first things first, Arnold was born with a heart defect.
I started using steroids when I was 20, for no other reason than I 'felt like using them'. Would I go back and do it all over again if I could?
Absolutely.. though I would have never PCT'd and just blasted/cruised (which I started doing when I was 22).
injectable steroids by themselves are not nearly as dangerous as many will have you believe (unless you have underlying health issues/genetic predispositions).
it's high doses of injectable steroids, combined with high doses of GH, ran for extended periods of time. Add insulin, lots of oral steroids, stimulants like clenbuterol, diuretics to get ready for the stage, and painkillers to help mask the pain from joint issues from moving ridiculous amounts of weight for years.
I think you get the picture..
on blasts, stick to moderate doses of testosterone about 1 gram/week, maybe 600mg of EQ/week (im not a big fan of nandrolone decanoate as it is bad for blood vessels), NPP would be fine to rotate with EQ I guess since it gets out of your system faster than the decanoate ester thus helping to mitigate the damage.
and you shouldn't really need more than 400mg of tren a week.. maybe a moderate dose an oral like dbol if you are trying to grow, and anadrol if you are going through a diet phase (anadrol tends to reduce appetite, so it's beneficial for dieting periods as it is also very good at preserving strength and size under caloric restriction. if anadrol doesn't reduuce your appetite, it'll be very good for growing as well).
blast for 10 weeks, cruise for 8-10 weeks (longer cruise if you want...)
cruise dose should be 200-300mg of testosterone/week
letrozole will be your AI of choice.
use tudca, curcumin, vitamin k2, a good fiber supplement, fish oil, and nac, and you should be just fine.
keep your blood pressure in optimum range, don't drink alcohol, and eat a clean diet, dont get fat, and you should be just fine.
