I would say a proper introduction to the forum first.
Then a bit a searching on test and deca if your set on it. But based on the, “ are they safe to use” not much research has been put into your search. What someone is telling you should have a degree of impact on your choose to start I suppose but you need to put in the work understanding the compounds and what they do that the body more than knowing they add mass or cut..
What workout programs do you or have you followed?
Have you gotten blood work done?
I would say you probably could achieve your goal without gear.
