Gatlan review

What it is

Gatlan is a telehealth platform offering testosterone replacement, medical weight loss with compounded incretin medications, hair restoration, a glutathione line, a tadalafil-and-citrulline performance product and a Longevity Protocol built on rapamycin and NAD⁺. Its homepage separately lists NAD⁺ injections among the therapies available through a Gatlan provider. Clinical leadership is disclosed by name — Dr. Robert Lufkin, described as a professor at UCLA/USC School of Medicine — which is uncommon enough in this category to be the main reason the provider is worth a look. Consultations are free and the process is fully online, with blood panels described as part of the assessment where a provider decides they are needed.

How it works

A free consultation first, then an intake reviewed by a licensed provider who decides whether labs are needed and whether treatment is appropriate, then discreet delivery with ongoing provider contact. Putting the consultation before the purchase, at no cost, is the right order of operations, and building diagnostics into the assessment rather than treating them as an upsell is a genuine point in its favour for a longevity protocol. The disclosure picture around that is thinner than the clinical one. No compounding pharmacy is named and no 503A or 503B designation is given, no LegitScript or other third-party certification is displayed, no corporate legal entity or physical address is published, and no refund or cancellation policy appears on the public pages. The state position is unusually good by comparison: 44 jurisdictions are enumerated outright, with Alaska, Arkansas, Massachusetts, New Mexico, Oregon, Rhode Island and South Carolina excluded, so you can confirm your own eligibility before spending time on an intake.

Pricing transparency

Gatlan's record described pricing as fully gated behind the sign-up flow. That is no longer true — its products page now publishes a starting figure for every category, and the correction matters, because it changes the provider from unpriceable to partly priceable. Testosterone replacement is listed as low as $79 a month, medical weight loss from $199, hair restoration from $49, the pre-workout product from $79, glutathione from $39, and the Longevity Protocol from $99. What there is still no figure for is NAD⁺ on its own. The $99 buys a protocol described as rapamycin and NAD⁺ together, so we have not treated it as an NAD⁺ price and it should not be compared against one. Before enrolling, ask what the NAD⁺ component costs separately, what dose and route it supplies, whether rapamycin is optional or mandatory within the protocol, and what the ongoing rate is once any introductory period ends — none of which is published.

Branded vs compounded

Compounded; not FDA-approved. Prescription required only if a licensed provider finds it appropriate. Gatlan names no compounding pharmacy, gives no 503A or 503B designation, and publishes no compounded-medication disclaimer of its own, so the statement above is ours rather than the platform's — compounded sterile products are not reviewed by the FDA for purity and potency the way approved drugs are. On the evidence, the Longevity Protocol pairs two things that should not be evaluated together. Rapamycin has a substantial mechanistic and animal-model literature and an immunosuppressive side-effect profile that requires real clinical oversight; it is not approved for longevity use in humans. Injected NAD⁺ has no controlled human outcome trials at all — the single human intravenous study was a pharmacokinetic pilot that found infused NAD⁺ clears from plasma quickly — and the NAD⁺ forms with human data are the oral precursors NR and NMN, which reliably raise blood NAD⁺, a raised biomarker rather than a demonstrated benefit. Glutathione, sold here separately, has essentially no controlled human outcome evidence. Individual results vary.

Pros and watch-outs

The evidence behind what Gatlan 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.

• 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.

• TRT: what testosterone therapy is actually proven to do

  An FDA-approved therapy for diagnosed hypogonadism — with real but moderate benefits (sexual function, mood; not vitality), cardiovascular non-inferiority in TRAVERSE, and a real fertility trade-off.
