There's nothing wrong with deca but when you use Deca without testosterone you will have low estrogen to the point where your dick doesn't work, Deca cycles without testosterone are notorious for erectile dysfunction unless you use a ton of deca so that it produces enough estrogen but in order to do that you would need to take like a thousand milligrams a week. It's pretty simple in the bigger scheme of things you want to use one compound for your first cycle so you know how it works and you know how to manage side effects and stuff like that. If you take multiple compounds on your first cycle and you start getting side effects you will have no clue what drug is causing what side effects and it turns into a nightmare for most guys. So the best plan of action is you want to take testosterone and then maybe after about 6 to 8 weeks you will know how your body is responding to testosterone and what kind of side effects you're getting and then if you want to add something else like an oral or Deca now is a good time to do it, but Deca also has a very long half life and it takes quite a while to see noticeable effects from it, it's working right away but it takes a solid 6 to 8 weeks before you actually visually can tell that it's working. So for this reason if you're going to add Deca late in the cycle use NPP instead, npp is just fast acting deca.
For long Ester testosterone you want to inject a minimum of two times a week but I prefer to inject every other day or daily. NPP is fast acting and you want to inject it daily but every other day will work as well.
Skip the Deca and orals for now and get some testosterone and inject 100 mg on Monday Wednesday and Friday for 300 total or if your product comes 250 mg per milliliter you could just take one half CC on Monday Wednesday and Friday to give you 375 mg per week. That about 8 weeks down the road you could make a decision on extending your cycle or whatever you want to do at that point.
That in my opinion is the smartest way to run your first cycle
