i agree with Reggie on this one, horrible stack, not good to go men, 
im litle bit confused here about this compound,
cuz: 2,17a-dimethyl-17b-hydroxy-5a-androst-2-ene = Dimethandrostenol
and 2a,17a-dimethyl-17b-hydroxy-5a-androst-3-ene = superdrol
and 2a,17a-dimethyl 17b-hydroxy 5a-androstan-1-ene-3-one = Methylstenbolone
17a-methyl-1-androstene-3-one-17b-ol = Methyl-1-testosterone
17a-methyl-17b-hydroxyandrost-1-ene-3-one = Methyl-1-testosterone
They are methylated at the 2a and 17a positions, but still very unsure about this TANK compound and what it really contains?
as we said, run something else specially if u are worried about water retention, it may be strong prosteroid but very long list of side effects, Run something dry without water retention problem something like: SD-tren-methylstenbolone-epistane-halodrol-furuza-bold, etc etc:
