Compounded tirzepatide glossary
Plain-language definitions for the pricing, pharmacy and telehealth terms used across this site.
Key terms
Compounded tirzepatide
A tirzepatide preparation made by a licensed pharmacy for an individual prescription. It is not an FDA-approved finished drug product, unlike brand-name Mounjaro and Zepbound.
503A pharmacy
A state-licensed compounding pharmacy that prepares medications for individually identified patients pursuant to a prescription.
503B outsourcing facility
An FDA-registered facility that may compound in larger batches under stricter cGMP standards similar to manufacturers.
Flat-rate pricing
A model where the monthly price is the same across every eligible dose (dose-independent). The price at 2.5 mg equals the price at 15 mg.
Dose-based (dose-tiered) pricing
A model where the monthly price increases as your prescribed dose increases.
Starter dose
The low initial dose (commonly 2.5 mg weekly) at which most patients begin before titrating upward.
Maintenance dose
The ongoing target dose a clinician settles on, often 10–15 mg, where most of treatment occurs.
Titration
The gradual stepping-up of dose over weeks to months as tolerated.
Certificate of analysis (CoA)
A lab document confirming the identity, potency and purity of a compounded batch. Reputable programs provide one on request.
Cash-pay
Paying out of pocket rather than through insurance. Compounded tirzepatide is generally cash-pay, often HSA/FSA-eligible.
HSA / FSA
Health Savings and Flexible Spending Accounts — pre-tax funds often usable for eligible cash-pay medical costs; confirm eligibility.
Telehealth prescribing
Evaluation and prescribing by a clinician licensed in your state via video, phone or compliant asynchronous review.
FDA-approved
A finished drug product the FDA has reviewed and authorized. For tirzepatide, only brand-name Mounjaro and Zepbound (Eli Lilly) are FDA-approved.
Off-label use
Use of a medication for a purpose not in its approved labeling, at a clinician's discretion.
Prior authorization
An insurer's requirement to approve coverage before paying for a medication — relevant mainly to brand-name, not cash-pay compounded.
Drug shortage list
The FDA's official list of drugs in shortage. Compounding of copies is generally permitted only under specific conditions, and shortage status affects those conditions.
Annualized cost
The estimated 12-month total at a typical maintenance dose, including any dose-based increases plus visits, labs and shipping.
