For those still curious, all hormones act the same way. They can diffuse in and out of cells freely. Insulin works like that (thank goodness, if you're a diabetic). A tiny amount injected under the skin does the job. So, those implants diffuse into a steer's body and get broken down by his liver into various forms that can also diffuse about and cause effects. Eat the steak a bit of that goes into your body. Does it do anything? Eat a lot of steak over time and all the tiny amounts add up. But what effects do they have? When they are broken down by our livers, what can they do? Are they little crazy drivers in a city that don't end up hitting anything, or do they wreak havoc over time? That's the question. How did they get approved for use through the FDA? I was taught in college animal science that we lacked the receptors. Its not that simple. Obviously. The manufacturers have receptors they are targeting to influence growth rates, and it is true that we lack those specific receptors. It is not true to say that these hormones have zero effect on anything but hose receptors in either the stees body or ours. We know some of the outward negative effects (aggression). There is no way to prove no effect because we don't understand all the effects and pathways our own hormones have. Nor can we predict what shape the hormones will become after our livers have broken them down. We simply do not know. Lots of things are approved by the FDA because no specific short term harm can be proven. Look at the crazy food additives and food dyes we tolerate in our foods. Sometimes it's also a matter of influence or money changing hands. Keep your eyes wide open.
