Here is a very cool idea for summer: Peanut Butter Banana Builder Protein Ice Cream! This is what you could eat to pack on muscle mass for some serious ‘gainz’ while keeping cool this summer. It’s made with neutral flavor Karbolyn and EFX Sports Vanilla Pure Whey protein. The entire recipe makes about a pint and has around 1,300 calories. So, if you want to split it with your significant other, it would be about 650 calories each. If you want to split it four ways, then it’s about 325 calories… and… well, you get the picture.
