Hi, I'm new, and before anyone bashes me, I did in fact read Austinites amazing first time beginner guide. With that being said, I was wondering what you all think about what I'm going to be purchasing soon.

So, as of right now I have test enanthate enough for the 250mg 3.5 times a week (500mg/week), HCG enough for 500mg/week, and the recommended dosage of arimidex . All of which are recommended in the guide by Austinite. My question, however, deals with Deca . I would like to stack Deca with test e, along with the other two recommended substances. I was thinking about 200-300mg a week of Deca along with 500mg a week of test e.

Would this work? Is this a good idea? Or is this a total waste of money?

Open to all answers. Please be as detailed as possible.
Thanks!
