Yes and please don't get an infection on injection day LOL Just kidding biggen'.
Seriously though good advice on both parts here so far. I'd say if you haven't already gotten the sust just get some test ent, cost less and will give you the same results with less fluctuation. On top of you being larger then the norm, like Pain pointed out that cycle you had originally laid out will almost definitely not give you what you're looking for. I know a few guys who had run cycles like that back when I was younger in fact two brother in particular.
They both had decent builds but still plenty room to grow. Roughly they put on around 20 lbs. The one stopped training and dicked off. The other held on to his gains by continuing to train hard eat right and doing the right things. They both went back on the SAME exact cycle and guess what the one guy gained back his 20 lbs pretty damn quick, while the other brother didn't gain much more then 5 lbs. I know its not the most scientific example, but I'd say you ARE the other brother.
You're already a big guy and that cyle you laid out probably won't do much but make you a little hornier, maybe cut your recovery time a bit, and at the most I'd guess you might gain 5 lbs or so. On the other hand the cycle that Pain laid out wich is NOT really by any means a crazy cycle should give you some really decent and solid gains (I'd guess more like 10-15 lbs when all is said and done). BTW, are you going to use an ai throughout and like Bushy said what's your PCT looking like?
