Starting lifting with 16 y/o and I am currently 23 y/o, I have gyno from puberty, to counter it I have been always on one digit of BF 5-7%.

I started my first cycle with 50mg Test prop, 50mg Tren ace,50mg Masteron EOD and 25mg proviron ED, I have completed today the third week... My question is:
So far I have gained 20lbs will my gains keep coming? I am currently with 8% BF (same machine as always), I don't see an increase in vascularity but maybe because I was already veiny as hell also I have to mention so far I had zero negative sides.

p.s. I am doing a clean bulk and I am a bodybuilder, the man that is doing my prep told me to not do PCT instead stay on TRT till next cycle... is it wise?
