I'm with gashred, a twenty week cycle is ridiculously long and thus dangerous. So I will urge you to run your current cycle in its current configuration for another two weeks, run a proper PCT and then, three months later, launch your test', tren' and whatever else cycle.
Too, I find myslef distressed over your admission that you don't know how many cycles you have run. That kind of sloppiness is indicative of someone who does not take his use of AAS very seriously, and that, goatrep88, is very dangerous. You need too be keeping detailed logs respecting everything you do. It is just that important.
