1.75 mg of semaglutide in units
At 5 mg/mL it is 35 units on a U-100 insulin syringe. At any other concentration it is a different number — here is the full table, and a calculator for your exact vial.
This is arithmetic, not a prescription. It converts a dose someone already prescribed you into syringe units. It does not tell you what dose to take, and it cannot know what is in your vial. Read the concentration off the vial in your hand every single time — not the last one, not the one in the photo on the pharmacy's website.
How many units is 1.75 mg of semaglutide?
There is no single answer, and any page that gives you one without asking about your vial is wrong. 1.75 mg is a mass. Units are a volume marking. What converts one to the other is the concentration of your specific vial, in milligrams per millilitre.
At the concentrations compounding pharmacies actually use, 1.75 mg of semaglutide works out as:
| Vial concentration | Units on a U-100 syringe | Volume | Typical vial |
|---|---|---|---|
| 1 mg/mL | 175 units over one syringe | 1.75 mL | 1 mg in 1 mL |
| 2 mg/mL | 87.5 units | 0.875 mL | 4 mg in 2 mL |
| 2.5 mg/mL | 70 units | 0.7 mL | 5 mg in 2 mL |
| 4 mg/mL | 43.75 units | 0.438 mL | 8 mg in 2 mL |
| 5 mg/mL | 35 units | 0.35 mL | 5 mg in 1 mL, or 10 mg in 2 mL |
| 10 mg/mL | 17.5 units | 0.175 mL | 10 mg in 1 mL, or 20 mg in 2 mL |
Concentration = total mg in the vial ÷ total mL after reconstitution. Both numbers are on the vial or the pharmacy paperwork. A U-100 syringe is marked so 100 units = 1 mL, so one unit is 0.01 mL.

Prefilled with 1.75 mg. Change it if you are checking a different step.
Reading it on the syringe
That lands exactly on the 35-unit marking, which is the easiest case to draw accurately.
Insulin syringes are marked in units, not millilitres, and the two are easy to confuse under pressure. On a U-100 syringe the barrel runs 0 to 100 units over 1 mL. If your syringe is marked U-40 or U-50 — uncommon in GLP-1 kits, but they exist — the same volume is a different number of units, and this table does not apply. Check the barrel.
Where 1.75 mg sits in a semaglutide schedule
1.75 mg is an intermediate micro-titration waypoint between Wegovy's 1.7 mg and 2.4 mg maintenance doses. For patients sensitive to rapid dose escalation, measuring 1.75 mg from a compounded vial provides smoother appetite suppression without gastrointestinal shock.
Brand-name Ozempic, Wegovy and Rybelsus pens are dialled or preset in milligrams and never drawn into a syringe, so none of this conversion applies to them. This page is for compounded vials. If you want to see the whole escalation with dates attached, the titration schedule tool maps it out.
The mistake that sends people to hospital
In July 2024 the FDA alerted providers and patients that people using compounded injectable semaglutide had administered five to twenty times the intended dose. The cause was not recklessness. It was that milligrams, millilitres and insulin syringe units are three different quantities, and a vial label only tells you one of them.
Here is the whole trap in one line: a 5 mg vial reconstituted into 1 mL and a 5 mg vial reconstituted into 2 mL carry the same number on the label and need completely different syringe volumes for an identical prescribed dose. One is 5 mg/mL, the other is 2.5 mg/mL. Draw the same units from both and one of them is double.
Two habits prevent nearly all of it. Confirm the concentration on the specific vial before every draw, and re-check the number when you change pharmacy, batch or refill — concentrations are not standardised between compounders and can change without anything on the outside of the box looking different.
