Reviewed mechanism
Semaglutide 15mg — the largest single vial for extended GLP-1 weight loss protocols. Covers 6–12 weeks of supply at maintenance doses and is the most cost-efficient per-mg option.
Best Per-Mg Value
Most cost-efficient semaglutide option — ideal for those planning extended 16–24 week protocols.
Extended Coverage
6–15 weeks at typical doses — eliminating frequent reorders during critical protocol phases.
Same Quality
Identical pharmaceutical-grade purity as smaller vials — Apollo COA per batch.
Semaglutide (GLP-1 S) 15mg: Extended Protocol Guide
Mechanism · Evidence · Application
The Semaglutide 15mg vial is the largest single-vial option — designed for those running extended 16–24 week protocols at maintenance doses. At 1.7–2.4mg per week, a single 15mg vial provides approximately 6–8 weeks of continuous supply.
Optimal for Long-Duration Research
The full clinical efficacy of semaglutide emerges gradually over time. The STEP trials showed that weight loss continued to accumulate through 68 weeks, with the most dramatic improvements in cardiometabolic markers typically observed after 16+ weeks of consistent dosing. The 15mg vial minimizes the logistics of mid-protocol reordering for those committed to full-duration protocols.
Cost Efficiency
At $159.99 for 15mg, the 15mg vial offers the best per-mg price point of all three semaglutide options — approximately $10.67/mg vs. $11.11/mg for the 10mg vial. For those planning extended protocols, this represents meaningful cost savings over multiple purchase cycles.
