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 every penny of your money back. Holy moo cows. And that means you can say "yes" now and decide later.

Legion Whey Concentrate Ingredients (30 grams per serving)

Avonlac 282® Whey Protein Concentrate Powder (20 grams per serving)

Whey protein concentrate is a form of whey protein made from fresh dairy whey, which is the liquid part of milk remaining after cheese has been made. It undergoes special filtration to remove excess fat and lactose while preserving the protein content and quality.

Avonlac 282® is a premium form of whey protein concentrate made with milk from cows never treated with rBST (a synthetic hormone used to boost milk production) and specifically processed to taste pleasant and dissolve quickly and easily in liquids.

Research shows that supplementation with whey protein concentrate . . .

  • Boosts muscle growth and strength gain when combined with resistance training[7][8][9]
  • May improve recovery after exercise[10]
  • Supports muscle retention while dieting[11]
  • May aid weight loss[12][13]

There’s no clinically effective dose of whey protein concentrate. Instead, use it to help reach the recommended intake of ~0.8 grams of protein per pound of body weight per day.

Grass-Fed Whey Protein Isolate (22 grams per serving)

Naturally Sweetened and 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.[14][15][16][17][18][19]

That’s why we use the natural sweetener stevia instead. Research shows that this ingredient is not only safe but can also confer several health benefits, including better nutrient absorption, healthy cholesterol and inflammation levels, and more.[20][21][22][23]

No Artificial Food Dyes or Other Chemical Junk

No Artificial Food Dyes, Fillers, or Other Unnecessary Junk

As with artificial sweeteners, studies show that artificial food dyes and fillers can cause negative effects in some people, including gastrointestinal toxicity and behavioral disorders.[24][25][26][27][28]

That’s why we use natural coloring and flavoring derived from fruits and other foods as well as naturally derived ingredients for improving texture, enhancing shelf life, and facilitating the manufacturing process.

No Artificial Food Dyes or Other Chemical Junk
