zyzz died young, but it wasn't from steroids. it was a combination of dangerous habits. did the steroids possibly speed up the process? yes. but they weren't solely responsible
taking DNP, diuretics, and clen are way more dangerous than straight anabolic steroids. plus zyzz would sweat out so much water in the sauna that he wouldn't hydrate it back. he was obsessed with that dry look way too much
the young boy probably died from the above, or he could have abused orals and gotten liver damage. hard to say without more info
the older folk will have heart strain from steroid abuse and what ends up happening is they run into heart problems, steroids absolutely speed up heart issues. so you should keep a close eye on your heart lipids via blood work and bp checks. if you let it get out of control it will bite you
