Tesamorelin protocol
Tesamorelin (stabilised GHRH analog). Dosing on this page comes from a published human trial or an approved product label, cited below.
How Tesamorelin works
A GHRH analog with a trans-3-hexenoyl group added to the N-terminus, which protects it from degradation by dipeptidyl peptidase-4 and extends its activity relative to unmodified GHRH.
Tesamorelin dosing schedule
From the approved label. Tesamorelin is the strongest-evidenced compound in this category — it holds a current FDA approval, marketed as Egrifta, for reduction of excess visceral abdominal fat in HIV-associated lipodystrophy. That specific indication is what the trials studied.
| Phase | Amount | Frequency | Notes |
|---|---|---|---|
| Approved use | 2 mg | Once daily, subcutaneous | The single approved amount for the labelled indication. |
Study length: Phase 3 trials ran 26 weeks with a 26-week extension. The label notes benefit is not maintained after discontinuation.
Reconstitution and measurement
This part is arithmetic and does not depend on the evidence level. Concentration is vial size divided by the bacteriostatic water you add. Draw volume is your target amount divided by that concentration. Units are draw volume times 100, because a U-100 syringe reads 100 units per millilitre. Common vials for Tesamorelin: 10 mg.
Storage and stability
Reported effects
- Trial reporting notes injection-site reactions, arthralgia and peripheral oedema.
- Because it raises IGF-1, the label carries monitoring guidance and contraindications including active malignancy.
- Visceral fat returned toward baseline after stopping in the extension study.
Sourcing Tesamorelin
Whatever you are working with, the documentation matters more than the price. Ask for a batch certificate of analysis whose lot number matches the vial you actually receive — a COA for a different batch tells you nothing about yours.
