Dosing

Unopened tirzepatide needs a fridge (36-46°F). Once in use, most pens/vials tolerate room temp for 21-30 days. Here's the FDA-sourced breakdown by product.

Tirzepatide can curb appetite within days, but real weight loss and A1C drops build over 4 to 9 months. Here's the week-by-week timeline from trial data.

How to reconstitute compounded tirzepatide correctly: BAC water ratios, mixing technique, storage times, and the mistakes that ruin a vial. Step-by-step guide.

There's no fixed tirzepatide cycle. SURMOUNT trials ran 36-72 weeks continuously. Here's what the data says about duration, titration, and stopping.

Tirzepatide starts at 2.5mg weekly and titrates to a 15mg max. Here's the full FDA schedule from SURMOUNT and SURPASS, with real numbers on timing and side effects.

A tirzepatide dosage calculator only converts mg to mL and units. See the real FDA titration schedule (2.5mg to 15mg) and how to check any calculator's math.

Tirzepatide's half life is about 5 days, per FDA labeling. See what that means for dosing intervals, missed doses, washout time, and drug clearance.

Tirzepatide is injected subcutaneously once weekly. Here's the full injection protocol: needle size, sites, angle, rotation, and what the SURMOUNT trials actually used.

Abdomen, thigh, or upper arm: the FDA label allows all three. Here's the injection site rotation schedule that actually cuts down on skin reactions.

Unopened tirzepatide stays cold (2-8°C) until the expiration date; in-use pens last 21-31 days at room temp. Here's what the labels actually say.
