I was running tren prop winny last spring..... i cut both the prop and the tren about 15 days before the winny (ran out) didn't think it would be a big deal. I also didn't run any hcg (STUPIDEST THING ASS WISE I'VE EVER DONE) and when i went into PCT, clomid/arimidex and herbs, i was shut down hard... libido, gone, sex drive gone... i'd get periodic hard-ons of little convience.... it sucked ass for a long time... if i was smart i'd have done my pct over again with hcg... I had just moved and had little sources.... dumb dumb dumb... So as for my advice, as long as you're running test i think you'll be fine, but when you come off get that HCG in you ASAP!!! (PS- as of current i'm on test E 750/wk and tren E 600/wk and my girlfriend is scared of me!)
