Frequently Asked Questions

What is whey protein isolate?

Whey protein isolate (WPI) has the highest concentration of protein and BCAAs, while having less carbs, cholesterol, and fat compared to other whey proteins. WPI is also low in lactose and easy on your digestive tract.

What is hydrolyzed whey protein isolate?

Hydrolyzed whey protein isolate (HWPI) is whey protein isolate that has been broken down into smaller chains of amino acids called peptides. Peptides are easier to digest, allowing for faster absorption into the bloodstream.

What are BCAAs?

Branched-chain amino acids (BCAAs) include leucine, isoleucine, and valine. They support muscle growth and reduce muscle fatigue.

You get what you pay for.
I've been taking supplements since I was 16, and I've found out pretty early on you get get what you pay for with supplements. This stuff is awesome! I've recently become lactose intolerant and I thought I couldn't handle protein shakes again, I wanted to stay within the ON brand and didn't want to go through a guess and check with plant based ones when I can't handle non-milk alternatives with coffee. Anyways, this stuff mixes really well with cold water and tastes like a milkshake, tames the hunger and if you're really hungry just do an extra scoop (depending on your personal goal). Best part, my gut and toilet don't hate me when taking it.

SOLID PRODUCT
I've sampled other products (Muscle Tech specifically) before doing the proper research. GS is BY FAR one of the best products on the market. I'm not one of those pansies that judge a product by taste and not quality. The taste is so-so at best. The purity far out ways the mediocre taste. I would CERTAINLY recommned this product..... AGAIN
