if your just taking it as is... which is stupid... Just keep it at 50mg, if you jump up to 100 your going to kill your production levels even faster than what your doing... You wouldnt see any benefit in it...
if you were running some test with it... oh for sure. You would see some amazing gains. But... every person is different, there is no "just" answer. But studies have shown an increase compared at 100 instead of 50, gains were phenomenal
