Peptide Calculator

Know the concentration.
Check the syringe mark.

Vial and dose math, with the evidence and limits plainly stated.

Your vial & syringe

Use the amounts on your own label. This tool calculates quantities; it does not select a treatment or dose.

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

FDA approved as a specific ready-to-use autoinjector for the labeled indication. Source

No general vial-size preset is documented here. Enter your own labeled amounts.

Documented: 1.75 mg · Subcutaneous — labeled ready-to-use autoinjector · As needed, at least 45 minutes before anticipated activity; no more than once per 24 hours or 8 doses per month. Dose source

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.
