i would use a long ester test for your first cycle. if you're going to do gear, do it right. sdrol can be pretty harsh on side effects. its toxic on your organs, can make you feel lethargic, effect your ability to eat enough food, not to mention, you'll be hard pressed to make many lasting gains in 4 wks.
wk 1-10
test e 250-500mg EW, split into 2 injections
an AI like arom 12.5 to 25mg EOD, less is better, IMO, for gaining mass. just enough to control estrogen
wk 12 pct starts
PCT:
wk 1 40mg nolvadex
wk 2-3 20mg nolvadex
this would be ideal and with the right diet, you could gain some decent mass and potentially save yourself from the side effects that could happen with sdrol
if you do decide to still use sdrol, use the same pct i outlined above for 3 wks, not 2 wk.
