Sequence, molecular data, research status and testing standards for Tesamorelin, written for Canadian researchers.
Tesamorelin is a synthetic analogue of human growth hormone-releasing hormone (GHRH). It contains all 44 amino acids of natural GHRH plus a small fatty-acid group that protects it from rapid breakdown. It is marketed as the prescription drug Egrifta in the United States.
Tesamorelin was approved in the United States in 2010 as a prescription treatment for excess abdominal fat in people with HIV-associated lipodystrophy. It acts on the pituitary to stimulate the body's own growth hormone release, and it has also been studied in clinical research on liver fat and the growth hormone axis.
What it isA longer-lasting lab copy of the body's own signal to release growth hormone.
The plain-English storyA long-lasting lab copy of the body's own 'release growth hormone' cue. In the United States it is an approved prescription medicine for one specific condition, which is very different from the general 'fat-loss' stories online. It is banned in sport.
How it works, in simple termsIt tells the body's master gland to release growth hormone.
What the science really showsUsed in the United States as a prescription medicine for a specific condition.
What you may hear onlineVideos often describe it as a fat-loss peptide.
The straight storyIn the United States it is approved for one specific medical condition. That is not the same as general fat loss.
Where it stands in CanadaA prescription medicine in the US. Banned in sport.

| Structure | Status | |
|---|---|---|
| Sermorelin | GHRH amino acids 1–29 | Formerly marketed; now mainly research |
| CJC-1295 (no DAC) | Stabilized GHRH 1–29 (Mod GRF 1-29) | Research peptide |
| Tesamorelin | Full GHRH 1–44 + fatty-acid group | Prescription drug (Egrifta) |
All three signal the pituitary gland to release growth hormone. See the CJC-1295 + Ipamorelin profile or compare peptides side by side.
Tesamorelin is a prescription drug. Prescription drugs may only be sold in Canada through licensed pharmacies with a valid prescription, and only where they are authorized. Selling tesamorelin for human use outside that system is illegal. Peptide Authority does not sell tesamorelin. Read how peptides are regulated in Canada.

Peptide Authority does not sell tesamorelin. It is a prescription drug, so it should only come from a licensed pharmacy with a prescription. Products sold online as "research" tesamorelin are unregulated and their contents cannot be verified. Speak with a licensed healthcare professional about treatment options.
All three are GHRH analogues. Sermorelin is the first 29 amino acids of GHRH; CJC-1295 (no DAC) is a stabilized version of those 29 amino acids; tesamorelin is the full 44-amino-acid sequence with a protective fatty-acid group. Only tesamorelin is a currently marketed prescription drug.
Yes. Tesamorelin is on the World Anti-Doping Agency (WADA) Prohibited List: Prohibited: S2 (GHRH and its analogues).
