TL;DR
What is MISTR?
MISTR is a telehealth service dedicated to sexual health for men who have sex with men (MSM) and other populations at risk for HIV. Founded to address persistent gaps in PrEP access, MISTR operates in all 50 states and serves patients regardless of insurance status.
The service offers:
- Free PrEP consultations with licensed providers
- At-home or local lab collection (HIV test, kidney function, STI screening)
- Free PrEP medication delivered to your home
- Quarterly follow-up labs and medication refills
- STI testing and treatment
- PEP (post-exposure prophylaxis) for recent HIV exposure
- Coordination of injectable PrEP (Apretude, Yeztugo)
The company's structure is aligned with the 340B Drug Pricing Program — a federal program that requires drug manufacturers to sell medications to eligible safety-net providers at deep discounts. MISTR partners with federally qualified health centers (FQHCs) and Ryan White clinics that qualify as 340B-covered entities.
Why MISTR is actually free (the mechanism)
Skepticism about "free" healthcare is warranted. The key to understanding MISTR's pricing is understanding the 340B program.
The 340B Drug Pricing Program requires pharmaceutical manufacturers to sell drugs to qualified safety-net providers (like FQHCs and Ryan White clinics) at 25–50% below average manufacturer price. This creates a financial spread between the discounted 340B purchase price and the insurance reimbursement when the medication is dispensed.
For patients with insurance: MISTR's partner clinic bills your insurance the standard rate. The spread between the 340B price and the insurance payment covers your consultation, labs, and medication. You pay nothing.
For patients without insurance: 340B pricing combines with Gilead Advancing Access (for Descovy) and generic pricing (for TDF/FTC) to cover the cost. You still pay nothing.
This is why MISTR doesn't charge you — the platform profits from the insurance and 340B economics, not from direct patient payment. It's a structural feature of federal law, not a promotional gimmick.
Who qualifies for MISTR
MISTR serves most adults at risk for HIV:
- At least 18 years old (some states allow younger with consent)
- HIV-negative (confirmed through lab work)
- Resident of the United States
- Potential HIV exposure through sex or injection drug use
- No significant kidney disease (PrEP has specific requirements)
You do not need:
- Insurance (MISTR serves insured and uninsured equally)
- A Social Security Number
- A primary care physician
- Any specific income level
- To document any specific sexual behavior
Step-by-step: how to sign up for MISTR
Step 1: Create your account (~3 minutes)
Go to heymistr.com and create an account. No referral code is required. You'll need a valid email address and a phone number. Your account is private and HIPAA-compliant.
Step 2: Complete the medical intake (~10 minutes)
The intake form asks about:
- Basic demographic information
- Medical history (especially kidney function, hepatitis status, any chronic conditions)
- Current medications (important for drug interactions)
- Sexual health history and risk factors (to determine PrEP appropriateness)
- Insurance information (if you have any — otherwise, you'll indicate uninsured)
- Preferred delivery address
Answer honestly. The intake is confidential, and accurate answers help the provider determine which PrEP option is right for you and whether any special considerations apply.
Step 3: Complete lab work (3–5 days)
Before starting PrEP, you need baseline labs:
- HIV test — PrEP requires you to be HIV-negative
- Kidney function (creatinine) — some PrEP medications require dose adjustment for kidney issues
- Hepatitis B surface antigen — TDF/FTC is active against hepatitis B, so stopping PrEP if you have hepatitis B requires medical monitoring
- Hepatitis C screening (often included)
- STI screening (chlamydia, gonorrhea, syphilis) — routine with PrEP care
MISTR offers two lab options:
- At-home self-collection kit — shipped to your address overnight. You collect samples (fingerstick blood for HIV, swabs or urine for STIs) and ship back in prepaid packaging. Results in 3–5 days.
- Local lab visit — MISTR sends a lab order to a partnered Quest or LabCorp location. You visit for a 10-minute blood draw. Results typically in 24–48 hours.
Either option works for most patients. At-home is more convenient; local lab is faster.
Step 4: Provider review and prescription (24–48 hours)
A licensed provider reviews your intake, labs, and medical history. If PrEP is appropriate, they write a prescription. If anything requires clarification (unusual lab values, potential drug interactions, clinical questions), the provider will message you or schedule a brief video consultation.
For most healthy adults, PrEP is straightforward and the provider simply approves your prescription.
Step 5: Medication delivery (3–7 days)
Your PrEP medication ships to your home in discreet packaging. The packaging doesn't identify the contents on the exterior. Shipping is typically 3–5 business days via USPS or UPS ground (or faster with expedited shipping options).
Step 6: Ongoing care (every 3 months)
Every 3 months, you'll complete follow-up labs (HIV test, kidney function, STI screening) to confirm continued PrEP appropriateness. MISTR coordinates these automatically — they'll email or text you when it's time to complete your next lab collection. Medication refills ship in 90-day supplies.
What MISTR covers vs what they don't
MISTR covers:
- PrEP consultation and ongoing provider care
- All required PrEP labs (baseline and quarterly)
- Oral PrEP medication (generic TDF/FTC or Descovy) delivered to your home
- STI screening and routine treatment
- PEP (post-exposure prophylaxis) for recent HIV exposure
- Injectable PrEP coordination (Apretude, Yeztugo) — including patient assistance enrollment
- Prior authorization handling for insured patients
MISTR doesn't cover:
- Injection administration for injectable PrEP — you'll need to visit a local clinic
- Comprehensive primary care (MISTR is focused on sexual health)
- Specialty HIV treatment (for HIV-positive patients — different providers)
- Mental health services
- Non-PrEP/STI medication prescriptions
MISTR is specifically a sexual health platform. For comprehensive primary care, you'll still want a PCP.
Privacy and discretion
MISTR takes privacy seriously. Specifically:
- Discreet packaging. Medications arrive in plain boxes with no indication of contents.
- HIPAA-compliant messaging. All communications with providers happen through the secure platform, not standard email or SMS.
- Insurance privacy. If you're on a parent's or partner's insurance and concerned about EOB visibility, MISTR offers cash-pay pathways that avoid insurance billing entirely. Talk to support during signup if this applies to you.
- No marketing communications to physical addresses that could reveal you're using sexual health services.
What if I'm on my parent's insurance?
This is one of the most common concerns. If you're under 26 and on a parent's insurance, MISTR can typically handle this privately by using cash-pay pathways that avoid generating insurance EOBs. Ask about this during signup. Alternatively, if your state has minor consent laws for PrEP, you may be able to use your own confidential insurance information.
Injectable PrEP through MISTR
MISTR can prescribe and coordinate injectable PrEP (Apretude or Yeztugo), but with one practical note: the actual injection must be administered by a healthcare provider, so you'll need to visit a local clinic. MISTR handles:
- The PrEP consultation to determine if injectable is right for you
- Prior authorization for your insurance
- Manufacturer patient assistance enrollment if you're uninsured
- Coordinating with a local injection provider (often an FQHC or Ryan White clinic)
- Quarterly follow-up care between injections
For many patients, this hybrid approach — online coordination plus local injection visits — is the most practical way to access injectable PrEP.
Frequently asked questions
Is MISTR really free?
Yes, for most patients — including consultation, labs, and medication. The financial mechanism is 340B pricing combined with insurance reimbursement (for insured patients) or manufacturer patient assistance (for uninsured patients). The platform profits from those arrangements, not from charging you.
How long does MISTR take to ship PrEP?
From account creation to first medication delivery is typically 3–7 days. Most of that time is the lab work and provider review. Shipping itself is 3–5 business days once the prescription is approved.
Does MISTR work in all 50 states?
Yes. MISTR operates in all 50 states and Washington, DC. Service specifics may vary slightly by state based on state-level telehealth and prescription rules, but coverage is nationwide.
Can I use MISTR if I'm uninsured?
Yes. MISTR serves uninsured patients at $0 using 340B pricing combined with manufacturer patient assistance programs. No income verification is required for most patients — the platform handles the 340B mechanics on the back end.
Does MISTR pay FreePrEP.org?
No. FreePrEP.org has no paid relationship with MISTR or any other PrEP provider right now, and no provider can pay to change our rankings. If we ever run a sponsored placement, it will be clearly labeled. Read our editorial policy.
Can I get injectable PrEP (Apretude, Yeztugo) through MISTR?
Yes, with logistics. MISTR can prescribe injectable PrEP, coordinate patient assistance, and connect you with a local injection provider. The actual injection must be administered at a healthcare facility (since it must be done by a provider). MISTR's role is the prescription, coordination, and follow-up care.
Is MISTR safe?
MISTR uses licensed providers, FDA-approved medications, and HIPAA-compliant systems. The clinical care follows CDC and USPSTF guidelines for PrEP. As with any medical service, your comfort with telehealth vs in-person care is a personal decision — but MISTR's clinical standards are comparable to in-person PrEP care.
What if MISTR isn't right for me?
Alternative telehealth platforms include Nurx, PlushCare, Folx (for LGBTQ+ populations), and Q Care Plus. In-person options include your primary care physician, Ryan White clinics, federally qualified health centers, and Planned Parenthood.
