Tesamorelin (10 mg Vial)

  • Table of Contents

Tesamorelin Dosage Chart

Tesamorelin is dosed at 1 mg–2 mg daily by subcutaneous injection in educational protocols, typically at night. A 10 mg vial reconstituted with bacteriostatic water yields about 3.33 mg/mL. This information is for research and educational use only.

  • Reconstitute: Add 3.3 mL bacteriostatic water per 10 mg vial → ~3.33 mg/mL concentration.
  • Standard daily dose: 2 mg (2000 mcg) once daily subcutaneously (FDA-approved protocol).
  • Easy measuring: At 3.33 mg/mL,  1 unit = 0.01 mL ≈ 33.3 mcg on a U-100 insulin syringe.
  • Storage: Lyophilized: refrigerate at  2–8 °C (35.6–46.4 °F); reconstituted: refrigerate and use within 7 days with bacteriostatic water.

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.

Research context: For evidence on mechanisms, human and preclinical research, limitations, and safety.

  • Dosing & Reconstitution Guide

Educational guide for reconstitution and daily dosing

Standard FDA-Approved Protocol (3.0 mL = ~3.33 mg/mL)

WeekDaily Dose (mg / mcg)Units (per injection) (mL)
Week 11 mg / 1000 mcg30 units (0.30 mL)
Weeks 2–12+2 mg / 2000 mcg60 units (0.60 mL)

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

  • 1 . Draw 3.0 mL bacteriostatic water with a sterile syringe.
  • 2 . Inject slowly down the vial wall; avoid foaming.
  • 3 . Gently swirl until dissolved (do not shake).
  • 4 . Label and refrigerate at 2–8 °C (35.6–46.4 °F), protected from light.
  • 5 . Use within 7 days when reconstituted with bacteriostatic water.

  • 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 Range: 2 mg (2000 mcg) daily after Week 1 titration.
  • Reconstitution: 3.0 mL per 5 mg vial (~3.33 mg/mL) for accurate measurement.
  • Storage: Lyophilized refrigerated; reconstituted refrigerated up to 7 days; avoid freeze-thaw.
  • Dosing Protocol

FDA-approved daily dosing approach with tolerability titration.

  • Week 1: 1 mg (1000 mcg) once daily to assess tolerability.
  • Week 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 efficacy.

  • Lyophilized: Store at 2–8 °C (35.6–46.4 °F); newer formulations (Egrifta SV) stable at 20–25 °C (68–77 °F) before reconstitution.
  • Reconstituted (with bacteriostatic water): Refrigerate at 2–8 °C (35.6–46.4 °F); use within 7 days.
  • Reconstituted (with sterile water): Use immediately; discard any unused portion.
  • Do not freeze reconstituted solution; avoid repeated freeze-thaw cycles.
  • 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.
