Cost Plus Drugs Review

Cost Plus Drugs is a pharmacy, not a weight-loss program

The first thing to understand about Mark Cuban's Cost Plus Drugs is what it is not. It is not a telehealth clinic, it does not have doctors who will see you, and it will not write you a prescription. It is a mail-order pharmacy that fills prescriptions other clinicians write. If you already have a prescription from your own US clinician for a drug it carries, it is one of the most transparent places in the country to fill it. If you are starting from zero and need someone to evaluate you and prescribe, Cost Plus Drugs alone will not get you there.

The second thing to understand is what it sells for weight loss, because it is narrower than many people assume. Cost Plus Drugs does not list Ozempic, Wegovy, Zepbound, semaglutide or tirzepatide. The GLP-1 medications on its list are generic liraglutide and generic exenatide, and only liraglutide is a weight-management product.

The pricing formula is the whole point

Most pharmacies treat their margin as a trade secret. Cost Plus Drugs does the opposite and publishes the math on every product: the manufacturer's cost, plus a flat fifteen percent margin, plus a five-dollar pharmacy labor fee, plus shipping. That formula is the company's reason for existing. Mark Cuban Cost Plus Drug Company, now a public benefit corporation, was built to route around the pharmacy-benefit-manager middlemen who quietly inflate drug prices.

The price for each drug and quantity is shown on its own product page, so you can see the drug price before you send a prescription. Shipping is extra: the site lists a separate cold-chain shipping charge per order, and a flat expedited rate for Alaska and Hawaii. Check the current price on the product page before you order, because the manufacturer's cost moves and the price moves with it.

What it carries: generic liraglutide and exenatide

For weight management, the product to know is generic liraglutide, listed as a generic for Saxenda and sold as a box of five 3 mL prefilled pens. Liraglutide is an older GLP-1 than semaglutide or tirzepatide, and it is the same active ingredient as the brand-name Saxenda pen. The catalog also lists generic exenatide pens in 5 mcg and 10 mcg strengths, but exenatide is a type 2 diabetes medication, not a weight-loss drug.

• Generic liraglutide: listed as a generic for Saxenda, five prefilled pens per box
• Generic exenatide: pens in 5 mcg and 10 mcg strengths (a type 2 diabetes medication)
• Not on the list: Ozempic, Wegovy, Zepbound, Mounjaro, and any compounded semaglutide or tirzepatide

If your clinician has prescribed semaglutide or tirzepatide, this pharmacy cannot fill it. A telehealth program that handles prescribing and dispensing together is the more practical route for those drugs.

How people use it: bring your own prescription

Because there is no intake here, the practical workflow is: get evaluated and prescribed somewhere else, then send a new prescription to Cost Plus Drugs to fill at its published price. Orders are fulfilled through its partner HealthDyne. If you have an existing relationship with a primary-care doctor or endocrinologist, they can send the prescription directly.

• Already have a liraglutide prescription? This is a transparent, low-margin way to fill it.
• Need to be prescribed? You will need an outside clinician first.
• Want clinical follow-up and side-effect monitoring? That responsibility sits entirely with your prescriber, not the pharmacy.

Insurance: a short, named list

Cost Plus Drugs is not purely cash-pay anymore. Its FAQ says it currently accepts prescription insurance from a named list of plans, including AffirmedRx, Archimedes, Capital Blue Cross, SmithRx, TrueScripts, VIVIO and WellDyne, plus other select prescription plans. If your plan is not on that list, you pay the published cash price, so compare it against your usual copay.

Trust and oversight: legitimate, but only as a pharmacy

On the trust side, Cost Plus Drugs is on solid ground as a pharmacy. It shows a LegitScript Certified badge, it publishes its pricing formula openly, and it has no FDA warning letters against it.

But oversight here means pharmacy oversight, not medical oversight. There is no clinical team checking in on how the medication is working for you, no dose-titration support, and no one watching for side effects. With a GLP-1 medication, where nausea and dose ramp-up matter, that monitoring has to come from whoever wrote your prescription.

Who should choose it, and who should skip it

Choose Cost Plus Drugs if your clinician has prescribed liraglutide, you want to see exactly how the price is built, and you are comfortable managing the clinical side through your own doctor.

Skip it if you want semaglutide or tirzepatide, in brand or compounded form, because it does not carry them. Skip it too if you need someone to prescribe for you or want ongoing clinical support built into the price. For those needs, a full telehealth platform that handles intake, prescribing, and monitoring will serve you better. You can see how we weigh these trade-offs in our scoring methodology.

Bottom line

Cost Plus Drugs has the most open pricing in the room, but for weight loss it covers a narrow slice of the market: generic liraglutide, filled from a prescription you bring yourself. If that is what your clinician prescribed, it is a transparent place to fill it. If you are after semaglutide or tirzepatide, look elsewhere.
