Not a whole lot has changed. In fact the not-so-well-understood peptides are just further increasing any dangers. There's probably better AI's available nowadays.
HGH is probably 1/4th the cost it was back then anyway. IGF has certainly come down in price.
AAS + GH/IGF + SLIN + DIET + a lot of time in the gym = what it takes to create those kinds of monsters. Any other little supplementary thing might get them a lb or two of lbm.
In reality most people shouldn't go chasing this lifestyle. In fact, I don't even think its cool to look that big anymore (in most places of the country). I'll quote my workout partner: Once you get too big you stop attracting girls, and start attracting guys.
