The math
How the per-mg price is calculated
A Tirzepatide vial holds 20mg. Divide the vial price by 20 to get the cost per mg. This lets you compare it against any other source on a like-for-like basis.

Per-mg figures are price math only. They are not a dose recommendation. The Research Reference included with your order is educational, not a prescription. Consult a licensed physician for medical decisions.
Research context
What does the per-mg price mean for research use?
Per-mg pricing exists so a lab can compare the cost of material on a like-for-like basis, independent of vial size. Tirzepatide is a dual GIP and GLP-1 receptor agonist that was studied in the Phase 3 SURMOUNT-1 obesity trial at once-weekly maintenance doses of 5 mg, 10 mg, and 15 mg, with the 15 mg arm reaching up to about 22.5 percent mean body-weight reduction over 72 weeks (Jastreboff et al., NEJM 2022).
Those figures describe what the trial measured, not a dose for any person. A 20mg vial at $4.60 per mg is a statement about the cost of the raw compound and nothing more. The Research Reference included with an order is educational, the material is sold for research purposes only, and a qualified clinician sets any personal plan. For what the trials reported, see the tirzepatide dosage page.

Tirzepatide is in a research stack
A stack groups catalog compounds from one research area and is priced at 35 percent off their combined retail. It is a grouping for browsing related research, not a protocol, and no stack has been tested as a combination.
