About Semaglutide
Semaglutide is a GLP-1 receptor agonist studied in metabolic research. It is usually sold as lyophilized powder in 2mg to 30mg vials. Because vial sizes differ so much between vendors, price per mg is the fairest way to compare, and the table above already does that math for you.
What to Check Before You Buy Semaglutide
- Compare price per mg, not the sticker price. A bigger vial is often much cheaper per mg.
- Look for third party COAs (certificates of analysis) that name the vendor and match the batch you receive.
- Use the vendor's coupon code at checkout. Every price on this page already includes it.
- Check shipping costs and free shipping thresholds, which can change which vendor is really cheapest.
- Watch for sales. Many vendors run weekend and holiday sales that stack with our code; we list them on the deals page.
