Route

Subcutaneous

Reduced frequency for long-term use; some users find 5 days on, 2 days off sufficient to maintain results

Dose

1-2 mg tesamorelin + 200 mcg ipamorelin

Frequency

Once daily before bed

Duration

12-16 weeks

Route

Subcutaneous

Combines GHRH analog with GHRP for enhanced GH output; less common due to tesamorelin cost

Duration

Ongoing; reassess periodically based on clinical response

Inject into abdomen. Rotate injection sites. This is the only FDA-approved dosing regimen.

Dose

2 mg subcutaneous injection

Frequency

Once daily

Duration

12 months in the GILT trial

Investigational use only. Same dose as approved indication used in clinical research for hepatic steatosis.

How much bacteriostatic water should I add to a 5 mg vial of Tesamorelin?

The community standard is 2 mL of bacteriostatic water for a 5 mg Tesamorelin vial. That gives a concentration of 2.50 mg/mL, so a 2 mg dose is 80 units on a U-100 insulin syringe. Adding 1 mL instead doubles the concentration to 5.00 mg/mL and halves the draw to 40 units. Less water = smaller injection volume but harder to measure precisely.

How many syringe units is a 2 mg dose of Tesamorelin?

On a standard U-100 insulin syringe, a 2 mg dose of Tesamorelin is 80 units when the 5 mg vial is reconstituted with 2 mL of bacteriostatic water (2.50 mg/mL). If you use 1 mL of bac water instead, draw 40 units (5.00 mg/mL).

What is the standard Tesamorelin dose?

Community-reported protocols for Tesamorelin typically use 2 mg once daily via Subcutaneous. 2 mg is a common starting dose. FDA-approved dose for HIV lipodystrophy; adopted by community for general visceral fat reduction. Injected in abdominal area before bed.

How long does a vial of Tesamorelin last at 2 mg once daily?

A 5 mg vial of Tesamorelin contains roughly 2 doses at 2 mg per injection. At once daily dosing, that is approximately 2 days (about 0 weeks) of supply per vial. Reconstituted Tesamorelin should generally be used within 28 days when refrigerated.

Where do you inject Tesamorelin?

Tesamorelin is typically injected subcutaneous. Common sites reported in the literature and by users include: Subcutaneous (abdomen only per FDA-approved labeling). Rotate sites with each injection to reduce localized irritation.

Can I use sterile water instead of bacteriostatic water for Tesamorelin?

Bacteriostatic water (containing 0.9% benzyl alcohol as a preservative) is strongly preferred for multi-dose vials like Tesamorelin because it inhibits microbial growth and lets a single vial be used over multiple weeks. Sterile water has no preservative and should generally be reserved for single-use preparations only.
