Quickstart Highlights

Tesamorelin is a synthetic 44-amino-acid peptide analog of Growth Hormone-Releasing Hormone (GHRH) [1] . It stimulates endogenous growth hormone release and raises IGF-1 levels, leading to enhanced lipolysis and metabolic benefits [2] . Tesamorelin is FDA-approved for reducing visceral adipose tissue in HIV-associated lipodystrophy and is studied for metabolic disorders and aging research [3] [4] .

ReconstituteAdd 3.0 mL bacteriostatic water per 20 mg vial → ~6.67 mg/mL concentration.
Reference dose2 mg (2000 mcg) once daily subcutaneously (FDA-approved protocol).
Easy measuringAt ~6.67 mg/mL, 1 unit ~ 66.7 mcg ; 1 mg ~ 15 units and 2 mg ~ 30 units on a U-100 syringe.

Dosing & Reconstitution Guide

A practical calculator-ready setup based on the imported protocol reference. Use these values as a math starting point, then verify every entry against your own vial, diluent, and professional guidance.

Standard FDA-Approved Protocol (3.0 mL = ~6.67 mg/mL)

Phase / setup Dose & frequency Volume / units
Week 11 mg / 1000 mcg15 units (0.15 mL)
Weeks 2–12+2 mg / 2000 mcg30 units (0.30 mL)

2 mg (2000 mcg) once daily subcutaneously (FDA-approved protocol).

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.

Supplies Needed

Keep this as a planning checklist. TNHL does not sell or verify supplies on this page, and no supplier quality claims are made here.

Peptide Vials 8 weeks ≈ 6 vials (105 mg total)
  • 12 weeks ≈ 9 vials (161 mg total)
  • 16 weeks ≈ 11 vials (217 mg total)
Insulin Syringes Per week: 7 syringes (1/day)
  • 8 weeks: 56 syringes
  • 12 weeks: 84 syringes
  • 16 weeks: 112 syringes
Bacteriostatic Water Use 3.0 mL per vial for reconstitution.
  • 8 weeks (6 vials): 18 mL → 2 × 10 mL bottles
  • 12 weeks (9 vials): 27 mL → 3 × 10 mL bottles
  • 16 weeks (11 vials): 33 mL → 4 × 10 mL bottles
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

  • Goal: Reduce visceral adipose tissue and improve lipid profiles through sustained GH/IGF-1 elevation [3] [4] .
  • Schedule: Daily subcutaneous injections for 12–26 weeks (extendable to 52 weeks with medical supervision) [3] . Dose: 2 mg (2000 mcg) daily after Week 1 titration.
  • Reconstitution: 3.0 mL per 20 mg vial (~6.67 mg/mL) for accurate measurement.
  • 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) [7] [8] .
  • Frequency: Once per day (subcutaneous), preferably in the evening.
  • Cycle Length: 12–26 weeks; clinical trials support up to 52 weeks with monitoring [3] .
  • Timing: Evening administration recommended; rotate injection sites.

Storage Instructions

  • Lyophilized & Reconstituted: refrigerate at 2–8 °C (35.6–46.4 °F)
  • Storage: Lyophilized refrigerated; reconstituted refrigerated; avoid freeze-thaw.
  • Keep mixed and unmixed items clearly labeled so inventory and dose logs stay accurate.

04 · Good to know

Important Notes

  • Practical considerations for consistency and safety.
  • Use new sterile insulin syringes for each injection; dispose in a sharps container [10] .
  • Rotate injection sites (abdomen at least 2 inches from navel, thighs, upper arms) to reduce local irritation [6] [10] .
  • 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 [9] .
  • Document daily dose and site rotation to maintain consistency.

05 · How it works

How This Works

Tesamorelin is a synthetic 44-amino-acid peptide analog of Growth Hormone-Releasing Hormone (GHRH) [1] .

It stimulates endogenous growth hormone release and raises IGF-1 levels, leading to enhanced lipolysis and metabolic benefits [2] .

Tesamorelin is FDA-approved for reducing visceral adipose tissue in HIV-associated lipodystrophy and is studied for metabolic disorders and aging research [3] [4] .

The library page pairs that educational context with calculator-ready vial math, so users can understand the protocol structure and then track their own entered values in one place.

06 · Daily habits

Lifestyle Factors

  • Keep meals, training, sleep, and recovery notes in the journal so trends are easier to review.
  • Track body metrics only if they are relevant to the user's goal and approved data sources.
  • Use consistent timing and logging habits so adherence data is meaningful.

07 · What to expect

Potential Benefits & Side Effects

  • Tesamorelin observations should be recorded conservatively: expected research endpoints, tolerability notes, injection-site reactions when applicable, sleep, appetite, energy, mood, and any adverse or unusual response.
  • This section is not a claim of therapeutic benefit.

08 · Technique

Injection Technique

Pre-injection preparation
  • Wash hands with soap and water.
  • Wipe the vial stopper and chosen site with alcohol, then let both dry.
  • Confirm the vial concentration, calculator result, and intended draw amount before loading the syringe.
Injection procedure
  • Use the route and needle technique directed by a qualified professional or product instructions.
  • For subcutaneous injections, rotate sites and inject slowly to limit leakage and irritation.
  • Do not reuse needles or syringes.
Post-injection care
  • Dispose of sharps in a puncture-resistant container.
  • Return stored items promptly to the correct temperature.
  • Log dose, site, date, time, inventory change, and any observation.
