Semaglutide dosage guide

Semaglutide dosage reference: typical range 0.25 – 2.4 mg, 1× per week (same day), cycle Continuous (titrate up over months); 4-week titration phases…

FDA-approved GLP-1 agonist that has transformed weight loss medicine. Mimics glucagon-like peptide-1 to reduce appetite, slow gastric emptying, and improve insulin sensitivity.

Published protocol literature for Semaglutide describes a typical range of 0.25 – 2.4 mg, dosed 1× per week (same day), over a cycle of Continuous (titrate up over months); 4-week titration phases. Reported half-life: approximately 7 days.

Semaglutide titration chart

Protocols are usually titrated rather than started at the top of the range. The tiers below reflect how Semaglutide dosing is commonly stepped in the published protocol literature.

Reconstitution and concentration

Concentration in mcg/mL equals vial milligrams multiplied by 1000, divided by the millilitres of bacteriostatic water added. Volume per dose in mL equals the target dose in mcg divided by that concentration. On a U-100 insulin syringe, multiply the volume in mL by 100 to read the units.

Frequently asked questions

What is a typical Semaglutide dosage?

Published protocol literature for Semaglutide generally describes 0.25 – 2.4 mg, administered 1× per week (same day). Individual protocols vary and should be set by a licensed practitioner.

How often is Semaglutide dosed?

1× per week (same day). Frequency is driven by half-life — Semaglutide has a reported half-life of approximately 7 days, so shorter-acting compounds are dosed more often.

How long is a Semaglutide cycle?

Typical cycle length reported is Continuous (titrate up over months); 4-week titration phases. Cycling exists to limit receptor desensitisation and to create assessment windows, not as a fixed rule.

How do you reconstitute Semaglutide?

2mg → 1ml bacteriostatic water; 5mg → 2ml bacteriostatic water; 10mg → 2ml bacteriostatic water. Concentration in mcg/mL equals vial milligrams times 1000 divided by millilitres of bacteriostatic water.

How is semaglutide different from tirzepatide?

Semaglutide targets the GLP-1 receptor alone. Tirzepatide is a dual GIP/GLP-1 receptor agonist, hitting two incretin pathways at once.

Do I need a prescription for clinical use?

Yes. Any clinical use must be directed by a licensed medical practitioner. Research-use product is supplied for investigational purposes only.
