Deca, masteron test

So I have deca 300 coming and masterone, this will be the second time ever trying any type. First one I’m not sure if it was even legit. Any input or recommendations on this topic would be greatly appreciated. I’m currently on 200mg of test c per week and looking to add

The info you provided as well as your question is very vague.

So you are using 200mg Test Cyp per week and want to add Deca and Masteron. What exactly is your question?

What is your weight, height, age, caloric intake, previous course experience?
