Test prop at 350mg/ew with some orals for 6-8weeks gives me pretty good gains. Also fast recovery and didn't need a PCT. I think this will change with age, recovery will be slower and PCT will be a must.
I have read and heard different things, some older guys have told me 6-8weeks on 6-8weeks off is the way to go.
But I've also heard and read that gains made 10-12+ weeks are easier to keep since 6-8weeks is a short time to build muscle.
For me growth stagnates usually around 6-8 weeks.
Hope more of you guys will talk about your experience and shed more light on this topic.
