Is It Legal to Sell Diabetic Test Strips?
Is it legal to sell diabetic test strips? Yes, in most cases — but there's one exception that genuinely matters, and most buyers won't tell you about it because it costs them business.
Legal to sell
- Sealed, unexpired test strips you bought or that came through commercial insurance
- CGM sensors — Dexcom, FreeStyle Libre
- Pump supplies, infusion sets, reservoirs
- Lancets, meters, and related over-the-counter items
Not legal to sell
- Anything paid for by Medicare, Medicaid, or another government program
- Prescription medications — insulin, Ozempic, Mounjaro
- Expired product sold as unexpired
- Recalled lot numbers sold as current stock
Is it illegal to sell diabetic test strips?
Only in specific circumstances. Test strips are an over-the-counter product — you can walk into a pharmacy and buy them without a prescription — and reselling something you legally own is ordinary commerce. Nothing about it is inherently illegal.
What makes a sale illegal is where the supplies came from. If Medicare, Medicaid, or another federal or state health program paid for them in whole or in part, selling them is a federal offense — and a buyer who knowingly purchases them can be liable too. That's a real prosecution risk on both sides, not a technicality.
How to tell if yours were government-funded
Check the box and your pharmacy paperwork. Supplies dispensed through a government program are frequently marked, and packaging printed "Not for retail sale" is the clearest signal. If you paid cash, or used commercial insurance with a normal copay, or bought them off the shelf, you're almost certainly fine. If you're not sure, say so — we'd rather sort it out first than have either of us find out later.
Can you sell diabetic test strips you don't need?
Yes, and having extras is more normal than people assume. Supplies ship in 90-day batches ahead of need. Your doctor moves you from fingersticks to a CGM and the strips keep arriving. Insurance changes and so does your meter. A relative passes and the closet is still full.
None of that is waste on your part — it's just what's left over. And an unopened box has a date on the side. Everything it's worth is on the near side of that date.
Why this question comes up constantly on Reddit
If you searched this with "reddit" on the end, you were looking for someone without a stake in the answer. Reasonable. It's also the single most repeated question in the diabetes communities, and it keeps getting re-asked because two different things get tangled together every time.
The first tangle is "gray market" versus "illegal." Resale of test strips is unregulated in ways that make people uneasy — there's no licensing regime for it, and coverage of the secondary market tends to use words like "underground." Unregulated isn't the same as illegal. Selling something you own that's sold over the counter is ordinary commerce.
The second is where the supplies came from. Someone answers "it's totally legal, I've done it for years" and they're right — about their own retail-purchased boxes. Someone else answers "it's fraud, people go to prison" and they're right too — about Medicare-funded supplies. Both answers are correct and they're answering different questions, which is why the thread never resolves.

What about unused Ozempic, Mounjaro, or insulin?
You can't sell those, and we don't buy them. This is a genuinely different category — not the same gray area as test strips. Those are prescription medications, not over-the-counter devices, and individuals can't legally resell prescription drugs.
It's also unsafe to buy them secondhand, which is why no legitimate business does. The FDA has seized counterfeit Ozempic that was distributed outside the authorized supply chain — including counterfeit needles whose sterility could not be confirmed. Injectables that leave the regulated chain can't be verified by anyone downstream.
If you stopped a GLP-1 and have pens left, ask your pharmacy about a drug take-back program — many accept unused medication for safe disposal. But check the same drawer for test strips, sensors, or pump supplies. People who switch medications almost always have those too, and unlike the pens, those are worth real money and legal to sell.
What we do and don't buy
We screen for all of this before money changes hands, which occasionally means turning down a box. That's the trade — we'd rather lose a sale than take on something neither of us should be handling.
We buy
Sealed, unexpired test strips, CGM sensors, pump supplies, lancets and meters — with 9+ months of dating paying the most.
We don't buy
Government-funded supplies, prescription medications, opened or expired boxes, or recalled lot numbers — we check those.
