Woah! Is this your first cycle? You need to do more research before you even consider a cycle, especially w/ Deca.
Many things wrong here:
1. Deca for a first cycle is a mistake. DO you have anything to control prolactin? You do know that Test should be ran at a higher dose than the Deca? You also know you should stop Deca two weeks before the Test?
2. No mention of an AI on-cycle.
3. No mention of PCT.
4. Stats; age, weight, years training?
5. Do you know where to inject, what gauge needle, how much?
I certainly advise you to do more research, however, humans are humans and will do what they want. If you are still wanting to run such a cycle no one will hold you back but yourself. We are here to advise w/ the best possible suggestions.
