do you think I'm ready for a 1st cycle ?

[Trippensee]

I would like to try a first 300 or 400 mg/w T enanthate @ 10 weeks cycle.
actually my routine is
day 1 : chest
day 2 : biceps/triceps/forearms
day3 : delts
day 4 : legs
day 5 : back
week end : rest

my diet, I don not really pay attention to it, I eat many carbs and take whey to reach proteins needs for BB. more or less 0.331 pounds/day

This is just my input, not sure if everyone will agree. You should fix your routine a little. You categorized arms into one day which shouldn't be, in my opinion. Biceps are pull muscles and triceps are push muscles. Why not work back and bi's on day five and chest and tri's on day 1. Then for day 2 you can incorporate ABS into your workouts. Your bench probably hasn't gone up because your core isn't strong enough? If anyone disagrees let me know and i'll edit.
