— Common questions
FORTIFY pricing,
answered.
FORTIFY costs $289 per month at Pepti as a vial, or $289 as a pre-filled pepti Pen. That price is all-in — it includes the compounded medication, the licensed physician who reviews your assessment and manages your care, shipping to your door, and unlimited messaging with your care team. Refills are the same price each month; there is no separate membership, consult, or visit fee.
The compounded FORTIFY from an FDA-registered 503A pharmacy, the vial with sterile syringes and alcohol prep pads, cold-chain shipping, the physician review of your assessment, ongoing physician care and dose adjustments, and unlimited messaging. If the physician does not approve you, the medication charge is refunded.
Yes. FORTIFY is prescription-only. At Pepti you complete a free online assessment, a licensed US physician reviews it, and if it is appropriate for you the prescription is sent to a partner pharmacy that compounds it and ships it to you. Compounded FORTIFY is not FDA-approved; it is prepared to a physician's prescription by a state-licensed, FDA-registered pharmacy.
No. Compounded FORTIFY is a cash-pay prescription and is not covered by insurance or Medicare. Most patients can use HSA or FSA funds, since it is a physician-prescribed medication. Pepti does not bill insurance, which is part of why there are no consult or visit fees.
Research-use-only peptides are sold without a prescription, without a physician, and without a pharmacy. They are labeled "not for human use" for a reason: no one is verifying the identity, purity, sterility, or dose of what is in the vial. Pepti's $289 covers a licensed physician, a state-licensed FDA-registered compounding pharmacy, and independent batch testing — potency, sterility and bacterial endotoxin — at a third-party laboratory. You are paying for the medication to be what the label says it is.
No — every medication is its own catalog price however many are in the plan. Adding a second medication to the same plan means one assessment, one physician review and one shipment — each medication keeps its own catalog price. If you want several peptides for less, a pharmacy-compounded blend puts two to four in one vial at one price.
Once per fill. One vial is your monthly supply, and a fresh one ships about every 28 days depending on the dose your physician prescribes, billed at the same $289 each time. It renews until you cancel, and you can cancel anytime from your account. There is no contract and no cancellation fee.
Most peptide clinics price FORTIFY as a medication fee plus an initial consult, a membership or program fee, and follow-up visit fees, and many require in-person visits. Pepti charges one monthly price of $289 that already includes the physician and shipping, with no consult, membership, or visit fees. Some clinics also dispense research-use-only peptides; Pepti dispenses only physician-prescribed, pharmacy-compounded medication.
