I ran 300mg/week deca only...got some muscle and shredded at the end....some people dont get deca dick...,i did bad...first couldnt bust a nut for like 2 hours (not like my girlfriend minded) then erecrion problems that lasted like 5 months....im running deca/test E 250mg 6th week in, by this time i was already having dick problems......none now! Test is the key get a good pct lined up...run test 1 week longer than deca and 7-10 days after ur last shot start 40mgnolvadex and 100 clomid for a week or so drop it down to 20nolv/50clomid for about 4-5 weeks total HCG is an option too get the boys back to size =) Good luck!
