Pepti

Shoppers who want to see the price of every dose step before they start, with no membership fee on top.

Reasons to consider it

Every dose has its own published price: semaglutide runs $99 to $199 and tirzepatide $159 to $319
No membership fee; the medication price includes physician review, dose adjustments and free shipping
Names a reviewing physician and a dispensing pharmacy, Olympia Pharmacy

What to weigh up

The price rises as your dose goes up, so the $99 starting figure covers only the first step of semaglutide
It bills every 28 days rather than monthly, which adds up to 13 charges a year
You pay at checkout before a provider reviews your intake; you're refunded if you're declined

Compounded drugs are not FDA-approved. Understand the medication options.

Oak

Shoppers who want one price at every dose, no subscription, and the option of a brand-name pen or the Wegovy pill on the same account.

Reasons to consider it

One price at every dose on its order form — $250 a month for semaglutide, $300 for tirzepatide — so titrating up does not raise the bill
The order form shows every price before it asks for your name or any health details
Billed one month at a time with no subscription; a three-month supply paid upfront brings the monthly cost to $200 and about $267

What to weigh up

The homepage advertises weight-loss treatment "from $89/mo" and the weight-loss page "$190/mo", with no term on either and neither matching any price on the order form
The lower price shown first on the order form is a first-month discount; the standing price is the struck-through figure beside it
A three-month supply is billed upfront in one charge, and nothing is refundable once a provider has approved the order and it has shipped
