Two prices on its own pages
Boston Medical Group prints 3 prices for compounded semaglutide: $190 Online store plan picker, 1 Month, $199 SlimFitRx Costs & Dosing page, “Get started for as little as $199/month*”, footnoted “a complete 12-week program totals $699 ($199/month + telemedicine platform fee)” and $299 SlimFitRx Program Steps page, “Get started for as little as $299/month*”, footnoted “$999 ($299/month + $100 telemedicine platform fee)”. We rank it on $190 because it's the one-month price on the store's plan picker, where an online order starts. The $199 and $299 figures sit on the older SlimFitRx program pages, which also add a telemedicine platform fee the store doesn't charge.
Dose doesn't change the store price: “your cost never changes with dosage. We charge a flat monthly rate based on the GLP-1 medication prescribed”. Each plan's card reads “4 Weeks of Medication”, the same wording on every plan length.

Selecting “Tirzepatide Injection” on the same store page swaps in its own ladder: $239 for one month, $589 for three ($196.33 a month), $1,074 for six and $1,788 for twelve. The flat-at-every-dose promise covers it too.

The last two columns are our arithmetic, not Boston Medical Group's: the plan's charge against the same number of months bought one at a time at Boston Medical Group's month-to-month price. A prepay only saves that much if you stay on the drug for the whole term.
The service, the checks and who should skip Boston Medical Group are in the Boston Medical Group review. To price a plan line by line with any membership and fee added, use the real cost calculator; it reads the same ladder. How the advertised figure compares with every other company's is on the September 2026 Price Gap Index.
