try giving a little more information if you can, just knowing that your on test e and deca is not real helpfull....how much, how old, stats etc are a good start....then we can give you a better idea of your pct....for starters deca and test e for 8 weeks is not really my strongest recomendation.....by the time the deca kicks in your gonna be stopping it 3 weeks later.....should be a 10 or 12 week cycle to enjoy its benifits....M-
