The full protocol

Everything between your goal and your front door.

MostFit Labs is a telehealth coordination platform. Independent licensed clinicians review your intake and, if clinically appropriate, write a prescription that's filled and shipped by a partner pharmacy in the United States. This page walks through every step so you can review how it works on your own time.

What's in the box.

The package, opened.

No mystery. Here is exactly what arrives, in the order you will see it when you open the mailer.

Outer
Insulated mailer
Plain brown box, no logos, no medication words on the outside. Inside is a foil-lined cooler with frozen gel packs for any refrigerated item.
Vial
Pharmacy-labeled vial
Your name, your prescribing clinician, the medication, strength, lot number, fill date, and Beyond-Use Date are printed on the label. Tamper-evident seal on top.
Supplies
Syringes and alcohol pads
If you ordered an injectable, the box includes the matching syringes, needles, and alcohol prep pads. Sharps disposal instructions are inside the kit.
Paperwork
Patient leaflet and lot card
Plain language directions, side effects to watch for, who to call, and a lot card you can scan to pull up the COA for your specific batch.
How you actually get it.

From the form to your fridge, step by step.

Every order follows the same five steps. Nothing is skipped. There is no version of this where a vial ships without a prescription.

One
You complete the intake
An online form covering your goals, your health history, current medications, allergies, and a few photos and measurements where they are clinically useful. Takes about eight minutes.
Two
A licensed clinician reviews it
A nurse practitioner, physician assistant, or physician licensed in your state reviews everything. They may message you with follow-up questions. If a medication is not appropriate, they will tell you why and suggest an alternative.
Three
They write a prescription
If it's a fit, the clinician writes a prescription with your name, the medication, the dose, and the duration. The prescription is electronically routed to a partner pharmacy licensed in your state.
Four
The pharmacy fills and ships
The pharmacist verifies the prescription, compounds or pulls the medication, runs the required tests, prints your label, packs it cold-chain, and hands it to a tracked overnight or two-day carrier.
Five
You get a tracking link, then the box
Tracking lands in your inbox the second the label prints. The box arrives. If anything is wrong, you have 24 hours to email a photo and we replace it. Your clinician follows up at the four week mark.
The people behind your prescription.

Independent, licensed, inspected.

We do not own the pharmacy that fills your prescription. The medication is dispensed by an independent compounding pharmacy that holds an active license with your state board of pharmacy and is inspected on a regular cycle.

Standards
USP 795, 797, 800
Our partners follow the U.S. Pharmacopeia chapters that govern non-sterile, sterile, and hazardous compounding. Translation: gowning, hoods, air pressure, surface testing, training records, all of it.
Sourcing
FDA-registered ingredients
The active ingredient in your medication is sourced from a manufacturer registered with the FDA, with a Certificate of Analysis on every shipment that arrives at the pharmacy.
Oversight
State board inspections
Your state board of pharmacy can audit any time. The pharmacy keeps every prescription, every compounding record, and every test result on file for years.
Pharmacist
A real person verifies
A licensed pharmacist reviews each prescription before it leaves the lab. Their license number is on the label. You can call the pharmacy directly with a question; the number is on the label too.
What the partner pharmacy tests for.

Five tests, every batch, before anything ships.

Compounded medications are tested per batch (called a lot) by the dispensing pharmacy. Each test below runs before the lot is released. Results travel with the lot and are available to you through the partner pharmacy on request.

Potency (HPLC)
Confirms how much active ingredient is in the vial. Target: within 90 to 110 percent of the labeled strength.
Goal ≥ 99% purity
Sterility (USP 71)
Required for any injectable. Verifies the preparation is free of viable bacteria, yeast, and mold.
Pass or fail
Endotoxin (LAL)
Detects bacterial cell wall fragments that can cause fever even after sterilization.
Below USP limit
Particulate
Visual and instrumental check for visible specks, fibers, or precipitate in solution.
Pass or fail
Container closure
Confirms the vial seal is intact and the rubber stopper has not been compromised.
Pass or fail
Cold chain and storage.

2 to 8 degrees Celsius, end to end.

Refrigerated medications stay refrigerated from the moment the pharmacist seals the box until you put it in your fridge. Ice packs are sized to the season and the route.

Outbound
Insulated mailer with gel packs
Foil-lined cooler, frozen gel packs sized for the route, sealed with tamper-evident tape. Most boxes hold temperature for 48 to 72 hours.
Carrier
Tracked overnight or two-day
UPS or FedEx with cold-chain handling. We do not use ground shipping for refrigerated items. Tracking is shared the moment the label prints.
On arrival
What to do when it lands
Open within an hour of delivery. Move the vial to the fridge. The gel pack should still feel cold. If it does not, take a photo and email support.
At home
Storage at 2 to 8 °C
Refrigerator door is fine. Do not freeze. Use within the BUD on the label, not the lot date. The leaflet inside the box repeats this in plain language.
Straight answers.

The questions serious people ask before they commit.

Everything below is a real question support has fielded. If yours is not here, write to us; we will add it.

Getting started.
Safety and quality.
Shipping and storage.
Privacy and support.
Quick word check.

Plain definitions for the words you'll see.

If a term on this site or on a partner pharmacy label is not in here, email support; we will add it.

503A pharmacy
A state-licensed compounding pharmacy that prepares medications for individual patients with a prescription.
API
Active Pharmaceutical Ingredient. The actual molecule that does the work. The partner pharmacy network sources APIs from FDA-registered manufacturers.
BUD
Beyond-Use Date. The day a compounded preparation should not be used past. Printed on every label.
cGMP
Current Good Manufacturing Practice. The federal standards a manufacturing facility follows for cleanliness, documentation, and quality control.
COA
Certificate of Analysis. The lab report showing the lot passed potency, sterility, and endotoxin testing.
Cold chain
Unbroken refrigeration from the partner pharmacy to your front door. The pharmacy ships in insulated mailers with gel packs that stay 2 to 8 degrees Celsius.
Compounding
The practice of a licensed pharmacist preparing a medication for a specific patient, often at a strength or formulation that is not commercially available.
Endotoxin
A bacterial cell wall fragment that can cause fever even after sterilization. Tested with a Limulus Amebocyte Lysate (LAL) assay.
HIPAA
The federal law that protects your health information. Everything you send us is HIPAA-protected.
HPLC
High-Performance Liquid Chromatography. The standard lab technique for measuring how pure a compound is.
IM
Intramuscular injection. A shot into the muscle, usually the upper outer thigh or shoulder.
Lot
A specific batch of medication made together on a single day under a single set of conditions. Every lot has its own COA.
Lyophilized
Freeze-dried. A common way to ship peptides so they stay stable; you reconstitute with bacteriostatic water before use.
SQ

USP <795> / <797> / <800>
The U.S. Pharmacopeia chapters that describe how compounding pharmacies must prepare non-sterile, sterile, and hazardous medications.

Still have a question? Ask the person who would have to answer it anyway.

Support is staffed by people who can route you to the clinician who reviewed your intake or the pharmacist who filled your prescription. Not a chat bot. Not a tier-one script reader.

The information on this page is for general education and is not a substitute for advice from a licensed clinician. Compounded medications are not FDA-approved drug products. Prescriptions are written only after a clinical evaluation by a U.S. licensed clinician and only when clinically appropriate. State availability varies; the eligible states for each product are listed on its detail page.
