What microdosing means

“Microdosing” refers to using doses below the standard 2.5 mg starting dose — often to minimize side effects, maintain results, or extend a vial. It is not an FDA-approved approach, and there is no official microdosing label; the figures below are community references only.

Because micro-doses are small, accuracy matters even more. A small change in BAC water shifts how many units a 1 mg dose becomes. Use the tirzepatide calculator to dial in a clean, readable number of units.
