Is compounded semaglutide the same as ozempic

You are looking into lower-dose or compounded routes.

Reference and calculator, not medical advice. Dosing figures below are transcribed from FDA-approved prescribing information and link back to it. Last reviewed August 2026.

They are not the same product, and the difference is regulatory rather than cosmetic. An approved product went through the FDA review that produced the prescribing information this site quotes from; a compounded preparation is made by a pharmacy and has no such document behind it. That is why every dosing figure here comes from the approved label — for the compounded version, the equivalent document does not exist.

Compounded vs brand-name: what actually differs

Current as of August 2026.

Compounded is usually cheaper but can change with the rules; brand-name costs more and is more predictable. Worth raising with whoever writes your prescription. FDA’s compounding pages have the detail if you want it.

mg → syringe units converter

U-100 syringe. Formula: (dose ÷ concentration) × 100.

12.5units on a U-100 syringe
= 0.125 mL  ·  2.5 mg at 20 mg/mL

Check the concentration printed on the vial you are actually holding. The same dose in milligrams is a completely different mark on the syringe at a different concentration. If the number here does not match what your prescriber told you, trust your prescriber.

Where a compounded product is lawfully supplied, it may come at a concentration that differs from the branded pens — and that is precisely where the milligram-to-units arithmetic goes wrong. Convert using the concentration printed on the vial you are holding, never a figure from a forum post.

Common questions

Is microdosing an approved dosing strategy?
No. It is not a labelled regimen. The prescribing information defines a stepped schedule with a specified starting dose; anything below that is off-label and a decision for a prescriber.

Sources and last review

Every dosing figure on this page is transcribed from an FDA-approved label and links back to it. Conversions are arithmetic you can repeat by hand. Nothing here is reviewed by a clinician, and this site does not employ one — which is exactly why what I do publish stays traceable to its source.

Transcribed from the labels above and checked by me — Gavin, who builds this site, takes a GLP-1, and is not a clinician. Last reviewed August 2026. Found an error? [email protected] — I treat corrections as bugs. How this site is built and funded.
