i havn't ran katanadrol itself, but have used the compound found in katanadrol (furazabol-thp ether)
some people have good results with 250mg e/d, me personally, i would recomend you run it at 300-500mg for 6-8 weeks.
stacked with something like hella, keep it in the 300-350mg range for 6-8 weeks.
expensive? yes. safe? yes (gotta pay to play). results? you will love it.
toss in some transaderm for a test base, and get you swole on ninja.
