Free Worldwide Shipping & Returns

Many companies use shipping and handling fees to increase their profit margins, but here at Legion, we hate profits so our shipping is 100% free!

Okay, we do dig on profits, but we also go in for happy customers, and free shipping works like gangbusters.

So, if you live in the United States, your order ships free regardless of order size, and if you live anywhere else, your order ships free when it’s over $199.

Why the restriction on international orders? Unfortunately, shipping abroad is very expensive, and if we didn’t require a minimum order size, we’d lose a lot of money.

That said, as most international customers spend about $200 with us each time they shop, this setup is a win-win.

And no matter what you decide to buy, you’re always protected by our ironclad, 100% money-back guarantee that works like this:

If you don’t absolutely love our stuff for whatever reason, you get a prompt and courteous refund. No forms to fill out or hoops to jump through.

That means you can say “yes” now and decide later. You really have nothing to lose.

Made in USA

Where your supplements are made matters, because rules and regulations regarding quality and purity differ from country to country.

And if you want to ensure the supplements you’re swallowing every day are safe and effective, you want products produced in the USA.

That’s why all of our supplements are made in America in NSF-certified and FDA-inspected facilities that operate in accordance with the Current Good Manufacturing Practice (cGMP) regulations.

We pay a premium to work with the best manufacturers in the country, but it’s the only way we can also produce the best all-natural sports supplements.

Lab Tested

Did you know that studies have shown that many supplements contain dangerously high levels of toxins like lead, arsenic, and cadmium?

Not ours.

Every ingredient of every supplement we produce is tested for heavy metals, microbes, allergens, and other contaminants to ensure they meet the strict purity standards set by the FDA.

Naturally Sweetened & Flavored

While artificial sweeteners may not be as dangerous as some people claim, studies suggest that regular consumption of these chemicals may indeed be harmful to our health and that more research is needed.

That’s why all of our supplements are naturally sweetened and flavored and contain no artificial food dyes, fillers, or other unnecessary junk.

Science-Backed Ingredients & Doses

Every ingredient in every supplement we offer is backed by peer-reviewed scientific research, and every dose is included at clinically effective levels.

That means everything in our products is based on published scientific studies demonstrating real benefits, not the restrictions of razor-thin production budgets and gluttonous profit margins.

So, while everyone claims to have the best supplements on the market, we can back it up with real science and real numbers.
