npp question

[ssilver7]

so i understand the basics of how much to take and what to take with etc....currently i am using supertest and parabolan, im using parabolan for 8 weeks and im wanting to use npp directly after to finish out my cycle so, i was wondering if i should start running the npp prior to finishing the parabolan, maybe a week or two early to get it built up in my system by the time the parabolan runs out, or should i wait until after the 8 weeks since using both would be a lot of progesterone and ive been told not use both at the same time

para is at 100mgs per week and im wanting to run npp @400 and im thinking about anywhere from 12 weeks to 14 weeks not including pct depending on when i would start the npp
