Had a friend in Kentucky who worked on one of those therobred horse farms where the horses would be auctioned off at an event somewhat similar to a bodybuilding contest.
Seriously !
The horses would be brought out individually and stand in various poses - front, side, and back. And then the bids would start and one by one, they'd be auctioned off to the highest bidder.
I asked my friend how these horses got so muscular he said, "Wait around and I'll show you the 'med center' in the back". BTW - My friend had just won two state bodybuilding championships within the past 12 months.
When we reached the "med center" he opened one of the refrigerated lockers and showed me stacks and stacks of steroids - Equipose being the only one I can actually recall.
"Equipose works great. That's what the horses are on and it's real clean for human usage too! Wanna shot?!" And then he started counting the supply with his foot and galloped around the room a bit.
How popular is "Equi" today? Anyone know? Must be a lot around since the horses stopped using it.
