Semaglutide Compound Dosage: Charts, Units, and Titration Schedules

There is no single standard semaglutide compound dosage. A prescriber sets the dose in milligrams, most people start at 0.25 mg once a week and increase about every four weeks, and the number of units you draw depends entirely on how concentrated your vial is. Two vials holding the same milligram dose can require completely different syringe volumes.

Semaglutide Compound Dosage: Milligrams First, Units Second

Compounded semaglutide is usually dispensed as a liquid in a vial with a concentration printed on the label, such as 2.5 mg/mL or 5 mg/mL. Three numbers matter:

• Milligrams (mg): the actual amount of semaglutide, which is what your prescriber titrates.
• Milliliters (mL): the volume of liquid that delivers that amount.
• Units: the markings on a U-100 insulin syringe, where 1 mL equals 100 units.

A semaglutide compound dosage in units means nothing without the concentration attached to it. The same 0.5 mg dose is 10 units from a 5 mg/mL vial and only 5 units from a 10 mg/mL vial.

Typical Semaglutide Compound Dosing Schedule

Many clinicians model compounded treatment on the same titration used by FDA-approved Wegovy (semaglutide). Doses go up only when side effects are tolerable.

Phase	Weekly dose	Typical duration
Start	0.25 mg	4 weeks
Step 2	0.5 mg	4 weeks
Step 3	1 mg	4 weeks
Step 4	1.7 mg	4 weeks
Maintenance	2.4 mg	Ongoing

Not everyone follows that pace. Some providers hold a dose for eight weeks, some stop at 1.7 mg, and some use a slower ramp for people who are sensitive to nausea. Most pharmacies publish their own compound semaglutide doses, and those schedules are a starting framework rather than a prescription.

Semaglutide Compound Doses Chart by Concentration

Use the concentration printed on your own vial. The table below converts common weekly doses into units on a U-100 syringe.

Weekly dose	2.5 mg/mL	5 mg/mL	10 mg/mL
0.25 mg	10 units	5 units	2.5 units
0.5 mg	20 units	10 units	5 units
1 mg	40 units	20 units	10 units
1.7 mg	68 units	34 units	17 units
2.4 mg	96 units	48 units	24 units

A semaglutide 5mg/ml dosage chart is the version most people run into, because 5 mg/mL is a common compounded strength. If your vial is labeled 2 mg/mL, 8 mg/mL, or something else, the unit numbers change again and should be recalculated.

Why Compounded Doses Vary So Much

Compounding pharmacies are not required to match the concentration of brand-name products, and many choose a concentration that makes low starting doses easier to measure. Other factors shift the math too:

• Added ingredients. A semaglutide b12 compound mixes semaglutide with vitamin B12, which changes the total volume but not the semaglutide content per milligram.
• Concentration choices. Vials are commonly offered at 1 mg/mL, 2.5 mg/mL, 5 mg/mL, or 10 mg/mL.
• Combination formulas. Unapproved products that pair semaglutide with other peptides do not follow the same dosing logic as semaglutide alone.
• Regulatory changes. The compound semaglutide ban landscape shifted after the FDA resolved the semaglutide shortage in February 2025, so availability and formulations vary by pharmacy and state.

Semaglutide vs Tirzepatide: Dosing at a Glance

Many people researching options look at tirzepatide vs semaglutide dosage for weight loss, because the two drugs titrate very differently. Tirzepatide (Mounjaro, Zepbound) starts at 2.5 mg weekly and can reach 15 mg, while semaglutide starts at 0.25 mg and tops out at 2.4 mg for weight management.

Feature	Semaglutide	Tirzepatide
Starting weekly dose	0.25 mg	2.5 mg
Typical maintenance dose	1.7–2.4 mg	5–15 mg
Titration step	Every 4 weeks	Every 4 weeks
Maximum weekly dose	2.4 mg (weight management)	15 mg
FDA-approved as a compounded product	No	No

Milligram numbers are not interchangeable between the two drugs. Switching products requires a new prescription and a fresh syringe calculation.

Safety and Legal Reality Check

Compounded semaglutide is not FDA-approved, and it has not been reviewed for safety, effectiveness, or manufacturing quality the way Ozempic, Wegovy, and Rybelsus have. The FDA has warned about dosing errors involving compounded semaglutide, including cases where people injected five to ten times the intended amount after confusing milligrams with units.

Common side effects include nausea, vomiting, diarrhea, constipation, and abdominal pain, and they are most likely right after a dose increase. More serious risks include pancreatitis, gallbladder disease, kidney injury from dehydration, and a boxed warning about thyroid C-cell tumors.

Dose increases should only happen under a prescriber's direction. Never change your dose based on someone else's chart, a social media post, or a friend's results.

What to Confirm Before You Inject

1. Confirm the concentration on the vial in mg/mL.
2. Confirm the prescribed dose in mg.
3. Convert to units for your syringe size and ask the pharmacist to double-check the math.
4. Use a new needle each time and never share vials.
5. Report persistent vomiting, severe abdominal pain, or vision changes right away.

Talk with a licensed healthcare professional, ideally one who manages GLP-1 therapy regularly, before starting, stopping, or adjusting any compounded semaglutide dose.

COMMON QUESTIONS

Frequently Asked Questions

How many units is 0.25 mg of compounded semaglutide?

It depends on the concentration printed on your vial. At 5 mg/mL, 0.25 mg equals 5 units on a U-100 syringe; at 2.5 mg/mL it equals 10 units; at 10 mg/mL it equals 2.5 units. Confirm the conversion with your pharmacist before injecting.

Is compounded semaglutide dosed the same as Ozempic or Wegovy?

The milligram titration often looks similar, since many providers follow the same 0.25 mg to 2.4 mg ramp used by Wegovy. The units are usually different, however, because compounded vials come in different concentrations. Compounded semaglutide is also not FDA-approved.

Can I still get compounded semaglutide in the United States?

It depends on your state and pharmacy. The FDA declared the semaglutide shortage resolved in February 2025 and set enforcement dates that sharply limit large-scale compounding of semaglutide, though some state-licensed pharmacies still operate under narrower exceptions. Check current availability with a pharmacist and your prescriber.
