drol is great when cutting down.
most I know dont' get puffy from drol the way you do with dbol... makes me suspect what ppl are taking thinking is 50mg drol, is actually 25mg dbol.. anyways...
with drol, in my experience personally, and those I train, you stay fuller and harder.. like you hold water 'inside' the muscle, as opposed to sub-q (like with dbol).. also stay vascular.
I've never had noticeable effects when used pre-workout, however.
'offseason' big and puffy - test, deca/npp, dbol
'picture time' hard and separated - test, tren, drol
