You'll excrete an excess of urea. Save the stress on your kidneys and your wallet. I've had great gains in the past with less protein. I usually try to keep it a little over a gram per lb of body weight.
I ran two cycles when i was 23/24 reccomended from old mods on this site. Well, I just turned 28 and I'm back down to about 185 @ 6'. This was due to competition in BJJ and lack of lifting. I'm ready to put on a good 25-30lbs again. I am unsure what new kind of gear is out there, what's safer...
