Who FenbenLab is
FenbenLab is the broadest of the three suppliers we compare. It sells several capsule strengths, powder in many sizes and large bulk bundles, and it ships worldwide from warehouses in the US, UK, Canada and the EU. If you live outside the United States, it is the obvious one to start with.
It is also the supplier this site first covered. We say that up front, because it affects how you should read our reviews. We still hold it to the same checks as the other two.
What it sells
| Product | Sizes | Notes |
|---|---|---|
| 222 mg capsules | 30, 60, 90, MegaPack | The standard strength |
| 444 mg capsules | 30, 60, MegaPack | Twice the amount per capsule |
| 500 mg capsules | 90, 180 | Only FenbenLab sells this strength |
| Powder | 1 g up to 250 g and more | For buyers who weigh their own |
| MegaPacks | 360 to 720 capsules | Starting around $289 |
Prices depend on size and change with promotions, so we don't quote a table of them. The store lists the current price for each option. The "from" prices we saw were about $41 for a 222 mg bottle and about $59 for a 444 mg bottle, and we could not confirm the capsule count behind each.
The capsules
FenbenLab 222 mg capsules
- Stated purity 99.9% or higher, with each batch tested
- Plant-based HPMC shell and no fillers listed
- Dose accuracy stated as within 2%
This is the one most people start with. The 30-count bottle works as a trial, and the bigger bottles cost less per capsule.
FenbenLab 444 mg capsules
- Same testing and the same plant-based shell
- Priced lower per milligram than the 222 mg
- Also sold in MegaPack sizes
FenbenLab says the 444 mg works out about 15 to 20 percent cheaper per milligram than the 222 mg at the same bottle count, and that the gap widens in the large packs. That is its own figure, and you can check it against the live prices.
FenbenLab 500 mg capsules
- Sold only by FenbenLab
- Bottles of 90 or 180
- Stated dose accuracy within 2%
If you specifically want 500 mg per capsule, there is nowhere else among these three to get it. If you don't have a reason to want it, 222 mg and 444 mg are the sizes everyone else sells, so they are easier to compare.
MegaPacks and powder
MegaPacks are the large bundles, 360 to 720 capsules in one order, and the price per capsule is the lowest FenbenLab offers. They suit buyers who know what they want and would rather order once. A single batch certificate also covers the whole order, which keeps the paperwork simple.
The powder runs from 1 g to bulk quantities of 250 g and over. As with any powder, you need a very accurate scale, and capsules are the better choice for most people.
Testing and the CoA portal
FenbenLab names two methods. Bruker FT-IR spectroscopy confirms the compound is what it should be. HPLC measures how pure it is. Each batch is tested, and results are published through an online Certificate of Analysis portal where you enter your batch number.
That is the most open system of the three suppliers, because you can look up the result for what you actually bought. Two cautions apply. We have not audited the lab results, and FenbenLab does not list certifications such as GMP or an FDA-registered facility the way Sanare Lab does. It also doesn't say whether heavy metals or microbes are tested.
Shipping
Shipping is free worldwide, with stock held in the US, UK, Canada and the EU. For buyers outside the US that matters a lot, since the other two suppliers ship from the United States only.

Our verdict
Good for: buyers outside the US, anyone who wants the 500 mg capsule, bulk buyers, and people who like to look up their own batch results.
Not so good for: buyers who want formal certifications on the page, or who want the lowest price for a first bottle in the US. Sanare Lab is better on both.
If you are in the US and care most about price, BP Life is cheaper per 222 mg, and it has a discount code:
