R1 protein isolate is my go to for whey protein. No gimmicks or outrageous claims it’s just a clean and quality derived protein powder. The flavors are awesome and it mixes very well. It’s extremely low carbs, low calorie, and at muscle and fitness - extremely great deal!  *

Salted caramel is easily one of the best caramel flavors I’ve tried. Red velvet was a slight let down, but not the worst I’ve had. Great deals nonetheless! *

Rule 1 Protein has never disappointed me. This isolate has everything you need in a protein powder. Low calories, not fat, no sugar, no carbs, high protein. Chocolate peanut butter is my absolute favorite because I love peanut butter and chocolate.*
