What it is
Semaglutide is a GLP-1 medication: it mimics a gut hormone that signals fullness. In large clinical trials, people using semaglutide with lifestyle changes lost about 15% of their body weight over 68 weeks on average. Ours is compounded with B12.
How it works in the body
It slows how fast your stomach empties and acts on appetite centers in the brain, so you feel full sooner and think about food less. It also helps regulate blood sugar after meals.
What to expect
Weeks 1–4: Low starting dose while your body adjusts. Appetite often drops first.
Months 2–4: Your provider steps the dose up. Weight loss usually becomes steady.
Months 6+: Most of the loss in trials happened in the first year.

Common questions
Is compounded semaglutide the same as Ozempic or Wegovy?
It contains the same active ingredient, made by a licensed compounding pharmacy. Compounded medications are not FDA-approved and are not the brand-name products.
How much will I lose?
It varies. Trial averages were around 15% of body weight over about 16 months, alongside diet and activity changes. Some people lose more, some less.
