If your going to insist on doing this then take the nolva at the end of your cycle, three days after you take your last tablets. Take 50mg a day for a week of nolva then 25mg every day for three weeks...
You should have seen some gains already, has your lifting weight increased? First off, what is the count of your reps, sets, and what is your lifting weight, for bench press, has it gone up? What is your supplementation like? I am a certified personal trainer, so feel free to ask anything.
8 to 10 reps at 75% to 85% of your one rep max! With this you utilize more muscle fibers, therefore you grow more. Just be sure to watch and NOT overtrain.
