Hi My Age Is 33 Years, Weight Of 72 Kg

Hi my age is 33 years, weight of 72 Kg and I am regularly doing weight training. To get better result since from last month I have been using whey protein powder. But I felt tired during training season and could not able to lift desired heavy weight. So, I have been taking Liver tablet liv 52 and Multivitamin A-Z; whey protein also taking along side.

So, pl advice whether I should go ahead with this procedure or may be its risky.
