Bro I must agree with the other brother’s advice npp, if quality is good shit. I’ve been running it every bulking cycle and have even used it for cutting. For me I alway cut my test to 300mg, Npp 450/500 wkly, mwf ;100mg T, 150mg Npp. For me keeping my test lower kept my estrogenic sides down. I also used letro at 2.5mg wlky works wonders for me every time. I’m one that get bloodwork done periodically and usually run this cycle 16wks before cruising 6/8 weeks. Good luck!!
