Best drug for lean and hard muscle gain minimal bloat and sides,,,but increases sex drive for women...the drug ...the dosage.....and the lenght of time of cycle........win, ox, primo, deca, ??????/
But seriously, amount of bloat is going to be an individual thing, but can also be determined to a degree by how clean the diet is too. I think anavar has been shown to retain a significant amount of lean muscle and probably the least amount of sides too.
