What Is Tesamorelin?
Tesamorelin (brand name Egrifta) is a synthetic analog of GHRH — the full 44 amino acids of human GHRH(1–44) with a trans-3-hexenoic acid N-terminal modification for stability. It received FDA approval in 2010 for reducing excess abdominal fat (lipodystrophy) in HIV-infected patients. Unlike exogenous HGH, it stimulates pulsatile GH release while preserving the somatostatin feedback loop, reducing supraphysiological GH/IGF-1 risk. Trials showed 15–18% reduction in visceral adipose tissue over 26 weeks.
Dosing derives from clinical studies, published research and community protocols.
Key Characteristics
- GHRH analog (44 amino acids) — the only FDA-approved GHRH analog.
- FDA-approved (2010) — for HIV-associated lipodystrophy (Egrifta / Egrifta SV).
- Pulsatile GH release — preserves the somatostatin feedback loop.
- Visceral-fat specificity — 15–18% VAT reduction over 26 weeks; minimal effect on subcutaneous fat.
- Cognitive potential — STAY study (2019) showed preserved cognition in HIV-positive older adults.
How Dosage Is Determined
Uniquely well-established — full FDA approval process. The 2 mg daily dose was selected in Phase II and confirmed in Phase III RCTs (>800 patients; Falutz et al. 2007, 2010). VAT reduction of 15–18% vs placebo at 26 weeks. STAY study: 12-month cognitive RCT. Strength of evidence: strong.
Standard Dosage
Fixed 2 mg daily dose regardless of body weight, sex or severity.
| Protocol | Dose | Frequency | Notes |
|---|---|---|---|
| FDA-Approved (Egrifta) | 2 mg SubQ | Once daily | Phase III trial dose; 26-week endpoint |
| Standard Off-Label | 2 mg SubQ | Once daily | Body composition / anti-aging; evening injection |
| Conservative | 1 mg SubQ | Once daily | Less clinical data at this dose |
| 5-on / 2-off (Community) | 2 mg SubQ | 5 days/week | Extends vial use; not studied in trials |
Reconstitution & Dosing (with the supplied 3 mL)
Every Clean Peptides vial ships with 3 mL of bacteriostatic water (0.9% benzyl alcohol). All figures below assume you reconstitute with the full 3 mL. On a standard U-100 insulin syringe, 100 units = 1 mL.
Quick formula: concentration = vial strength ÷ 3 mL, and units to draw = dose (mg) × 300 ÷ vial strength (mg).
How to reconstitute
- Wash your hands and lay out the vial, the 3 mL bacteriostatic water, an insulin syringe and alcohol swabs on a clean surface.
- Flip off the caps and swab both rubber stoppers with alcohol; let them air-dry 10–15 seconds.
- Draw the full 3 mL of bacteriostatic water (in three 1 mL passes with an insulin syringe, or in one pass with a 3 mL syringe).
- Add the water slowly, angling the needle so it runs down the inside glass wall — never squirt it directly onto the powder cake.
- Dissolve gently — let the vial sit 1–2 minutes, then swirl or roll it between your palms until the solution is clear. Never shake.
- Label and refrigerate at 2–8 °C. Resulting concentration: 10 mg → 3.33 mg/mL.
Storage: unreconstituted powder refrigerated (2–8 °C); reconstituted solution refrigerated and used within 28–30 days; do not freeze; protect from light and heat.

| Vial (Clean Peptides) | Concentration | 1 mg | 2 mg |
|---|---|---|---|
| 10 mg | 3.33 mg/mL | 30 u | 60 u |
Dosage by Goal
- Visceral fat reduction (FDA indication): 2 mg SubQ daily × 26 weeks minimum. CT/DEXA at baseline and 26 wk; IGF-1 at baseline, 8 wk, 26 wk. Evening/bedtime, fasted 1–2 h.
- Body composition & anti-aging (off-label): 2 mg SubQ daily, evening/bedtime, fasted; 12–26 weeks then break.
- Cognitive support: 2 mg SubQ daily × 12 months (STAY study); data limited to HIV-positive population.
Injection Guide
- Wash hands; prepare a clean workspace.
- Swab the vial stopper; air-dry.
- Draw the dose (typically the full vial for 2 mg); tap out bubbles.
- Choose the abdomen (FDA-approved site), 2–3 in from navel; avoid scar tissue.
- Clean the site; air-dry.
- Inject into a pinched fold at 45°.
- Dispose in a sharps container.
Optimal timing: evening/bedtime (synergizes with nocturnal GH surge), fasted 1–2 h. Consistent daily dosing; rotate within the abdomen.
Cycle Duration & Timing
| Protocol | Duration | Notes |
|---|---|---|
| Standard (FDA trial) | 26 weeks daily | Phase III primary endpoint |
| Extended | 52 weeks daily | Maintained benefit; longest studied |
| Cyclical | 26 wk on, 8–12 wk off, repeat | Pituitary recovery, cost management |
| 5-on / 2-off weekly | Ongoing, 5 days/week | Reduces cost ~30%; not studied |
Visceral fat reaccumulates after discontinuation; IGF-1 normalizes within weeks. No PCT required (pituitary not suppressed).
Stacking Protocols
Tesamorelin + Ipamorelin — GHRH + GHRP synergy (gold standard): Tesamorelin 2 mg SubQ evening + Ipamorelin 200–300 mcg SubQ bedtime, fasted. Separate receptor pathways → synergistic GH response.
Full Ipamorelin protocols: see our Ipamorelin Dosage Guide.
Other stacks: + AOD-9604 (direct lipolysis, morning fasted); + BPC-157 (GH optimization + tissue repair).
Safety, Side Effects & Contraindications
Cancer screening required — GH/IGF-1 promote cell growth; active malignancy is an FDA-labeled contraindication. Complete age-appropriate screening before starting.
Common (Phase III): injection-site reactions (~13%), arthralgia (~13%), peripheral edema, myalgia. Less common: hyperglycemia/insulin resistance, carpal tunnel syndrome, paresthesia, nausea.
Contraindications: active malignancy; disrupted hypothalamic-pituitary axis; pregnancy (Category X); hypersensitivity (incl. mannitol); uncontrolled diabetes.
Monitor: IGF-1 (baseline, 8 wk, 26 wk), fasting glucose & HbA1c, cancer screening, thyroid panel, lipids. Do not combine with exogenous HGH. Prescription medication; WADA-prohibited.
Common Mistakes
- Injecting after a meal instead of fasted.
- Expecting HGH-level results from a GHRH analog.
- Stopping before 26 weeks.
- Skipping IGF-1 monitoring.
- Combining with exogenous HGH.
- Starting without cancer screening.
- Inconsistent daily dosing.
- Using Egrifta (sterile water) beyond 24 hours.
Key Takeaways
- The only FDA-approved GHRH analog; strongest clinical evidence of any GH peptide.
- Fixed 2 mg SubQ once daily (no weight-based adjustment).
- Pulsatile GH release preserving feedback; 15–18% visceral fat reduction over 26 weeks.
- Inject at bedtime, fasted. Top stack: Tesamorelin + Ipamorelin.
- Cancer screening required; monitor IGF-1; do not combine with HGH.
