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.

Directions

Mix 1 scoop (31g) of Whey Protein Isolate Powder with 6 to 8 fl. oz. of cold water, milk or other beverage. For 30 seconds, stir, shake or blend until dissolved. Suggested Use: For healthy adults, consume enough protein to meet your daily protein requirements with a combination of high protein foods and protein supplements throughout the day as part of a balanced diet and exercise program.

Warning

To maximize freshness and minimize product clumping, store Tightly-closed container in a cool, dry place. Contents sold by weight not volume. Some settling will occur. Serving scoop included, but may settle to the bottom during shipping.

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.

Contains Sucralose Toxin and Soy Estrogen female hormone
Contains Sucralose (a known toxin that causes serious health problems) and soy (known to convert to estrogen when digested giving you dose of female hormone) should be banned.

Packaging terrible but protein very good
The package was unstable and was missing the scoop. I had tried digging to the bottom but turns out there was no scoop and bottle had dents in it. Overall the protein was very good.

After you mix how long does it stay full strength. Can you keep it 24 hours ?
