Pick the vial, the water you added and the dose. Get the exact draw in units for the syringe in your hand.
Step 1 of 4
This vial holds 10 mg in total.
U-100 insulin syringe · 1 mL · lines every 2 units · 1 unit = 0.01 mL
80.0 units on a U-100 insulin syringe · 1 mL · lines every 2 units, which is 0.80 milliliters. The draw lands on a syringe line.

Mazdutide is a once-weekly injection that works on two hormone receptors at once, GLP-1 and glucagon. It is the same class idea as tirzepatide, with a different second target. In China it is prescribed for weight and for type 2 diabetes. Everywhere else it is sold online to people who want the newest weight-loss injection.
The trial program is large, and every trial in it was run in China. Two phase 3 trials compared it against placebo and reported substantial weight reduction. An independent review of nine trials says longer-term, multi-ethnic data is still needed. Nobody outside a Chinese pharmacy is getting the approved product.
Each row starts with the same 10 mg vial and changes only the amount of water. More water makes the mixture less concentrated, so the same dose uses more syringe units.
| Water added | Concentration | Per U-100 unit | Draw for 4 mg | Nearest syringe line |
|---|---|---|---|---|
| 1 mL | 10.00 mg/mL | 100.0 mcg | 40.0 u · 0.400 mL | exactly 40 u |
| 2 mL | 5.00 mg/mL | 50.0 mcg | 80.0 u · 0.800 mL | exactly 80 u |
The vial, water and dose shown here are the calculator’s starting example for Mazdutide. Replace them with your own values. Every result in the table is calculated from those inputs.
Only one mazdutide vial is published here, because no source this project reached names a strength for it at all. At the amount the tool opens on, both water volumes work and both land on a syringe line. Above that amount, one of them stops fitting the barrel.
Each listed water volume gives a draw that lands on a syringe line, with nothing to judge between two lines. That comes from these exact numbers, not from the compound itself.
It stops holding the moment the amount changes. The trials went well above what the tool opens on, and the clean reading does not survive the climb.
Mix this vial into the larger listed volume and the upper studied amounts need more liquid than a U-100 syringe holds. The top one needs close to two barrels.
So the habit of adding water for an easier read works against you here as the amount rises. The stronger mix is the one that keeps an injection to a single draw.
Most vial ladders on this site come from what sellers converge on. This one does not, because nothing checkable names a strength for mazdutide.
The size here was chosen to cover every amount the trials used, and it is a worked example rather than a claim that such a vial is sold. Anyone holding a different strength should type it in.
Every other unapproved compound in this tool is unapproved everywhere. Mazdutide is not. It is licensed and dispensed in China, so the amount typed here has a standing nothing else in this registry shares. That standing stops at the border, and the rest of this page is about what it does and does not buy you.
An approval is a regulator reading a dossier and agreeing to a product, a use and a group of patients. China did that. The agency that governs an American pharmacy has not, and holds no document about this compound at all.
An approved product comes with an approved schedule, and that schedule exists in Chinese. This project has not read it, cannot reach it at an address it could check, and will not transcribe a document nobody opened.
Most of this tool rewards adding water. A weaker solution spreads a small mass across more barrel, and small amounts get easier to read that way.
Compounds here usually get their vial ladder from what sellers converge on, corroborated across catalogs. Nothing this project reached names a strength for this compound at all.
Mix 10 mg into 2 mL and one U-100 unit carries 50.0 mcg. The table shows how much peptide is in each numbered syringe line. These are conversion examples, not suggested doses.
| U-100 line | Volume | Mass (mcg) | Mass (mg) |
|---|---|---|---|
| 10 u | 0.10 mL | 500 mcg | 0.5 mg |
| 20 u | 0.20 mL | 1,000 mcg | 1 mg |
| 30 u | 0.30 mL | 1,500 mcg | 1.5 mg |
| 40 u | 0.40 mL | 2,000 mcg | 2 mg |
| 50 u | 0.50 mL | 2,500 mcg | 2.5 mg |
| 60 u | 0.60 mL | 3,000 mcg | 3 mg |
| 70 u | 0.70 mL | 3,500 mcg | 3.5 mg |
| 80 u | 0.80 mL | 4,000 mcg | 4 mg |
| 90 u | 0.90 mL | 4,500 mcg | 4.5 mg |
| 100 u | 1.00 mL | 5,000 mcg | 5 mg |
The math is only one part of the question. These guides cover the compound, published doses, side effects, mixing steps and supplies.
