Provider review

VitaStir cost: $145 / kit tirzepatide

Every single product is on sale, and always has been.

VitaStir sells its injectables as one-off kits rather than subscriptions, which is genuinely rare here — you buy a kit, it arrives, nothing renews. Semaglutide is $125 and tirzepatide $145, well under most of the market. Every one of its sixteen products also carries a struck-through higher price, so the discount is the price.

The catch — Every price is a sale price. All sixteen products on the storefront carry a struck-through original — semaglutide marked down from $599, tirzepatide from $399, glutathione from $289 — and there is no sign the higher figures are ever charged. That does not make the low prices false, and they are genuinely low. It does mean the apparent 79% saving on semaglutide is not a saving, and a countdown-free permanent sale is still a permanent sale.

What they advertise

One-off kits rather than monthly plans. Semaglutide $125, tirzepatide $145, NAD+ $91, glutathione $79, B12 $65. Roughly a dozen other injectables — vitamin C, MIC B12, L-carnitine, biotin, vitamin D — run from $75 to $499.

What you actually pay

There is no monthly rate, and that is the point: you pay once for a kit. What you spend over a year depends entirely on how often you reorder, which VitaStir leaves to you rather than deciding for you.

The bottom line

VitaStir is the cheapest way into a compounded GLP-1 on this site, and it gets there with a model almost nobody else uses: you buy a kit outright instead of starting a plan. Semaglutide runs $125, tirzepatide $145, NAD+ $91 and glutathione $79 — one payment, no membership, no auto-renewal, nothing to cancel three months from now when you have forgotten you signed up. If what has kept you off a GLP-1 is the subscription rather than the drug, that is a real difference. The thing to see clearly is the discount: all sixteen products are marked down from a higher figure that nobody appears to pay, so read $125 as the price and $599 as decoration.

VitaStir appears on our tirzepatide provider ranking, our semaglutide provider ranking and our combined weight loss injections ranking. Nothing on this page is a performance claim.

Who it is for, and who it is not

A good fit if

  • You want the lowest entry price for compounded semaglutide — $125 is among the cheapest published anywhere here.
  • You hate subscriptions. These are one-off kits, so there is nothing to cancel and nothing renews.
  • You want more than a GLP-1 from one place: NAD+, glutathione, B12 and a dozen other injectables are all sold the same way.

Look elsewhere if

  • You want ongoing clinical support. This is a kit you buy, not a program you join.
  • You take the struck-through price seriously — every product carries one, so it tells you nothing about value.
  • You want to know which pharmacy compounds it, or which states it ships to. Neither is published.

Who fills your prescription

No category stated

VitaStir does not name the pharmacy that fills your prescription.

What its own site says

No compounding pharmacy is named, and no regulatory facility category is stated anywhere on its storefront.

What's the difference between 503A and 503B?

A 503A pharmacy compounds for one named patient; a 503B outsourcing facility manufactures in batches under CGMP. Neither is a quality guarantee on its own — a named facility is simply a fact you can check, and an unnamed “partner pharmacy network” is not. Compounded peptides are not FDA-approved.

Where you can get it

Not published

No state list is published.

The honest cons

The part they would rather you skipped

Nothing at VitaStir is ever sold at its stated price. All sixteen products carry a struck-through original next to the figure you actually pay — semaglutide down from $599 to $125, tirzepatide from $399 to $145, glutathione from $289 to $79 — and a sale that covers the entire catalog with no end date is just the price list with extra steps. The prices themselves are real and genuinely among the lowest here; it is the implied 79% discount that is not. Beneath that sits a quieter gap: no pharmacy is named, no regulatory category is stated, and no state list is published, so what you are buying cheaply is also the thing you can learn least about.

  • All sixteen products are permanently discounted from a higher price nobody appears to pay.
  • No compounding pharmacy is named and no facility category is stated.
  • No state list is published.
  • Kits are one-off purchases, so there is no ongoing clinical relationship built in.

None of this is unique to VitaStir — the whole category shares it.

How it compares

Read this before you buy

A provider comparison is half the decision. The other half is whether the compound does anything for you at all. The evidence below is where that gets settled.
