About Tesamorelin

Tesamorelin is a synthetic GHRH analogue, modified for stability. Growth-hormone and metabolic research know it well. Vials come in 5, 10 and 20 mg.

Tesamorelin comes in sealed kits of 10 or 30 freeze-dried vials. Certificates from an independent third-party laboratory are published per batch on /certificates as they become available. For laboratory and in-vitro research only.

Mechanism of action

Tesamorelin copies human growth-hormone-releasing hormone, GHRH(1–44), and adds a trans-3-hexenoyl group at the N-terminus. That group shields it from dipeptidyl peptidase-4, the enzyme that cuts native GHRH within minutes.

It binds the GHRH receptor in the pituitary. It prompts release of the body’s own growth hormone and does not supply growth hormone itself. Because of that difference, papers class it apart from recombinant GH.

A short summary of published work, given as research context. It makes no therapeutic claim.

What published studies show

A 2011 drug profile in Nature Reviews Drug Discovery describes the compound. A 2024 study in AIDS reports efficacy and safety data in people with HIV taking integrase inhibitors.

After the incretins, tesamorelin has the most clinical data of anything in this range. Some jurisdictions have approved it for a specific indication. NordPeps sells it for laboratory research only.

Storage & handling

Unopened vials. Store at 2–8 °C. For long periods, −20 °C or colder. Room temperature is fine in transit, but it is not a way to store a peptide.

After reconstitution. Refrigerate at 2–8 °C. Do not freeze: ice crystals break the peptide down for good. In bacteriostatic water (0.9% benzyl alcohol), labs usually work through a vial within about 30 days. With plain sterile water, the window is 24–48 hours.

Keep vials closed and out of the light. If you hold frozen stock, thaw it as few times as you can; each cycle loses some activity.

Tesamorelin: common questions

How much does Tesamorelin cost?

A 10-vial kit costs €339 (5 mg), €449 (10 mg) or €569 (20 mg). A 30-vial kit costs three times as much (€1,017, €1,347 or €1,707). Delivery is free on every kit, to all 27 EU countries.

Is there a certificate for this compound?

Certificates from an independent third-party laboratory are published per batch on /certificates as they become available.

What does GHRH analogue mean?

A synthetic peptide that imitates growth-hormone-releasing hormone. Tesamorelin is among the best described. Laboratory research use only.

Why kits of 10 vials?

We sell this compound only in sealed kits of 10 identical vials, or 30. A 10-vial kit is the smallest order.

How do I store Tesamorelin?

Unopened: 2–8 °C; for long stretches, −20 °C. Reconstituted: in the fridge, never frozen. Details are under storage and handling.

How is the concentration set?

By the volume of bacteriostatic water you add, not by the vial size alone. Enter the vial size and the diluent volume in the reconstitution calculator and it gives you the concentration.

How is it different from the CJC-1295 / Ipamorelin kit?

Tesamorelin is one GHRH analogue on its own. The CJC-1295 / Ipamorelin kit pairs a GHRH analogue with a separate ghrelin-receptor secretagogue, so two receptors are involved.

Sealed kits, dispatched inside the EU.

Kits leave us 24–48 hours after payment, in a plain box with tracking. Delivery stays within the EU. Laboratory research use only.
