Tirzepatide vial
The long view

Two pathways, one considered plan.

Tirzepatide is prescribed and monitored by a licensed clinician and reviewed over the long arc. If it is not right for you, a clinician will tell you.

What is it

Tirzepatide is a dual GIP and GLP-1 receptor agonist. It acts on two incretin receptors rather than one. It is compounded with glycine by a licensed 503A pharmacy and dispensed only after a clinician reviews your history.

How it works in the body

Acts on two receptors

Tirzepatide binds both the GIP and GLP-1 receptors, two incretin pathways the body uses in regulating blood sugar and appetite signalling.

Slows gastric emptying

It slows the rate at which the stomach empties, which is part of how the GLP-1 pathway signals fullness.

Prescribed and reviewed

Dosing is set by your clinician, started low, and reviewed over time for as long as you are treated.

Switching

Yes. You can transfer from another provider and continue on the same or an equivalent dose. This is confirmed during your medical intake so the clinician can prescribe the right dose for you.

How it’s made and tested

Compounded by a licensed 503A pharmacy and tested for potency and purity before it ships.
