Rich Piana also wore like a size 15 shoe or something, and he's been on record taking 18+ iu/day, but he was a good 6ft+.
Paul dillet supposedly used 18iu/day at 6'1" & never heard of him wearing floppy clown shoes, and I'm sure they're not the only guys running a vial of serostim a day back then. Pro's aren't the only guys who use big doses back in the 90s and early 2000. There are plenty of suppliers who had unlimited supply and were fine with just being gym-freaks, never competing but walking around at a lean 280+ year round. (The dudes you'd see in the crowd at NPC shows)
