Assuming that you are just adding in the sust to avoid "deca dick" I'd say that cycle is cool. I generally like to use dbo a little bit longer than that, but that's not bad. Don't forget to get clomid too.
No actually I never tried deca before. This is my second cycle. My first cycle consisted of
500 sust 10 weeks
30mg dbol 3 weeks
clomid of course
but that's it is there something I should know about that amount of deca. Should I cut it to 250. I would like to get cut up on this after this cycle is over.
