Enobosarm Dosing Calculator

Enobosarm (Ostarine/GTx-024): oral SARM for muscle preservation during GLP-1 weight loss.

Pre-filled with the most-reported clinical reconstitution protocol for Enobosarm. See how 1 mL and 2 mL of bacteriostatic water change concentration and syringe-draw volume, then adjust the calculator below for your own vial.

Quick answer · Clinical protocol

A 10 mg vial of Enobosarm reconstituted with 2 mL of bacteriostatic water yields a concentration of 5.00 mg/mL. At that concentration, a 3 mg dose of Enobosarm equals 60 units on a U-100 insulin syringe (0.600 mL). Enobosarm is typically administered once daily.

Enobosarm reconstitution: 1 mL vs 2 mL bac water

Bacteriostatic water volume is flexible. Less water means higher concentration and smaller injection volumes; more water means lower concentration and easier dose precision. Both options below are valid for a 10 mg vial.

Emerging protocol combining enobosarm with GLP-1 agonists to reduce lean mass loss during weight loss; mirrors QUALITY trial design

Lean Body Mass in Healthy Elderly (Phase 2)

Clinical
Dose
1 mg or 3 mg orally once daily. Both doses produced dose-dependent lean mass gains over 12 weeks.
Frequency
Once daily oral administration
Duration
12 weeks

The 3 mg dose produced greater lean mass gains and physical function improvement. ALT elevations were more common at 3 mg (20.8% in cancer trial).

Enobosarm reconstitution & storage

Enobosarm is an oral small molecule (not a peptide requiring reconstitution). It is administered as a capsule or tablet and does not require injection or reconstitution.

Oral formulation. Specific storage conditions for the clinical trial formulation have not been publicly disclosed. Small molecules typically stored at controlled room temperature (15-30 degrees C) protected from moisture.

Enobosarm dosing FAQ

How much bacteriostatic water should I add to a 10 mg vial of Enobosarm?

The community standard is 2 mL of bacteriostatic water for a 10 mg Enobosarm vial. That gives a concentration of 5.00 mg/mL, so a 3 mg dose is 60 units on a U-100 insulin syringe. Adding 1 mL instead doubles the concentration to 10.00 mg/mL and halves the draw to 30 units. Less water = smaller injection volume but harder to measure precisely.

How many syringe units is a 3 mg dose of Enobosarm?

On a standard U-100 insulin syringe, a 3 mg dose of Enobosarm is 60 units when the 10 mg vial is reconstituted with 2 mL of bacteriostatic water (5.00 mg/mL). If you use 1 mL of bac water instead, draw 30 units (10.00 mg/mL).

What is the standard Enobosarm dose?

Clinical protocols for Enobosarm typically use 3 mg once daily via subcutaneous injection. 3 mg is a common starting dose. FDA confirmed 3 mg as an acceptable dosage for further development. The 3 mg dose produced 0% lean mass loss and 100% fat mass loss when combined with semaglutide.

How long does a vial of Enobosarm last at 3 mg once daily?

A 10 mg vial of Enobosarm contains roughly 3 doses at 3 mg per injection. At once daily dosing, that is approximately 3 days (about 0 weeks) of supply per vial. Reconstituted Enobosarm should generally be used within 28 days when refrigerated.

Where do you inject Enobosarm?

Enobosarm is typically administered subcutaneously. Common subcutaneous sites are the lower abdomen (at least an inch from the navel), the outer thigh, and the love handles. Rotate sites with each injection to reduce localized irritation and bruising.

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

Bacteriostatic water (containing 0.9% benzyl alcohol as a preservative) is strongly preferred for multi-dose vials like Enobosarm 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.
