You can run DECA in long duration cycles like 12-16 weeks however I would never suggest running it non stop year around.
Me either. I usually run 10-12 week cycles two times a year. I run 150mg a week. It does wonders for me along with my TRT Test. I gain quite some size during that cycle. You have to watch your prolactin levels. I take .25mg of Caber every 4 days. That does the trick and keeps away the dreaded Deca Dick! Deca is good in my book.
