Ipamorelin
Ipamorelin is a selective agonist at the GH secretagogue receptor (GHSR-1a). Compared to GHRP-2 and GHRP-6 its selectivity for the growth-hormone axis is higher; ACTH, cortisol and prolactin are not significantly stimulated in clinical studies. This selectivity was the main reason for its development over older GHRPs.
Tesamorelin
Tesamorelin is an N-terminally modified 44-amino-acid version of human GHRH(1-44). A 3-hexenoyl modification protects against rapid dipeptidyl-peptidase-IV cleavage. Binding to the pituitary GHRH receptor stimulates endogenous pulsatile growth-hormone secretion and consequently hepatic IGF-1 production.

Frequently asked questions
- What is the difference between Ipamorelin and Tesamorelin?
- Ipamorelin is classified as "Рост", while Tesamorelin is classified as "Рост". Ipamorelin: Synthetic pentapeptide and selective growth-hormone secretagogue. Developed at Novo Nordisk in the 1990s as a pentapeptide GHRP successor; clinical development was discontinued after phase 2 (post-operative ileus). Tesamorelin: Stabilised GHRH analog (growth-hormone-releasing hormone). FDA-approved in 2010 as Egrifta for reduction of abdominal lipohypertrophy in HIV-associated lipodystrophy. Not approved for the general population. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Ipamorelin or Tesamorelin?
- The highest available evidence level is "РКИ на людях" for Ipamorelin and "РКИ на людях" for Tesamorelin. A higher evidence level means more robust data, but says nothing about suitability for an individual. The full body of evidence is on each peptide's own page.
- What is the legal status of Ipamorelin and Tesamorelin in Germany and the United States?
- Германия: Ipamorelin — Не одобрено, Tesamorelin — Не одобрено. США: Ipamorelin — Не одобрено, Tesamorelin — Рецептурный. These are factual summaries with source and review date on the individual pages.
