Ozempic vs Compounded Semaglutide — Storage Differences You Need to Know

VialLock vial storage case organized at home

Brand-name Ozempic comes in pre-filled pens. Compounded semaglutide comes in vials requiring reconstitution and a separate syringe. The storage requirements differ — here's what you need to know.

Ozempic Pens

Pre-filled Ozempic pens are refrigerated until first use, then stable at room temperature for 56 days. No reconstitution needed.

Compounded Semaglutide Vials

Compounded semaglutide typically arrives lyophilized or pre-reconstituted. Lyophilized: stable at room temp for weeks, refrigerated for months. Pre-reconstituted: refrigerate immediately, use within 28-30 days.

Why Compounded Users Need a Vial Case

Unlike Ozempic's self-contained pen, compounded semaglutide vials are bare glass — fragile and light-sensitive. A VialLock hard-shell case is essential for safe transport and storage. Shop semaglutide-compatible vial cases.
