you can only bench your weight. why is that? you may need to re-evaluate your workouts. OR
have you done a blood test lately? i have a sneaky suspicion after all these cycles you have done only being able to bench just ur bw that you have severe suppression. did u allow yourself to recover before all those cycles? i bet you jumped on a new cycle too fast. hope I am wrong.
after all those cycles to still not be where you want to be is a little scary. and you said you are a bulky guy, you should be able to bench 125+ pounds more then you weigh. I'm 185 and maxed out 315 and thats just after 2 cycles. that is a good standard for a steroid user who is experienced. some of the guy on here can get close to 2X their bw.
post up some pics, your test levels, diet, and even bf% (dont estimate, get it tested) .. that would help a lot evaluate what is going on.... we will definately be able to steer you in the right direction with the right information provided.
