Sema (Semaglutide): What It Is, Research Use, Storage and Single Vials

Sema is shorthand for semaglutide, a peptide that acts on the GLP-1 receptor. In medicine it's the ingredient in Ozempic and Wegovy. Our vial is research powder, not a prescription pen.

Why researchers look at it

Sema was the first of the three big names to reach the market, so it's the usual starting point when people compare Sema, Tirz and Reta.

Sizes

Sema comes as a 5mg vial. Compare it with the others on the Sema page.

Storing semaglutide research powder

Unlike a prescription pen, this vial is dry powder. Keep it refrigerated and shielded from light while sealed; after mixing, it stays in the fridge. More in how to store research peptides.

The 5mg Sema vial

Sema is listed as a 5mg vial you can buy singly or several at a time. Free shipping applies to every US address, overseas delivery is $40 flat, and a free 3ml bac water is available as a checkout option.

Not Ozempic, not a prescription

Single Vial Peptides sells semaglutide powder for laboratory research. It is not a medicine for people or pets, and nothing here should be read as dosing advice.
