The device is the price axis
Six products, two molecules, three presentations each. A reader can see immediately what a pen costs over a syringe, and what a vial costs over both. Four sellers on this roster publish a price for both a pen and a vial of the same product — Alloy, Sesame Care, Trust Lab and Slendid — and Slendid is the only one that adds a pre-filled syringe to the comparison.
Each preparation is described as including B12, so what is in it is named rather than left as a generic GLP-1.
The vial costs the most
In most of this market a vial is the cheap option and a pen is the convenience premium. Here the order runs the other way for both drugs: syringes cheapest, then the pen, then the vial.
Nothing on the page explains it. It is worth a second look before assuming the format ladder behaves the way it does elsewhere, and it is exactly the kind of ordering a comparison that averages formats would erase.
No period, and no company
Not one of the six figures carries a billing period. There is no month, no fill interval, no plan term and no dose ladder. Every row here is stored as a non-monthly figure for that reason.
No operating company appears on any page we read. The site says there are no hidden fees and that a patient can cancel at any time, neither of which answers whether a membership fee exists. Its own pricing path returns a 404 with a body large enough that a size check would call it a real page.

See Slendid's current price →Good fit if
- Readers choosing between a syringe, a pen and a vial with the price difference in front of them.
- Buyers who want the added ingredient in the preparation named.
- People who want to see all six of a seller's products priced without an intake.
Look elsewhere if
- Anyone who needs a monthly figure; none of the six carries a period.
- Readers who need to know which company they are buying from.
- Buyers who want a named pharmacy, a named clinician or a service-area list.
- Readers for whom an FDA warning letter is disqualifying.
How this review was verified
- Re-read the priced homepage, the about page and the privacy and terms page on 7 September 2026, comparing requested to effective URLs and running a nonsense path against the host in the same run, which returned a 404.
- Recorded all six figures rather than the lowest, and stored every one as non-monthly because no period appears beside any of them.
- Read the status code rather than the body size on every result, after establishing that this host's own pricing path returns a large 404.
- Ran a widened corporate-suffix pattern across every cached body on the host, proved first against a page known to name a company; it returned nothing here.
- Screened the brand against FDA's live warning-letter datatable with a positive and a negative control in the same invocation, and re-fetched the letter to confirm its title matches the name, reference number and date.
