Give it time bro! One time I didn't gain anything for 8 months, and that was after a year of lifting! But just give your body time to grow and rest and you will...
As for your question, it is clear you need to do more research. Hit the drug profiles section hard on the main page. Don't do a deca only cycle, throw in test and dbol for the beginning. Research good stacks and dosages if your mind is set.
Research is the key bro!
Good luck.
