hi chalk
what is your training and cycle history?
superdrol is a steroid - read this post

if you do qualify as ready to use them (!) then it was effective for me, i gained 16lbs in 4 weeks (9lbs of which i kept), for a first ever cycle.
However, i regret doing a second cycle only 8 weeks later, as i had worse side effects.
you can see my remarks about superdrol in my log here:
