Tyrant

I don't think the strain from the SSJ3 would be enough to make Goku that much weaker. The only time something unrelated to battle had an affect on power levels was when the heart virus attacked Goku. You could noticably see that he is tired and in pain. Goku wasn't shown to be losing any power when he was in SSJ3. People constantly say SSJ3 causes massive amounts of strain etc. I want to know where this comes from. The only type of problem that it created was that it shortened Goku's time on Earth. It was never said to make him weaker.
