompts the pituitary to release growth hormone, but its molecular structure gives Tesamorelin its own research profile. New to peptides? First read what peptides are.
Why Tesamorelin is associated with fat metabolism
In research Tesamorelin is mainly associated with visceral adipose tissue within the growth-hormone axis. That makes it an object of study at the intersection of endocrinology and metabolism. These descriptions come from a research context and are no proof of effect in humans; no weight-loss or health claims are attached to them.
Tesamorelin within the growth-hormone family
Tesamorelin belongs to the GHRH analogues, the same family as CJC-1295 — but each peptide has its own profile and research context. Where CJC-1295 is often studied with the GHRP Ipamorelin, Tesamorelin appears more often in metabolic research. Browse the full growth-hormone category to see the peptides side by side.
How is Tesamorelin reconstituted?
Tesamorelin is supplied as a lyophilised powder and reconstituted in the lab with bacteriostatic water. Use the reconstitution calculator to determine water, concentration and units, or read how to reconstitute peptides.
Purity and documentation
Reproducible metabolic research requires material with verified purity and full traceability. Every batch of Tesamorelin at Peptide Lab is tested by Janoshik Analytical at ≥99% purity by HPLC and mass spectrometry, with a public certificate per lot number.

Frequently asked questions about Tesamorelin
What is Tesamorelin?
Tesamorelin is a stabilised analogue of growth-hormone-releasing hormone (GHRH). It is studied in metabolic and endocrine research, particularly in relation to visceral adipose tissue. For research only.
What is the difference between Tesamorelin and CJC-1295?
Both are GHRH analogues, but with a different molecular structure and research profile. Tesamorelin appears mainly in metabolic research. This concerns preclinical and experimental context, not dosing or usage advice.
Why is Tesamorelin associated with fat metabolism?
In research Tesamorelin is associated with visceral (abdominal) adipose tissue within the growth-hormone axis. These are descriptions from research; no weight-loss or health claims are attached to them.
Is Tesamorelin pure at Peptide Lab?
Yes, Tesamorelin is lab-verified at ≥99% purity by HPLC and mass spectrometry, with a public Janoshik certificate per batch. For research purposes only.
