Our assessment
Slendid publishes six prices: semaglutide and tirzepatide offered as prefilled syringes, pens and vials. This makes the advertised device prices easy to compare, but no listing states the supply period or dose covered. The vial has the highest listed price for each medication; confirm quantities and terms before treating the difference as a device premium.
The device is the price axis
The page lists two medications in three presentations each. Compare the device, dose, total quantity and supply period together before deciding which offer costs less.
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
The listed order for both medications is syringes, then pens, then vials from lowest to highest price. Without a supply period and quantity, that is not a reliable comparison of ongoing treatment cost.
Nothing on the page explains why. Take a second look before you assume the format ladder behaves the way it does elsewhere.
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 anywhere on the page.
No operating company is named. The site says there are no hidden fees and that you can cancel at any time, neither of which answers whether a membership fee exists. Its own pricing page doesn't load.

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.
What stands out about Slendid
Strengths
- Prices every delivery device separately on one screen, so the premium for a pen over a syringe is visible rather than buried in an option picker
- States that the preparation includes B12, so what is in the vial is named rather than described as a GLP-1
- Requires no intake to see the full price list
Trade-offs
- Received an FDA warning letter (No. 716700, issued September 2025) over the unlawful sale of unapproved and misbranded drugs online
- No figure carries a billing period, so nothing here can be placed beside a monthly rate without an assumption the seller never makes
- Publishes no legal entity on any page read
- Its own pricing path returns a 404 with an 11,955-byte body, which a size check would read as a real page
- Names no compounding pharmacy, no individual prescribing clinician and no service area
How this review was verified
- The homepage, read, prices all six products. None of the six figures carries a billing period.
- Slendid's own pricing page does not load.
- No operating company is named on any page of the site.
- The FDA issued Slendid a warning letter in September 2025 concerning the unlawful sale of unapproved and misbranded drugs online.

Frequently asked questions
How is it priced?
By delivery device: prefilled syringes, pens and vials each have a listed price for each drug. Confirm the dose, quantity and supply period before comparing them.
Which format is cheapest?
Prefilled syringes have the lowest listed figure for both drugs and vials the highest. The page does not establish whether the quantities and supply periods are equivalent.
Is the price monthly?
The page never says. No billing period, fill interval or plan term appears beside any of the six figures.
Is there a membership fee?
Not stated. The site says there are no hidden fees and that you can cancel any time, which doesn't answer the question.
Does Slendid have an FDA warning letter?
Yes, issued in September 2025, concerning the unlawful sale of unapproved and misbranded drugs online. It is a disclosure worth knowing about before you buy.
Ready to compare directly?
Slendid scores 1.4/10 on this site's rubric. Review the published prices and their conditions above, then confirm your total with the provider. Visiting its site does not commit you to treatment.
