FAQ:

Q: Is whey protein isolate worth the extra cost?

A: Yes, isolate is worth it; doesn’t mean you wouldn’t do just as well (for general purposes) w/ an isolate/concentrate blend…like ON 100% Gold Standard. If that’s what you’ve been taking, keep taking it, and feel smart!

Q: Does whey protein isolate increases fat?

A: Whey isolate will not increase fat unless you are in a calorie surplus. A surplus is the first step to gaining fat. I take Myfitfuel’s protein shake post-workout and I have been taking it a scoop daily. The post-workout shake works effectively for my muscles and the recovery process works efficiently with the help of the shake.

Q: Should I use whey protein or pure protein?

A: With PURE Protein, you get the best in the nutrients you need without all the stuff you don’t want in your diet. Made with the highest standards in ingredients, PURE Whey Protein is derived from grass fed, free range cows, which are not treated with bovine growth hormones.

Q: What is a substitute for whey protein isolate?

A: Vegan Pea protein. Lactose-free. Hemp. Brown rice. Soy. Egg white. Casein.
