Compounded Semaglutide Dosage Chart: mg to Units (All Concentrations)

The compounded semaglutide dosage chart converts your prescribed mg dose into units on a U100 insulin syringe based on your vial's concentration. At the most common 5 mg/ml concentration, the standard 0.25 mg starting dose is 5 units, 0.5 mg is 10 units, 1.0 mg is 20 units, 1.7 mg is 34 units, and 2.4 mg (Wegovy maximum) is 48 units. Concentrations vary by compounding pharmacy, so always verify your vial label.

The Complete Compounded Semaglutide Dose Chart

Below is the full compounded semaglutide dosage chart for the three most common compounding pharmacy concentrations. Each row shows the standard FDA-approved Wegovy titration step in mg, with the corresponding unit count on a U100 insulin syringe.

Here is what to know up front about this semaglutide units chart. The formula is: Units = (mg dose ÷ concentration) × 100. The 5 mg/ml concentration is the most common in US compounding pharmacies as of 2026. The FDA-approved maximum is 2 mg per week for Ozempic and 2.4 mg per week for Wegovy. Doses above 2.4 mg are not FDA-approved and have limited long-term safety data. The math follows FDA Wegovy prescribing information. For broader conversion logic, see how many mg in a ml.

The Standard Semaglutide Titration Schedule

The semaglutide dosing chart follows the FDA-approved Wegovy titration schedule. Patients gradually increase the dose every 4 weeks to allow the body to adjust and minimize GI side effects.

For Ozempic (type 2 diabetes), the titration is similar but maxes out at 2 mg weekly. The standard Ozempic titration moves through 0.25, 0.5, 1.0, and 2 mg weekly. For broader semaglutide dosing details, see compounded semaglutide dosage.

How to Use the Compounded Semaglutide Dose Chart

Using the semaglutide dose chart requires three pieces of information:

1. Your prescribed mg dose. This comes from your physician and follows the titration schedule. Common doses are 0.25, 0.5, 1.0, 1.7, 2.0, and 2.4 mg.

2. Your vial's concentration. This is printed on the label. Most US compounded semaglutide is dispensed at 5 mg/ml. Less common are 2.5 mg/ml and 10 mg/ml.

3. Your syringe type. All conversions on this chart assume a U100 insulin syringe (100 units per ml). If you have any other syringe, contact your pharmacy before using the chart.

Look up your dose row, find your concentration column, and read the unit count. For example, 1.0 mg at 5 mg/ml = 20 units.

The Math Behind the Chart

The compounded semaglutide dosage chart uses this formula:

Units = (mg dose ÷ concentration in mg/ml) × 100

Worked example: 1.7 mg at 5 mg/ml.

1.7 ÷ 5 = 0.34 ml 0.34 × 100 = 34 units

The same dose at 2.5 mg/ml: 1.7 ÷ 2.5 = 0.68 ml = 68 units

The same dose at 10 mg/ml: 1.7 ÷ 10 = 0.17 ml = 17 units

The volume changes with each concentration, but the mg dose stays the same. For more on the underlying math, see how many mg in a ml.

Why Concentrations Vary Across Pharmacies

Compounding pharmacies dispense semaglutide at different concentrations based on their formulation choices.

2.5 mg/ml provides good measurement precision for small doses. The starting 0.25 mg dose becomes 10 units, easier to read precisely than 5 units at 5 mg/ml.

5 mg/ml is the most common concentration in 2026. It balances volume and precision well across the entire titration range.

10 mg/ml packs more drug into less liquid, useful for higher doses. The downside is reduced precision at small doses (0.25 mg = only 2.5 units, hard to read accurately).

Different pharmacies make different choices. Always verify the concentration on your specific vial.

Reverse Conversion: Units to mg

The same chart works in reverse if you know your units and want to confirm your mg dose. For full guides, see individual articles:

• 20 units of semaglutide is how many mg

• 40 units of semaglutide is how many mg

• 50 units of semaglutide is how many mg

Safety Notes for Higher Doses

Doses above 2.4 mg per week are not FDA-approved. Some compounded protocols use 2.5 mg, 3 mg, or higher for patients who plateau on the maximum approved dose. These higher doses:

• Have limited long-term safety data

• May increase nausea, vomiting, and GI side effects

• Carry higher risk for pancreatitis and gallbladder issues

• Should only be used under direct physician supervision

Patients on doses above 2.4 mg should have more frequent monitoring, including blood work and physician check-ins.
