Facts above are what each supplier says about itself, and we have not tested the products ourselves. "Not stated" means we could not find it on the supplier's site.

What it costs per 222 mg

Bottles come in different strengths and counts, so we divide the price by the number of 222 mg units inside. A 444 mg capsule counts as two. Prices were checked in June 2025 and change often, so treat this table as a way to compare, not a quote. BP Life's own pages quote slightly different per-unit figures for its powder, so we worked ours out from the bag weights.

Price per 222 mg unit
ProductSupplierPricePer 222 mg
Powder, 100 g (450 units)BP Life$84.99about $0.19
Powder, 50 g (225 units)BP Life$50.00about $0.22
222 mg capsules, 120 ctBP Life$73.99about $0.62

222 mg capsules, 30 ctSanare Lab$29.99$1.00
444 mg capsules, 30 ctSanare Lab$39.99about $0.67

BP Life is the cheapest per 222 mg at larger sizes. Sanare Lab has the lowest price for a first 30-count bottle. FenbenLab is left out of the table because its price depends on the bottle size and the store lists several, so check the live price for the size you want. Its MegaPacks (from $289 for 360 to 720 capsules) are aimed at long-term buyers. Capsule prices fall with the volume discounts listed above.

How to buy fenbendazole without getting burned

Because this compound is sold for research and not as an approved medicine, quality depends heavily on who you buy from. Five checks help, and none of them take long.

1. Ask for the Certificate of Analysis first

A CoA is a lab report for a specific batch. Look for the lab's name, the test method, the batch number and a purity figure. A good one also covers heavy metals and microbial contamination. If a seller dodges the question, move on.

2. Capsules or powder

Capsules are pre-measured, which is why most people choose them. Powder is cheaper per milligram but needs a scale accurate to a milligram, and it is easy to get wrong. If you are not set up for that, capsules are the safer choice.

3. Know what the strength means

The number is the amount of fenbendazole in each capsule. 444 mg is simply twice 222 mg in one capsule, and 500 mg is sold only by FenbenLab. The price table above puts them all on one scale.

4. Count the shipping

BP Life charges for shipping under $100, while Sanare Lab and FenbenLab ship free. Outside the US, FenbenLab is the only one of the three with local warehouses.

5. Look for outside signals

Third-party testing, a registered facility, reviews on a site the seller doesn't control. None of these prove a product is good, but a seller with all of them has more to lose than one with none.

Ready to order?

Each supplier has its own store. Ask for the certificate for your batch first, then pick the store that fits where you live.

Common questions

Where can I buy fenbendazole online?

We compare three suppliers here: FenbenLab, BP Life and Sanare Lab. All three sell online and publish some form of purity information. Use the table above to pick the one that fits where you live and what you need.

Is fenbendazole legal and approved for humans?

It is approved as a veterinary medicine, for animals such as dogs, cattle and horses. It is not approved by the FDA for any human use, and these suppliers sell it for research purposes. Talk to a doctor about any health question.

What is the difference between 222 mg and 444 mg capsules?

Only the amount per capsule. A 444 mg capsule holds twice as much as a 222 mg capsule, so you need fewer of them for the same total. The 444 mg is usually cheaper per milligram.

Are these products tested by an independent lab?

Each supplier says so, in different ways. Sanare Lab names third-party HPLC and GC-MS testing, and FenbenLab names FT-IR and HPLC with a batch portal. BP Life says pharmaceutical grade but does not name a method. We have not run our own tests, so ask for the certificate for the batch you are buying.

How much does it cost?

From about $0.19 to $1.00 per 222 mg, depending on the supplier, the format and how many you buy. The price table above has the numbers.
