I don't see what's there to flame when we all start somewhere, we're all here to learn and we're all here to make progress. But that being said, 14% to 16% a little on the high side, and certainly a range that I would not want to start a bulk at. You have to remember that your body would always want to stay in a state of homeostasis, meaning that your body wants to stay in the same state and is not very willing to change. So going by this, bulks should always start from a very lean base, single digit body fat levels if possible, to maximise what you can get out of your cycle. You will notice that between starting lean and starting at higher levels of body fat, you could gain the same amount of scale weight over the same cycle, but the composition of this weight gain will be drastically different. If you start lean, you're going to put on more lean mass.

I'd say if you're gonna run that stack, drop the bulk bombs and focus on leaning out first. You're a pretty strong guy and you seem to have good genetic response with recomping (when you say gain muscle but not gain weight), so I'd say drop the calories a little and focus your training on maintaining that strength you have. Wait till you get a little leaner, then you could pull out the Tren, up the Test and throw the bulk bombs in to grow. That, or do a Test/Deca cycle. You do not want to run Test/Deca at your current body fat levels because it'll just make you look bloated and mushy - always start lean when you're using those compounds for the best benefits.

Now if you do decide that getting lean isn't in your interests or goals and you just want to grow, then I'd say keep the Test at 300. No point increasing when you're already running a pretty good amount of everything else. For AI you can use Aromasin or Arimidex. Keep it on hand and only use it when you need to.
