Compounded Tirzepatide with Glycine and B12
From $180/mo*
Activates both GLP-1 and GIP receptors, the two gut hormones that signal appetite and satiety. Personalized ingredients like Glycine and B12 may support muscle maintenance and nutrient deficiencies during a caloric deficit.
*Billed quarterly with a three-month commitment paid up front.
WHY GLP-1S
Natural hormone breaks down in minutes. GLP-1s last days.
Natural GLP-1 lasts ~2 minutes
Every time you eat, your gut releases a hormone called GLP-1 that signals fullness, triggers insulin release, and slows digestion. An enzyme called DPP-4 destroys it within 1 to 2 minutes.

Published study facts
Engineered to last longer
GLP-1 receptor agonists are lab-engineered versions of this hormone, modified to resist DPP-4 breakdown and stay active long enough to sustain appetite control and blood sugar regulation.

Sustained effects: minutes to days
The result: half-lives ranging from 2.5 hours to approximately 7 days — up to 5,000 times longer than the natural hormone.

HOW GLP-1 RA WORKS
Supports feeling fuller for longer
Tirzepatide is a GLP-1 receptor agonist that mimics the GLP-1 hormone produced in the gut. Receptors are located in the brain, gut, heart, and pancreas, where activation supports appetite regulation, blood sugar balance, and metabolic function.
Activates GLP-1 receptors
GLP-1 is a hormone your gut produces naturally, lasting only 1-2 minutes in the body. GLP-1 receptor agonists are engineered to activate the same receptors for days instead of minutes, providing sustained appetite regulation and metabolic support.
Supports metabolic health
GLP-1 receptor agonists have been shown in studies to lower blood pressure, improve blood sugar regulation, and reduce lipid levels and inflammatory markers. These effects appear independent of weight loss, driven by direct GLP-1 receptor activation in the heart, blood vessels, and kidneys.
Signals satiety
GLP-1 receptors in the brain suppress hunger and amplify fullness signals. The GLP-1 hormone can also slow digestion, extending a feeling of fullness after meals.
