What's your age and stats.. It sounds like you don't have a clue what your doing, so I'd advise not to take anything tell you've got it together.
Your going to need testosterone in order to run either of those compounds. Deca takes 8 weeks to kick in, you wouldn't want to start it late into a cycle (I advice you don't take it at all on first cycle,, unless you like having a limp dick).. You need to have an AI and run it the duration of your cycle, that keeps estrogen in check and keeps you from bloating and getting Gyno,, save the nolvadex for pct, get clomid too...
After knowing age and stats guys here can help you put a real cycle together. In the mean time read the stickies and educate yourself
