Protein shake
Great product. Started seeing results in 3 weeks. Does have a lot of calories. Everything you need to bulk up fast.

The product is tasty. I put fresh strawberries, along with milk and oats. It’s excellent.
The strawberry flavor is the best.

skin breakout+too expensive relative to results
something about gnc products break me out now. back in 2015-2016 timeframe i used wheybolic with great results. tried wheybolic in 2022 and broke out like a teenager. tried gnc serious mass and after 4 days im noticing the same breakout again. this time my diet is much cleaner which clearly point to this product. on the flip side i can feel the results in the sense of the soreness going away but I don’t have the mass gain as i do with serious on mass(which is $20 cheaper and has more nutrients).
