Rated 4 out of 5

FitnessEnthusiast92 – November 10, 2025

I’ve been using this weight gainer for two months now, and it’s been a solid addition to my routine. The chocolate peanut butter flavor tastes great and mixes well with milk. Each serving provides good value with 1,250 calories and 50g of protein. While the powder does clump slightly, it’s manageable. My only gripe is the price, but for the quality and results, it’s worth it. Definitely helps with muscle building goals.
