What is Tesamorelin / Ipamorelin?

Tesamorelin / Ipamorelin is a two-peptide research blend pairing a stabilised GHRH(1-44) analogue with a selective pentapeptide secretagogue, supplied as a lyophilised powder. It is supplied strictly for laboratory research use only.

What research area is Tesamorelin / Ipamorelin associated with?

Published preclinical laboratory work in this class concerns GHRH and GHS-R1a receptor signalling chemistry. We supply the material only; we make no representation as to any outcome, effect, or suitability for any purpose.

Is Tesamorelin / Ipamorelin approved for human use?

No. Tesamorelin / Ipamorelin is not a drug, supplement, food, cosmetic, or medical device, and has no approved human or veterinary indication. It is sold strictly for in-vitro laboratory research use by qualified professionals.

What purity is Tesamorelin / Ipamorelin supplied at, and how is it verified?

Each lot is assayed by HPLC and ships with its own lot-specific Certificate of Analysis, published in our COA registry. Purity figures are stated per lot - we do not publish a brand-wide specification in place of the actual certificate.

Proof, not promises. Every batch, tested by an outside lab.

Every batch of Tesamorelin / Ipamorelin is tested by an outside lab before it goes on sale — not by us. The one shipping now is lot TSIP14-052026-1: 99.71% pure by HPLC, tested by Freedom Diagnostics on 02 Jun 2026. The signed report is right here. Purity is the number the lab measured, never “at least 99” — and a batch that misses its spec never ships.

How Tesamorelin / Ipamorelin works

A two-peptide pairing studied for a bigger, cleaner GH pulse through two receptors.

GHRH receptorTesamorelin

Studied for prompting natural, pulse-like growth-hormone release via the GHRH receptor.

Ghrelin receptorIpamorelin

Investigated for a clean GHS-R signal that adds GH release without cortisol or prolactin spikes.

IGF-1 amplificationdual pathway

Researched for amplifying the IGF-1 response beyond what either peptide reaches alone.

What the studies found

Published findings on this compound, each linked to its source. Animal and lab results are context, not claims about this product.

Visceral fatClinical

−15.2%

In a 412-person randomised trial of tesamorelin in people with HIV-associated fat accumulation, visceral fat fell 15.2% over 26 weeks while it rose 5.0% on placebo.

Clean GH releasePreclinical

In pigs, ipamorelin released growth hormone without raising ACTH or cortisol above the level seen with the body's own GHRH signal — even at more than 200 times the amount needed.

IGF-1 responsePreclinical

Growth hormone secretagogues act synergistically with GHRH but through a different receptor — the reason a GHRH analogue and a secretagogue are studied together.
