Mike_Toronto – November 10, 2025

I’ve been using this for 6 weeks to bulk up. The strawberry flavor tastes great, not too sweet. Each serving is huge – exactly what I need post-workout. Mixes well with milk. Noticed good weight gain, but it’s a bit pricey. Worth it for the quality. Way better than watching Canadiens vs Devils, at least I’m getting stronger!
