Hard to believe someone could gain 14 lbs and increase their bench by 50 lbs in 2 weeks off of deca alone. The decanoate ester is very slow acting and even if a different (faster acting) ester is used, nandrolone alone is not usually that strong. Gains are generally gradual.
2) Why 500mgs week one and 400mgs week two?
and what is the strength of deca per ml?
I am not trying to be a jerk but your posts seem odd to me.
Even if you said your friend used test E with the deca the first two weeks, those results would still be hard to believe.
Enanthate is also rather slow acting.
