Microbial catabolism of phytosterol side chains yields C-19 steroids, C-22 steroids, and 17-ketosteroids (. precursors to adrenocortical hormones and contraceptives ).     The addition and modification of functional groups is key when producing the wide variety of medications available within this chemical classification. These modifications are performed using conventional organic synthesis and/or biotransformation techniques.  
You are a couple of superb ignorant dicks.
“My buddy breeds pits and he gives them the roids.”
Holy, you are one special needs little queerbate, aren’t you? That crap is AWFUL for people, even worse for animals. Not to mention, does wretched things to the mind and body. Men that do steroids tend to have major rage issues, and develop tendancies to just “snap” over the smallest things. Pitbulls already have a tendancy to do the same, “snap” suddenly out of the blue. I’m sure steroids will greatly help that issue…iiiidiots. I hope those roided up pups rip your faces off!
On many ranches, weaned calves go directly from the pasture to the sale barn, where they’re sold at auction, by the pound, to feedlots. The Blairs prefer to own their steers straight through to slaughter and to keep them on the ranch for a couple of months of “backgrounding” before sending them on the 500-mile trip to Poky Feeders. Think of backgrounding as prep school for feedlot life: the animals are confined in a pen, “bunk broken”—taught to eat from a trough—and gradually accustomed to eating a new, unnatural diet of grain. (Grazing cows encounter only tiny amounts of grain, in the form of grass seeds.)
