Semaglutide is currently in stock at 10 shops, all of which have third-party lab tests on file. Prices range from $24.99 to $300.00 per vial, with a median of $7.52 per mg. Vial sizes range from 2mg to 20mg. Last updated 11 September 2026.
117 shops are known to sell Semaglutide — 14 with a live listing, 103 evidenced by a lab test in the last year. 29 listings are identified, of which 20 can be compared per milligram.
Bigger vials cost less per milligram. The vial, freeze-drying, labelling, lab test and shipping cost roughly the same whether it holds 5mg or 100mg, so per-milligram price falls as fill size rises. Compare within your size band rather than across the whole list.
