I need to bench 400 pounds before 11 sep You bench more that 99% of the Teen BBing forum. You clearly have more knowledge then most people on the subject. All I can tell you to do is start taking creatine if you haven't, it can help your strength alot. Also start a lean bulk, You said you can put on 5-7KG which is what 10-14lbs? You have basically half a year, you could easily lean bulk up 10lbs and 10lbs of LBM should add greatly to your bench. I only bench 270lbs, but my bench 7 months ago was 175lbs so I feel like I am doing decent.
