Tesamorelin is a 44-amino-acid synthetic analog of growth hormone-releasing hormone (GHRH), with an added trans-3-hexenoic acid group that increases its stability compared to native GHRH. It acts on the GHRH receptor in the anterior pituitary to stimulate endogenous GH secretion, and has been used in both clinical and pre-clinical research contexts to study GHRH receptor pharmacology.
Research has investigated Tesamorelin's pharmacokinetics in relation to GH pulse stimulation, its receptor binding characteristics, and how GHRH agonism influences downstream IGF-1 signaling in pre-clinical endocrine models. Studies have also examined how its extended stability profile compared to native GHRH affects duration of receptor activation and GH secretion dynamics, making it a useful research tool for characterizing GHRH receptor responses.
Tesamorelin has also been investigated in models examining visceral adipose tissue biology, where GH signaling plays a regulatory role in lipid metabolism pathways — an area that has made it a compound of interest in both endocrinology and metabolic research settings.
myPEPT supplies Tesamorelin at ≥99% verified purity with a Certificate of Analysis from independent third-party lab testing. Lyophilized and shipped across the EU in research-grade packaging.
What researchers should know: Tesamorelin is a research peptide supplied for laboratory use only. While it has a clinical analog, this product is not approved for human use outside of licensed clinical settings. Handle in accordance with your institution's endocrine peptide research protocols and all applicable local regulations.

Frequently asked
8 questionsHow fast is delivery and which carriers do you use?
Orders placed before 16:00 CET ship the same business day from the Netherlands via DPD or PostNL. EU-wide delivery typically takes 2–5 working days, fully tracked. Every parcel ships in plain, unbranded packaging with no peptide-related markings visible.
Which payment methods do you accept?
We accept iDEAL (Netherlands), Bancontact (Belgium), PayPal, Klarna pay-later, SEPA instant bank transfer, and Visa/Mastercard credit and debit cards. All payments are processed through PCI-DSS-compliant European processors. Bank transfer and card orders ship within 24 hours of payment confirmation.
How do you verify peptide purity?
Every batch is HPLC-tested to 99% purity or higher by an independent third-party laboratory, with identity confirmed by mass spectrometry. The batch-specific Certificate of Analysis is published on every product page and delivered with the order.
Are research peptides legal to buy in the Netherlands and EU?
Yes — when sold and purchased strictly for in-vitro laboratory research. Research peptides on my\PEPT.eu are not approved, marketed or intended for human or veterinary use, medical diagnosis or therapeutic application. By placing an order you confirm research-only intent and accept responsibility for compliance with local regulations.
How should research peptides be stored?
Lyophilized (freeze-dried) peptides keep up to 24 months at −20 °C in a sealed vial. Once reconstituted in bacteriostatic water, store at 2–8 °C and use within 28 days. Avoid repeated freeze-thaw cycles and direct sunlight.
What is Tesamorelin as a research peptide?
Tesamorelin is a synthetic analogue of growth hormone-releasing hormone (GHRH) consisting of the full 44-amino-acid GHRH sequence with a trans-3-hexenoic acid modification at the N-terminus, giving a molecular weight of approximately 5,135 Da. It is studied in laboratory research for its binding affinity at the GHRH receptor. my\PEPT.eu supplies Tesamorelin for in-vitro research use only — not for human or veterinary consumption.
How should Tesamorelin be stored?
Lyophilized Tesamorelin is stable for up to 24 months at −20 °C in a sealed vial. Once reconstituted in bacteriostatic water for laboratory assay purposes, store at 2–8 °C and use within 28 days. Avoid repeated freeze-thaw cycles and direct sunlight. Research-use only — not for human use.
What does the Certificate of Analysis show for Tesamorelin?
The batch-specific CoA for Tesamorelin confirms HPLC purity at 99 % or higher, sequence identity by mass spectrometry, batch number, net peptide content, and water content by Karl Fischer titration. Download the CoA from the Tesamorelin product page. Not for human or veterinary consumption.
