M1T blew me up from about 210 to 240 in 4 weeks, so I'll go with that one. It wasn't pretty but I was much bigger.
well you can take winstrol off of the list.
I think 4-6 weeks is way to short for mass gains, i would never run just 4-6 weeks
i picked anadrol both the bd and british disp were good to me. but the best mass idea is 50mg anadrol and 50 mg dbol thats wuts given me great results
