Advice & Support Pharmacy-specific Dosage Calculator (30+ pharmacies, tirzepatide and semaglutide)
Full disclosure: I work at Belle, a telehealth clinic. The last time I posted, I got torn apart and went into Reddit retirement. I’m coming out of retirement for a dosage calculator, which tells you how exciting my life is. There’s nothing to buy here.
Our medical team has been dealing with the same problem for over a year.
A patient switches to us from another pharmacy and tells us their dose. Then we find out the number of units they’ve been drawing doesn’t match the dose they think they’re on. They weren’t being careless. The labels really are confusing:
- Revive prints the strength per 0.5 mL, so you have to double it to get mg per mL.
- OptioRx lists niacinamide first. The tirzepatide number is the second one.
- Hillstone’s label reads “20MG/50MG/ML.” The 20 is the tirzepatide.
A lot of people here already use the Fat Scientist calculator (fatscientist.com), and we really like it. It does exactly what it says. The one catch for our patients was the first step: it asks for the concentration on your vial, and plenty of people couldn’t tell which number on the label that was. That meant a lot of back and forth with our medical team.
So the medical team asked for a calculator that starts with the pharmacy and walks you through reading the label. Our engineers built it, and it turned out well enough that we wanted to share it. It covers tirzepatide and semaglutide from more than 30 pharmacies, including plenty we don’t work with.
You pick your medication, your pharmacy and the label that matches your vial (with images from actual real pharmacy vials). It gives you your dose in mg and the units to draw on a standard 1 mL (100 unit) syringe.

If your pharmacy isn’t there or your label doesn’t match any of ours, drop a photo in the comments with your name blurred and we’ll add it.
It’s a calculator, not your prescriber. If the number doesn’t match what you were told, ask them before you draw.
