I am 30 year old, 5'8" and 79 kg. I am doing gym from last 1 and a half year. Initially my aim was to loose weight (at that time I was 85) and after loosing weight (I came down to 74 kgs in 6 months) I started doing more and more weights.

From Last 1 Year or so I have been doing Weight training and I am pretty motivated and dedicated towards it. After seeing little improvement in my measurements I decided to start power lifting (Thats what my trained adviced to me). I Have been doing power lifting from last 2 months and the only supplement i take is ON 100% Whey. I am taking 3 scoops in a day. 2 after the workout and 1 in the night.

In the last 2 months itself i have increased my diet and thats why i have gained some weight. I want to add some muscle to my body. Please recommend if i should start taking any pre workouts now?

If Yes, Can i go for Jack3d, as i have heard great and great reviews about it. Will it be okay for a guy like me or should i start with a "lighter" product to begin with or should i be even thinking about taking pre workouts?

Please help me out. Thanks
