If you found information on running a long ester for only 8 weeks it was the wrong info , people write shit because people read shit . No less then 10 weeks , but you will find your most impressive results around 12 weeks . But none of that matters if your diet is not number one priority . Slow down read a little more . Your first cycle will be your best most likely so do it right and fallow everything to a T , in 2 years when you decide to run it : D
