do not look into Gakic at all...MuscleTech supplements are a joke. Everyone i've heard that has taken Gakic feels horrible after their workout and really don't notice a difference in performance.

You say you want to lose 20lbs of fat, and gain muscle...you probably need to pick one or the other to do first. Either cut the crap out of your diet and focus on the cardio portion of your workouts to cut fat, or bulk up and then cut the fat (the more lean muscle you have, the more calories the body burns just in daily maintenance, so bulk/cut is the route most people use)

Go do some reading on these topics at bodybuilding.com or bulknutrition.com

and if you're looking for a legal supplement...try Superdrol...it's a prohormone, but it is legal and will be sold on bulknutrition until june 30th for $19.99 a bottle...just read the comments on it and do some research because this supplement requires that you do a few other things to take care of yourself during the cycle and afterwards.
