## Description

Pro Jym Protein Powder - Milk, Whey protein isolates & Micellar Casein | JYM Supplement Science | Natural Chocolate Brownie, 45 Servings

Review: Great Product Line, flavors meh. - I’ve ordered 3 flavors of Jyms protein powder, vanilla, chocolate peanut butter, and chocolate brownie. Loved the vanilla and chocolate peanut butter flavors, tasted great, mixed well with milk or water. I did not love the chocolate brownie flavor, which imo mixed better with water than milk, but still wasn’t very great, won’t order that flavor again, but the others are great.
Review: Great flavor - This brand of protein powder is my favorite for mixing with just water. It has a great flavor. I do occasionally mix it with half almond milk half water so it's creamy but it's definitely not necessary.
