Quickstart Highlights
Tesamorelin is a synthetic 44-amino-acid peptide analog of Growth Hormone-Releasing Hormone (GHRH). It stimulates endogenous growth hormone release and raises IGF-1 levels, leading to enhanced lipolysis and metabolic benefits. Tesamorelin is FDA-approved for reducing visceral adipose tissue in HIV-associated lipodystrophy and is studied for metabolic disorders and aging research.
- Reconstitute: Add 1.0 mL BAC water per labelled 10 mg vial; calculations assume a final volume of 1.0 mL and nominal concentration of 10 mg/mL.
- Standard daily dose: 2 mg (2000 mcg) once daily subcutaneously (FDA-approved protocol).
- Scale conversion: At 10 mg/mL, 1 U-100 unit = 0.01 mL = 100 mcg. Confirm actual device markings; this arithmetic does not establish measurement accuracy.
- Storage: Lyophilized & Reconstituted: refrigerate at 2–8 °C (35.6–46.4 °F)
Dosing & Reconstitution Guide
Standard FDA-Approved Protocol (1 mL = 10 mg/mL)
| Week | Daily Dose (mg / mcg) | Calculated volume | U-100 scale value (1 mL capacity) | V1 nominal setting (units) |
|---|---|---|---|---|
| Week 1 | 1 mg / 1000 mcg | 0.1 mL | 10 units | 10 units |
| Weeks 2–12+ | 2 mg / 2000 mcg | 0.2 mL | 20 units | 20 units |
Calculation basis: The table uses the labelled 10 mg amount and assumes a final solution volume of 1.0 mL (10 mg/mL). BAC volume does not change the amount of peptide. These are nominal calculations, not validation of preparation, compatibility or treatment.
Frequency: Inject once daily subcutaneously, preferably in the evening to coincide with nocturnal GH release. The 2 mg daily dose is the standard FDA-approved regimen for HIV lipodystrophy. A one-week titration at 1 mg may improve tolerability before advancing to the full 2 mg dose.
Reconstitution Steps
- Draw 1.0 mL bacteriostatic water with a sterile syringe.
- Inject slowly down the vial wall; avoid foaming.
- Gently swirl until dissolved (do not shake).
- Label and refrigerate at 2–8 °C (35.6–46.4 °F), protected from light.

Supplies Needed
Plan based on an 8–16 week daily protocol at the standard 2 mg dose (after Week 1 titration).
- Peptide Vials (Tesamorelin, 10 mg each):
- 8 weeks ≈ 11 vials (105 mg total)
- 12 weeks ≈ 17 vials (161 mg total)
- 16 weeks ≈ 22 vials (217 mg total)
- Insulin Syringes (U-100, 1 mL capacity):
- Per week: 7 syringes (1/day)
- 8 weeks: 56 syringes
- 12 weeks: 84 syringes
- 16 weeks: 112 syringes
- Bacteriostatic Water (30 mL bottles): Use 1.0 mL per vial. These volume-only totals use the listed vial counts; wastage and opened-bottle discard limits may require more.
- 8 weeks (11 vials): 11 mL → 1 × 30 mL bottle(s), minimum by volume
- 12 weeks (17 vials): 17 mL → 1 × 30 mL bottle(s), minimum by volume
- 16 weeks (22 vials): 22 mL → 1 × 30 mL bottle(s), minimum by volume
- Alcohol Swabs: One for the vial stopper + one for the injection site each day.
- Per week: 14 swabs (2/day)
- 8 weeks: 112 swabs → recommend 2 × 100-count boxes
- 12 weeks: 168 swabs → recommend 2 × 100-count boxes
- 16 weeks: 224 swabs → recommend 3 × 100-count boxes
Protocol Overview
Concise summary of the FDA-approved once-daily regimen.
- Goal: Reduce visceral adipose tissue and improve lipid profiles through sustained GH/IGF-1 elevation.
- Schedule: Daily subcutaneous injections for 12–26 weeks (extendable to 52 weeks with medical supervision).
- Dose: 2 mg (2000 mcg) daily after Week 1 titration.
- Reconstitution: 1.0 mL BAC per labelled 10 mg vial; nominal 10 mg/mL under the stated final-volume assumption.
- Storage: Lyophilized refrigerated; reconstituted refrigerated; avoid freeze-thaw.
Dosing Protocol
FDA-approved daily dosing approach with tolerability titration.
- Week 1: 1 mg (1000 mcg) once daily to assess tolerability.
- Weeks 2+: 2 mg (2000 mcg) once daily (standard FDA-approved dose).
- Frequency: Once per day (subcutaneous), preferably in the evening.
- Cycle Length: 12–26 weeks; clinical trials support up to 52 weeks with monitoring.
- Timing: Evening administration recommended; rotate injection sites.
Storage Instructions
Proper storage preserves peptide quality and activity.
- Lyophilized: Store at −20 °C (−4 °F) in dry, dark conditions; minimize moisture exposure.
- Reconstituted: Refrigerate at 2–8 °C (35.6–46.4 °F); do not freeze reconstituted solution as freezing can denature peptides.
- Allow vials to reach room temperature before opening to reduce condensation uptake.
- Use reconstituted vials within 28 days when stored with bacteriostatic water preservative.
Important Notes
Practical considerations for consistency and safety.
- Use new sterile insulin syringes for each injection; dispose in a sharps container.
- Rotate injection sites (abdomen at least 2 inches from navel, thighs, upper arms) to reduce local irritation.
- Inject slowly; wait a few seconds before withdrawing the needle.
- Monitor IGF-1 levels periodically due to potent GH stimulation; observe blood glucose in diabetic patients.
- Document daily dose and site rotation to maintain consistency.
How This Works
Tesamorelin mimics natural human GHRH by binding to pituitary GHRH receptors, triggering pulsatile growth hormone secretion and consequent IGF-1 elevation. This cascade promotes lipolysis (fat breakdown), protein synthesis, and favorable metabolic shifts. In HIV-associated lipodystrophy, daily tesamorelin significantly reduces visceral adipose tissue and improves lipid profiles over 6–12 months. Research also explores tesamorelin’s potential to reduce liver fat in NAFLD patients and enhance cognitive function in older adults by restoring age-related GH/IGF-1 declines.
Potential Benefits & Side Effects
Observations from clinical trials and FDA-approved use.
Potential Benefits:
- Significant reduction in visceral adipose tissue (measurable after 3–6 months).
- Improved lipid profiles and potential liver fat reduction in NAFLD.
- Enhanced cognitive function in older adults (research ongoing).
- Well-tolerated with maintained benefits during continuous use up to 52 weeks.
Common Side Effects:
- Injection-site reactions: Mild redness, itching, pain, or bruising at injection area.
- Musculoskeletal symptoms: Joint pain (arthralgia), muscle aches, peripheral edema (mild swelling).
- Carpal tunnel symptoms: Occasional tingling or numbness in extremities (dose-dependent, reversible).
- Metabolic monitoring: IGF-1 elevation requires monitoring; small increases in HbA1c observed in some patients.
Contraindications:
- Active malignancies (tesamorelin may accelerate growth of latent tumors).
- Pregnancy (may harm fetus).
- Known hypersensitivity to tesamorelin or mannitol.
Lifestyle Factors
Complementary strategies for optimal outcomes.
- Combine with a balanced, protein-forward diet to support GH/IGF-1 anabolic effects.
- Integrate resistance training and aerobic activity to maximize fat loss and metabolic benefits.
- Prioritize 7–9 hours of quality sleep to optimize natural GH pulsatility.
- Manage stress through mindfulness or relaxation techniques to support adherence and recovery.
Injection Technique
Subcutaneous injection best practices from clinical guidelines.
- Clean the vial stopper and skin with alcohol swabs; allow to air-dry completely.
- Pinch a skinfold at the injection site (abdomen preferred, at least 2 inches from navel).
- Insert the needle at 90° (if adequate subcutaneous fat) or 45° (if lean).
- Release the pinch, then inject slowly; wait 2–3 seconds before withdrawing.
- Rotate injection sites systematically (left/right abdomen, thighs, upper arms) to prevent lipohypertrophy.
- Dispose of used syringes immediately in a puncture-proof sharps container.
