Weight Gainers: Serious Mass or Mutant Mass, which is better?
Im a really skinny guy, i find it hard to put on weight, I dont have any time to eat properly (summer heres here so maybe now i do), but I definatly need some thing else to put on the weight.
Have you ever used any of these? Which is better Serious Mass or Mutant Mass?
