Top Protein Myths BUSTED!

Myth icon

Whey protein will make me bulky.

Truth checkmark icon

We believe you get out what you put in – which is why our award winning manufacturing facilities only use the highest quality ingredients and strictest quality control when making our products. Your genetics and your strength training program dictate how much muscle you build. Protein* only supports this training.

Myth icon

Whey protein is bad for my health.

Truth checkmark icon

Protein is an important macronutrient that supports muscle recovery and overall health. Whey protein is a food and a common by-product of cheese making. Those with a dairy allergy should consult their primary healthcare provider before consuming.

Myth icon

Whey protein has to be taken post workout.

Truth checkmark icon

Whey protein can be taken anytime throughout the day to help you hit your daily protein requirements, but it may be a good habit to take your shake after training to support muscle recovery.*
