Does semaglutide with B12 cost more than plain compounded semaglutide?
Usually not. Dose-flat programs like NexLife↗ ($165) and Mochi ($178) price formulations identically whether or not B12 is in the vial, and across our index the additive is a formulation choice rather than a price tier. The real questions about B12 formulations are evidentiary and regulatory, not financial: no controlled trial shows added B12 reduces GLP-1 nausea, and the "it's not a copy because of the additive" legal argument is under direct FDA pressure in 2026. Our B12 explainer covers both.

The market this answer lives in, at the 2026-08-09 capture: verified compounded semaglutide runs $133–$348 a month all-in across 20 programs, with the floor at Oak Longevity (dose-flat, no membership); the approved-product benchmark is Wegovy (NovoCare↗) at $349 maintenance, with the oral pill from $149; and any real insurance coverage beats every cash figure named anywhere on this page.
How to use figures like these well: treat any advertised price without a maintenance-dose figure as a starter teaser; fold every mandatory membership into the total before comparing; read prepaid rates as commitments, not monthly prices; and check the capture date, because a GLP-1 price without a date is a rumor. Those four habits, applied consistently, are most of what separates this database from the marketing it indexes — the full basis definition is in the methodology, and the sortable field is in the price database.
The wider board this answer sits on: verified compounded floors of $215 (tirzepatide) and $133 (semaglutide), brand direct channels at $449 and $349 with the oral pill from $149, and insurance — where it exists — beating all of it. Prices here have only fallen for three straight years, which quietly argues for short commitments and periodic re-shopping; the price-history analysis makes that case with dates.
Basis for every figure: all-in monthly price (medication + mandatory fees) at the maintenance dose, captured from provider pages on the dates in the database. Not medical advice.
