Provider review
Open Water Rx review
The dual agonist is the cheaper of its two molecules — while a promotional code holds.
The regular price is published beside the promotional one, so you can see the ordering flip back.

In one paragraph
The verdict
The pricing here does something almost nothing else does, and it does it with a coupon. Tirzepatide is a more expensive drug to compound than semaglutide, and virtually every seller prices it accordingly — usually thirty to eighty dollars a month higher. Open Water Rx quotes the dual agonist below the single one, which is genuinely the better deal if you want that molecule, and the whole of the reversal is a founder code. The stated regular price is published beside it, which is the honest way to run a promotion: you can see both scenarios and work out what happens when the code stops applying, and what happens is that the ordering returns to normal with a ninety-dollar gap the other way. Anyone choosing the dual agonist here on price should know they are choosing a promotional rate rather than a structural one. The rest of the presentation is better than average in ways that are easy to overlook. The states served are listed. The pharmacy relationship is stated. A certification claim is made with a verifiable seal rather than an unlinked badge. And the footer links the primary trial publications and the FDA's own shortage database instead of paraphrasing them, which lets you check the evidence rather than take a marketing summary of it. None of that answers the dose question, but it is a more checkable page than most.
Microdosing is off-label and unproven — decide with a clinician. Prices are as published by the provider when we last checked; confirm current terms before you buy.
Who it suits, and who it does not
A good fit if
- You want the dual agonist and are happy to buy while the promotional rate applies
- You would rather a seller publish the post-promotion price than hide it
- You want to read the underlying trials rather than a seller's summary of them
Look elsewhere if
- You are budgeting long-term on the cheaper molecule. That ordering is coupon-dependent
- You want semaglutide. Here it is the dearer of the two while the code holds
- You want a figure attached to a milligram. Neither one is
What it actually costs
Price as published
Semaglutide $249/mo and tirzepatide $219/mo, the second conditional on the code FOUNDER against a stated regular price of $339/mo · ★★ that makes the dual agonist the cheaper of the two here, which reverses the ordering nearly every other seller uses — and the reversal exists only while the code applies; at the regular price tirzepatide is $90 dearer than semaglutide rather than $30 cheaper · both figures are published on the homepage before any intake and the site describes the practice as "radical transparency" with "clear pricing before checkout" · no dose sits behind either figure · the company states it is LegitScript-certified and links a seal for verification, states that pharmacy partners are licensed, and lists the states it serves · its own footer links the STEP 1 and SURMOUNT-1 trial publications and the FDA drug shortage database rather than summarizing them, which is unusual for a seller
- Vs median
- $50/mo above the $169 median across the 242 of 373 programs we track that publish a plain monthly rate
- Market
- $59–$1300/mo is the full published spread in our ranking
- Structure
- Standard plan, self-directed low dose
No low-dose product of its own. Starting low means asking for a smaller amount inside a standard plan, at the standard plan's price.
152 of the 373 programs we track price a small dose this way. ★★ The dual agonist is priced BELOW the single agonist, reversing the ordering nearly every other seller uses — and the whole reversal is a promotional code, with the regular price published beside it. Publishing both scenarios is the honest way to run a promotion: a reader can see that the ordering returns to normal, and widens, when the code stops applying. ★ The states served are listed, the pharmacy relationship stated, and the footer links the primary trial publications and the FDA shortage database rather than paraphrasing them, which lets a reader check the evidence instead of a summary of it. No dose sits behind either figure and no low-dose product is offered.

The honest cons
The cheaper molecule is cheaper only while a promotional code applies.
- At the stated regular price the ordering reverses and the gap widens.
- No dose sits behind either figure.

How it compares
Open Water Rx is one of 373 low-dose GLP-1 programs we track, and 242 of them publish a monthly rate you can read before signing up. The ranking lists every published price on one screen, ordered with the companies that pay us first — a mechanism we state there, on the page it applies to.

Intentional GLP-1 microdosing is off-label and unproven — no randomized trial has established that a sub-label dose does anything, and any dose belongs with a clinician who knows your history. If you are going to have that conversation, have it with real numbers.
