I’ve been using Optimum Nutrition Gold Standard 100% Whey Protein Powder in Strawberry Banana flavor for a while now, and it’s become a staple in my routine. It tastes delicious, as well as mixes easily with water or milk, creating a smooth and creamy shake every time. I’ve noticed continuous improvements in my muscle recovery and for this reason, I started using this protein powder in my post-workout routine. Plus, it’s low in sugar and high in protein, making it an excellent choice for anyone looking to support their fitness goals.
