FDA-approved drug — specific formulations and indications Evidence and cautions

FDA approved for a specific HIV-associated lipodystrophy indication and formulation. Source

Labeled 11.6 mg vial with 1.3 mL supplied water; final concentration 8 mg/mL; 7 labeled doses. Preset source

Documented: 1.28 mg · Subcutaneous — only the 11.6 mg vial formulation · Once daily Dose source

The labeled tesamorelin formulation has a specific final concentration that differs from simple vial mass divided by water added. The matching preset uses the label’s final concentration and usable supply. Other entries cannot substitute for this formulation. Read the label.

Math assumes the entered liquid volume is the final solution volume; powder displacement, overfill and wastage are not modeled. Follow product-specific preparation instructions.

Which peptides have been studied?

Explore by goal. Ordered by evidence type, not by expected benefit. A study is not a recommendation; check the population, route and limitations.

Semaglutide

Daily protein target: Not set. Cellular Bloodwork Analysis →

Protein & resistance training: Include regular resistance training suited to your ability, alongside adequate protein, to help protect muscle while weight comes off.

Starting-dose comparison: 0.025–0.05 mg — 10–20% of the 0.25 mg labeled starting dose.

Adult weight reduction · subcutaneous injection · once weekly. Labeled starting period: Weeks 1–4 · starting dose.

Typical cycle: No micro-dose on/off cycle is specified in Dr. Axe’s material.

Dr. Axe’s educational position is to explore 10–20% of the standard labeled dose. This is arithmetic, not an FDA-labeled regimen or a proven equivalent treatment. This tool does not tell you to cut or change your prescription.
