its hard to pinpoint what gains will be. Too many variables but set goals that are achievable and then it was a good cycle. My last cycle netted me 10lbs. This time includes the three month on period and the 4 month off period. People would say that is very good gains. I have a diet that is very good. I train 4 times a week hard.

Mathemetically you can figure if you add the deca now then you will end up in a 14 week test cycle and 10 week deca cycle. This is your choice, its 2 weeks too many from what I thought a last week when guys have been reccomending on this board I run a 16 week cycle, 12 weeks of test, 10 of deca and 4 winstrol. From what I understand winstol shuts your system off just as test would. So your probably fine.

You will need to get more test. You should always have a little extra when doing a cycle. I have broken bottles and amps and lost entire injections.
