MISTR at a Glance
How MISTR Works
MISTR is a telehealth platform that handles the entire PrEP process — from prescription to delivery — without requiring an in-person doctor visit. Here's the step-by-step process.
Complete a health questionnaire (5–10 min)
Answer basic health questions online. This is confidential and HIPAA-compliant. You'll create a MISTR profile that you'll use to track everything going forward.
Complete your labs
Choose between an at-home testing kit (mailed to you — finger-prick blood collection, no needles) or an in-person appointment at one of 2,200+ lab locations nationwide (15 minutes or less). Labs test for HIV, hepatitis B, and kidney function.
Video consultation with a licensed physician
Once your lab results come back (typically 2–3 business days), a licensed physician reviews everything and conducts a video consultation. If PrEP is appropriate, they write your prescription.
Medication ships to your door
Your prescription is sent to a partner pharmacy and ships within 24 hours in discreet packaging. Most patients receive their medication in 1–2 business days. Auto-refills ship monthly — you don't need to remember to reorder.
Renewals every 3–4 months
Every quarter, you'll complete follow-up labs (at-home or in-person) and a brief physician check-in. MISTR handles the scheduling and reminders. Between renewals, medication ships automatically every month.
Is It Really Free? Yes, with Context.
MISTR reports that 99% of patients pay $0 out of pocket. Here's how that breaks down.
If you have insurance: MISTR bills your insurance directly. Under the ACA, private insurance must cover PrEP at $0 cost-sharing — medication, labs, and clinical visits. MISTR handles all the paperwork, prior authorizations, and insurance coordination. If your insurer tries to charge a copay, MISTR works with manufacturer copay cards (like Gilead's $7,200/year copay program) to cover it.
If you're uninsured: MISTR enrolls you in patient assistance programs — primarily Gilead Advancing Access for medication (free Descovy or generic TDF/FTC for patients under 500% FPL). MISTR covers the lab work and physician consultations through 340B drug pricing partnerships with federally funded covered entities. This is how they can offer truly $0 PrEP even without insurance.
The bottom line: For the vast majority of users, everything is free — the consultation, the lab work, the STI testing, the medication, and the delivery. The remaining ~1% of cases where costs arise are typically unusual insurance situations that MISTR's team works to resolve.

Who MISTR Is Best For
People without insurance
MISTR's ability to coordinate free PrEP through 340B partnerships and manufacturer PAPs makes it one of the best options for the uninsured — especially after Ready, Set, PrEP ended in July 2025.
Anyone who values privacy
No in-person clinic visits, discreet packaging, no explanation of benefits sent to family. Ideal for people who want PrEP without involving their family doctor or employer insurance.
People in rural areas
If there's no PrEP-prescribing provider near you, MISTR's fully online model with at-home labs removes the geographic barrier entirely.
Anyone who hates insurance paperwork
MISTR handles everything — insurance verification, prior authorizations, copay card enrollment, PAP applications. You just take the pills.
Who MISTR might not be ideal for
If you want injectable PrEP (Apretude or Yeztugo), MISTR currently only provides oral PrEP. You'd need an in-person provider for injections. If you have Medicaid, MISTR does accept it, but you may get more comprehensive care through a local FQHC or health department clinic. And if you need a PrEP prescription today, the 5–10 day setup time may not work — consider an urgent care or local clinic for immediate access.

How MISTR Makes Money (and Why It's Free for You)
This is the question everyone asks — and it's a fair one. If everything is free for patients, how does MISTR sustain itself?
The answer is the 340B Drug Pricing Program. Federal law requires drug manufacturers to sell outpatient medications to eligible "covered entities" — Federally Qualified Health Centers, Ryan White clinics, and certain hospitals — at 25–50% below the average manufacturer price. MISTR partners with these 340B-eligible entities.
When an insured patient fills their PrEP prescription through MISTR's pharmacy network, the pharmacy acquires the drug at the steep 340B discount but receives insurance reimbursement at the normal rate. The difference generates revenue that funds free care for uninsured patients and sustains the platform. For uninsured patients, manufacturer assistance programs (like Gilead Advancing Access) cover the medication cost entirely.
This is the same financial model used by community health centers across the country. It's legal, established, and supported by federal policy. The important thing for you: you never pay anything.
