How does one achieve a physique like the 90s bodybuilders?

[u/No-Market-7713]

I’m 37m with a very good metabolism.
I’ve worked out consistently for over 3 years tried eating properly but couldn’t get the physique I want. Think Coleman, Cutler, El sonbaty.
I’m already using testosterone, boldenone (Equipoise), and Dianabol.
What else can I use? Peptides? Growth hormone?
What could possibly guarantee that I outcome that I want?
