Tirzepatide Vial Sizes Compared
Tirzepatide GLP-2
How to compare tirzepatide fills from any catalog: milligrams, cost per mg, and the lot report for that exact size.

What we carry
We list tirzepatide as Tirzepatide GLP-2, a lyophilized research vial in Metabolic, in one size: 20mg. Tirzepatide is a 39-amino-acid peptide and the active ingredient in prescription medicines; the vial here is research material sold for laboratory use only.
| Vial | Price | Per mg |
|---|---|---|
| Tirzepatide GLP-2 20mg | $75.00 | $3.75/mg |
How to compare any two fills
- Same compound: a bigger tirzepatide vial is more material in one bottle, not a stronger version.
- Cost per mg: divide the price by the milligrams on the label. That's the fair way to line up two sizes or two catalogs.
- Lot report for that size: a report covers one lot and one fill. Check that it names the size you're buying and shows the amount the lab measured. How to read a COA covers what to look for.
- Up-front cost: larger fills cost more at once and mean fewer vials to open.
Concentration is arithmetic
Concentration depends on the volume, not the label size. For the same 2 mL, the numbers work out like this:
| Fill | Volume | mg/mL |
|---|---|---|
| 10mg | 2 mL | 5 mg/mL |
| 20mg (we stock this) | 2 mL | 10 mg/mL |
| 30mg | 2 mL | 15 mg/mL |
The reconstitution calculator does the same math for any mass and volume. It's bench arithmetic, not a method or a protocol.
Looking for a different size?
The 20mg vs 30mg question has its own page: Tirzepatide 20mg vs 30mg. The only Metabolic card here with several fills is Reta GLP-3 (20mg, 30mg, 50mg), and that's retatrutide, a different compound. See Reta GLP-3 vs Tirzepatide GLP-2. If you'd like us to list another tirzepatide size, tell us on the request page.
Testing notes
Tirzepatide GLP-2 is listed as third-party tested. We haven't posted a lot report for it on the site yet; when we do, it appears on the product page.
Quick answers
What tirzepatide sizes do you carry?
One: Tirzepatide GLP-2 20mg. If you'd like a different fill, tell us on the request page.
Is a bigger tirzepatide vial stronger?
No. A bigger fill is more of the same compound in one bottle. Concentration is set by the volume, not the label.
How should I compare tirzepatide prices between catalogs?
Divide the price by the milligrams to get cost per mg, then check that the lot report matches that exact size and lists the amount the lab measured.
