Which Product Is Right For You?

I want to . . .

Not sure? Take the quiz.

Our secret? We spend more on our products. A lot more.

No cheap fillers. No cut-rate ingredients. No itty-bitty doses. This is Legion.

Cost to Produce
Cost to Produce

Sports nutrition companies are notorious money-grubbers. Their favorite way to cut costs is to use cheap ingredients and tiny doses, which is why their products are typically marked up 6-to-12 times.

That means instead of mostly paying for high-quality formulations that work, you’re mainly selling out for dodgy marketing gimmicks, giant retail margins, bloated sales commissions, and hefty wholesaler’s profits.

Legion is different. We cut out the middlemen and shenanigans so we can spend more on what really matters: making superior products with all-natural and clinically effective ingredients and dosages.

Supplement Companies Are Greedy

Supplement companies are notorious money-grubbers. Dishonesty, misdirection, and pseudoscience have been the standard. Until now.

Backed by our "No Return Necessary" money-back guarantee.

No return necessary seal

If you don’t like something of ours, guess what happens next?

No, we don’t request you deliver it to a PO box in the Gobi Desert by carrier pigeon. Nor do we ask you to fill a cursed inkwell with orc’s blood and demon saliva and then use it to complete reams of return forms written in ancient Cyrillic script.

We just . . . wait for it . . . give you your money back. Holy moo cows. And that means you can say "yes" now and decide later.

    "Many supplement companies claim they're ‘evidence-based’ and try to impress you by throwing a few scientific references on their product pages. Legion is science-based at its core. Not only do they dose all of their products based on the clinical doses proven to be effective by scientific studies, they go above and beyond the their competitors by funding new research. They don't just want to sell you supplements--they want to change the supplement industry for the better."
