The short answer
What is tesamorelin, and what does it do?
Tesamorelin is a growth-hormone-releasing hormone (GHRH) analog: it prompts the pituitary to release growth hormone in a natural, pulsatile pattern rather than delivering growth hormone directly. Its best-documented effect is a reduction in visceral adipose tissue, the deep abdominal fat that wraps the organs. In a controlled human trial the studied regimen was 2 mg injected subcutaneously once daily, and it reported a visceral-fat reduction of about 15 percent measured by imaging (Falutz et al., NEJM 2007, PMID 18057338). That is a group result in a specific patient population for a specific indication, not a schedule or a dose for any individual. What ships here is research-grade tesamorelin with a batch COA, distinct from the FDA-approved branded pharmaceutical, and any personal dose is a decision for a qualified clinician.
The Science
The Fat You Cannot Pinch, and What Was Measured
Tesamorelin is a GHRH analog, so the described route is stimulation of endogenous growth-hormone release rather than administration of growth hormone. A controlled human trial reported a reduction in visceral adipose tissue of about 15 percent, the deep abdominal fat linked to metabolic disease (Falutz et al., NEJM 2007, PMID 18057338).
GHRH Analog
Prompts the pituitary to release growth hormone in a natural, pulsatile pattern.
Visceral Fat
Studied in clinical trials specifically for reducing deep abdominal visceral fat.
Clinical Grounding
Backed by registered clinical trials, unlike many purely research peptides.
Dosage as studied
What tesamorelin dosage did the research use?
The figures below describe what a published trial administered, not a dose for any person. The pivotal tesamorelin study fixed a single daily amount rather than titrating across arms, so there is no multi-dose chart the way weekly GLP-1 trials have one (Falutz et al., NEJM 2007, PMID 18057338).
| Studied regimen | Route and frequency | Reported endpoint | Source |
|---|---|---|---|
| 2 mg | Subcutaneous, once daily | Visceral adipose tissue down about 15 percent by imaging | Falutz et al., NEJM 2007 |
Because that trial ran a single fixed regimen, questions like a per-week total or a cycle length are extrapolations beyond what it measured. Published visceral-fat protocols ran over extended periods with periodic imaging to reassess, and any dosing schedule, route, or injection site is a clinical decision for a licensed physician rather than something to copy from a protocol. The concentration math for a lyophilized 20mg vial, in units rather than mL, is on the reconstitution calculator.
Comparisons
Tesamorelin vs sermorelin vs ipamorelin: how do they differ?
These three get grouped together because all raise growth hormone, but they are not the same class and no published head-to-head trial compares them. Tesamorelin and sermorelin are GHRH analogs, which act on the GHRH receptor; ipamorelin is a ghrelin-mimetic secretagogue that acts on a different receptor. The table sorts them by what the published record actually measured.
| Peptide | Class | What the record emphasizes | Source / note |
|---|---|---|---|
| Tesamorelin | GHRH analog | Controlled trial reporting about 15 percent visceral-fat reduction by imaging | Falutz et al., NEJM 2007 |
| Sermorelin | GHRH analog (GHRH 1-29) | Older, shorter-acting GHRH analog long used in growth-hormone-axis contexts; no visceral-fat imaging endpoint of that kind | See the sermorelin dosage page |
| Ipamorelin | Ghrelin-mimetic secretagogue | Different receptor from the GHRH analogs; the ghrelin-mimetic class has its own body-composition trial | Nass et al., 2008 (class) |
A separate long-acting GHRH analog, CJC-1295, was shown to prolong growth-hormone and IGF-I secretion in healthy adults, which is the appeal of a longer-acting GHRH analog (Teichman et al., 2006). A tesamorelin-and-ipamorelin blend pairs a GHRH analog with a ghrelin-mimetic secretagogue, two different pathways, but no published trial measured that combination, so any pairing claim is extrapolation rather than a measured result. Peptara Labs does not design combinations for anyone. For the sermorelin side, see the sermorelin dosage page.
Applications
Common Use Cases
Visceral Belly Fat
Visceral adipose tissue measured by imaging is the endpoint the human trial used.
Body Recomposition
Body composition is a studied endpoint for the growth-hormone axis generally.
Sleep and Recovery
Sleep depth is a studied endpoint for growth-hormone secretagogues as a class.
GLP-1 stacking research
No published trial measured tesamorelin in combination with a GLP-1 or another secretagogue. GLP-1 trials measured total body weight; this one measured visceral fat by imaging. Different endpoints, separate trials.
Ordering
Where to Buy Tesamorelin
Tesamorelin is supplied here as a research compound, not as the approved branded pharmaceutical, so what separates one 20mg vial from another is documentation. Three things are worth checking before you order anywhere, including here.
Know which tesamorelin it is
Egrifta is the FDA-approved branded pharmaceutical. What is supplied here is research-grade tesamorelin, which is not an FDA-approved product. A seller who blurs those two has told you how they operate.
A batch certificate, not a generic one
Ask for the third-party Certificate of Analysis for the exact batch being sent to you. Every Peptara Labs vial has one, and the released figures sit on our COA page.
A named business and handling you can check
Peptara Labs is a registered business reachable on WhatsApp before and after the order. Vials travel lyophilized, stable at room temperature for weeks, and go in the refrigerator once reconstituted.

What published reports describe, week by week
The trial
Tesamorelin was studied in humans and reported a reduction in visceral adipose tissue of about 15 percent (Falutz et al., NEJM 2007, PMID 18057338).
Mechanism
It is a GHRH analog, so the described route is stimulation of endogenous growth-hormone release rather than administration of growth hormone.
Measured endpoint
The endpoint in that trial was visceral adipose tissue measured by imaging, in a specific patient population, for a specific indication.
Approval status
The brand drug has clinical history for that specific indication. Research-grade tesamorelin, including ours, is not an approved medicine.
Weeks 12+
Published protocols for visceral fat run over extended periods, with periodic reassessment.
