VitaStir review

What it is

VitaStir is a hybrid injection service running physical clinics alongside an online store of at-home injection kits. Its catalog covers NAD⁺ in three forms — an in-clinic subcutaneous injection, an in-clinic infusion, and an at-home NAD⁺ (Active Form) injection kit — plus glutathione and a high-dose GSH kit, vitamin C, MIC B12, B-complex, biotin, NAC, GlyNAC, L-carnitine, vitamin D and a set of branded blend shots, and separately compounded semaglutide and tirzepatide kits. Every home kit is described as a 30-day supply for self-injection.

How it works

Two models under one brand, and which one applies changes everything about the purchase. In-clinic, you book an appointment and a nurse administers the injection or drip — that is a per-visit purchase with no subscription attached, and the site lists clinic locations and an appointment scheduler. At home, you order a kit and it ships only after a VitaStir physician reviews the medical history you submit; the site states that if the physician does not approve for any reason, you will be fully refunded. That refund-on-non-approval structure removes the most common complaint in this category, which is paying for an intake that goes nowhere, and it is stated plainly rather than buried. Three gaps. The states it can serve by telehealth are never published, so home-kit eligibility is a question you resolve by ordering. No compounding pharmacy is named for the injectables. And no dose is stated for the NAD⁺ home kit — the strength that would let you compare it against a $189 or $249 monthly plan elsewhere is simply absent, which matters more here than usual because the whole appeal is price.

Pricing transparency

Transparent per item, and structurally different from a monthly plan in two directions at once. In-clinic NAD⁺ subcutaneous injections are listed at $79; the NAD⁺ infusion is listed without a price. The at-home NAD⁺ (Active Form) injection kit shows a current price of $91 against an original price of $449, and the store carries a site-wide seasonal promotion code on top of that. A 79% discount is not a price you can plan around — the number a reader should hold is the $449 the seller itself calls regular, with $91 as what the promotion currently allows. That is why we publish no floor. Glutathione follows the same shape at $79 against $289, with a high-dose GSH kit at $399. For comparison only, and not as an NAD⁺ price: its compounded GLP-1 kits run $99 to $145 as 30-day supplies. Before ordering, ask two things — the milligrams of NAD⁺ in the kit, and whether the promotional price applies to refills or only to the first order.

Branded vs compounded

Prescription and physician-reviewed, with a licensed provider deciding whether treatment is appropriate; compounded preparations are not FDA-approved and compounded sterile products are not reviewed by the FDA for purity and potency the way approved drugs are. No compounding source is named for any injectable. On the evidence, none of the three NAD⁺ routes VitaStir sells has controlled human outcome trials behind it. Injected NAD⁺ has none; infused NAD⁺ has none either, and the single human intravenous study was a pharmacokinetic pilot which found that infused NAD⁺ clears from plasma quickly — a finding about disposition, not benefit. The NAD⁺ forms with human trial data are the oral precursors nicotinamide riboside and nicotinamide mononucleotide, and what those trials reliably demonstrate is a raised blood NAD⁺ level, a biomarker rather than a clinical outcome. Injectable glutathione has essentially no controlled human outcome data behind the detoxification, immunity and skin-brightening claims made for it. A low price changes what you risk to find out; it does not change the evidence tier. Individual results vary.

Pros and watch-outs

The evidence behind what VitaStir prescribes

We grade the molecules, not the marketing. Here is what the human data actually shows for each thing on their menu.

• NAD+ precursors (NR and NMN): what the human trials actually show

  They raise NAD+ and look safe short-term — but human evidence is surrogate-marker level, and no trial shows they extend healthspan.

• NAD injections: how to get them near you or online, and what the evidence really says

  Subcutaneous NAD+ injections are sold as a cheaper, at-home alternative to the IV drip — via “near me” clinics or telehealth shipped to your door. They’re compounded, not FDA-approved, and have no outcome trials; oral NR/NMN precursors are the route with the human data.

• NAD+ IV therapy: an expensive drip ahead of its evidence

  Clinics sell NAD+ infusions for anti-aging, energy and addiction at $250–$1,500 a session — but there's no controlled trial of IV NAD+, and the real human evidence is for oral precursors, not the drip.

• Glutathione: the master antioxidant, and where the evidence actually is

  Oral glutathione really does raise your body stores (a 6-month RCT proved it) — but the longevity and detox claims are unproven, skin-lightening is modest, and IV glutathione is the most marketed, least evidenced route. The precursors may be the smarter bet.
