The HSA/FSA Playbook for GLP-1 Users
HSA / FSA Resource Center
Your HSA/FSA is a standing discount. Most people never use it.
Pre-tax dollars stretch 30–40% further than post-tax ones, depending on your tax rate. Here is where they work, what they cover, and how to stop leaving money in the account.
Start here: the Habthera store on Flex Marketplace
Flex runs the HSA/FSA checkout for ASP-1. You answer a short questionnaire, a licensed clinician reviews it, and if you qualify you get a Letter of Medical Necessity and an itemized receipt — the two documents every HSA/FSA administrator asks for. About three minutes, and you can pay with an ordinary card and reimburse yourself later.

In order of how much they are usually worth.
A GLP-1 prescribed for a diagnosed condition such as obesity or type 2 diabetes generally qualifies as an eligible medical expense. At roughly $300–$450 a month, this is the single largest eligible expense most GLP-1 users have.
Supplements, nutrition products and a lot of wellness spending become eligible for qualifying customers once a clinician documents why you need them. No letter, no claim. The letter is the whole game.
Unlike an FSA, it rolls over and it invests. Pay small expenses out of pocket, keep the receipts, and reimburse yourself years later — there is no deadline on reimbursement. Meanwhile the balance grows untaxed.
Check your plan year end date, then check whether you have carryover or a grace period. Whatever is left over past that window is gone. This is the deadline people find out about in January.

Avoiding the cheap route that is not legitimate
There is real telehealth and there is grey-market sourcing. The difference matters.
A licensed clinician who evaluates you, a US-licensed pharmacy that dispenses FDA-approved product in its original manufacturer packaging, a real prescription in your name, and an itemized receipt with an NPI on it. Plenty of telehealth platforms meet this bar.
No clinician contact. Product sold by the vial with no prescription. Prices far below the manufacturer numbers above. Payment by wire, crypto or gift card. No itemized receipt — which also means nothing your HSA/FSA administrator will accept.
How a Letter of Medical Necessity works
Usually a short questionnaire. On Flex this happens inside the checkout and takes about three minutes.
It names the condition, the product and the duration. It is yours — the merchant never sees it.
Some administrators ask for both up front, most only if audited. Keep them either way.
ASP-1 is built for the muscle problem GLP-1s create
25 g of total protein from whey isolate and collagen, plus creatine, magnesium and methylated B-12 — formulated by a board-certified physician for people losing weight fast. HSA/FSA eligible for qualifying customers through Flex.
