I did 7 months,,afterwards I was sick as a dog.....Your immune system crashes too hard after a long cycle.....I suggest front loading hard going down every week for 5 weeks then change your drugs in week 6 and do the same,,front load high then go down every week.....Of course your androgens always the 1st 5 weeks anabololics your your last 5 weeks...youll get awesome results and not get the crash...
