Common questions
What pack sizes and strengths are available for Semaglutide?
Semaglutide is offered as a 3-vial kit, a single vial, or a 10-vial box. Available strengths: 5 mg, 10 mg, 15 mg, 20 mg, and 30 mg per vial. Every vial in a kit or box is the strength you select. The price per vial for each pack is shown under the price.
How quickly does Semaglutide ship?
Semaglutide in 5 mg, 10 mg, and 30 mg ships the same day when you order Monday to Friday before 3:00 PM Pacific. Orders after the cutoff, on weekends, or on US federal holidays ship the next business day, and never later than 2 business days after the order. The 15 mg and 20 mg strengths are prepared to order and dispatched within 7 business days. Carrier transit then takes up to 3 business days within the contiguous United States. Standard shipping is a $18.99 flat rate and free on orders over $200.
How should Semaglutide be stored?
Lyophilized (freeze-dried) vials tolerate normal shipping at room temperature. On arrival, keep them sealed, dry and away from light: a refrigerator at about 4 °C for the short term, or −20 °C or colder for long-term storage. Let a cold vial reach room temperature before opening it so moisture does not condense on the powder.
How do I work out the concentration after reconstitution?
Concentration in mg/mL equals the vial amount in mg divided by the mL of solvent added. Our free reconstitution calculator also shows the mg held at each 0.1 mL mark.
Is Semaglutide for human use?
No. Semaglutide is sold strictly for laboratory research use. It is not a drug, food, dietary supplement, or cosmetic, has not been evaluated by the FDA, and is not for human or veterinary use. Purchasers must be 21 or older.
