Methinks you've got it backwards NPC. I would say 80% diet/training and 20% everything else. If you took that women's identical twin sister and sat her on a couch and fed her pizza and Bud for life without any weight training , you would have a very different physique. AAS also has no impact on the proportion/length of limbs:torso, or where your muscle bellies sit, or many other "genetic" factors. Between genetics/training and diet I think you have over 90% of what you need to get to national level. AAS is just icing on the cake. Geesh, the number of fat, trollish looking juice heads at my gym is amazing. Sucky genetics, sucky diets and half hearted training combined with lots of AAS makes for a truly ugly body IMHO.
