14 weeks is totally fine..... I would stick to a 12 week cycle I would stack it with D-bol

run it like this
500mg sus a week 250mg on monday 250mg on thursday
40mg of D-bol a day split over the day for the first 3-4 weeks of the cycle

week1 testsus dbol
week2 testsus dbol
week3 testsus dbol
week4 testsus dbol
week5 testsus
week6 testsus you should be feeling like a freight train
week8 testsus
week9 testsus
week10 testsus
week11 testsus
week12 testsus
week 13 start taking vitamin D every day
week 14 keep taking vitamin D
week 15 start PCT with Nolva ~ Clomid and vitamin D
week 16 PCT

Remember to leave room in your diet gas tank to be able to eat more after your cycle to keep the bulk on. Try to eat as clean as possible

Also get some ADEX for gyno.
