MY NEW GO TO PROTEIN MILK CHOCOLATE

I’ve tried quite a few protein powders, and this one always ends up back in my pantry. It mixes super easily, even with just a spoon, and it doesn’t have that weird artificial taste some others do.

GREAT FOR SENSITIVE STOMACHS

Tastes good and doesn’t upset my stomach, which is a big deal for me. I usually go for the chocolate flavor — not too sweet, and goes well with water or almond milk.

EASY TO STICK WITH

One of the few proteins I can actually take consistently. No bloating, no weird side effects, and it helps me hit my protein goals without having to force it down.

GOOD TASTE

Been using this after workouts for about six months. Recovery has improved, and I don’t feel as sore the next day. It’s not a miracle, but it definitely helps.

Good balance of taste, mixability, and price. I’ve used more expensive brands and cheaper ones, but this one feels like the right middle ground. You get what you pay for.

FAVORITE FLAVOR SO FAR

Double Rich Chocolate is my go-to. Tastes like a light chocolate shake, especially with milk. Doesn’t feel heavy at all, even right after a tough workout.

WORKS FOR LACTOSE SENSITIVE PEOPLE

I’m lactose sensitive, but this one works fine for me. I think it’s because it uses whey isolate mainly. No issues so far, and I’ve been through a few tubs already.
