I’ve been using this product for a little over a year now, and here’s what I’ve noticed: ✅ What I liked: Easily mixes with water in a shaker cup. Easy on the gut! Not overly sweetened. The chocolate flavor is my fav. I have gained 12lbs of muscle using this as a meal replacement along with a consistent diet and gym regimen. ⚠️ What could be better: If the scoop were easier to find when you first open it. If they could somehow secure it to the lid that would be awesome. Otherwise it’s a treasure hunt. Overall: This product exceeds my expectations. I would recommend it to anyone looking for a meal replacement that easily mixes with water that doesn’t clump, is easy to digest, and tastes great.
