Component TE-S in process granulation is the only one I would mess with and it would have to be cheap. you could salt the estradiol out and recover the TA. but with what TA powder cost you would be hard pressed to make it worth while. And it is no more legal to do that then buy the powder.
As for injecting any kind or estrogen well yes your going to get huge on it. That is why they mix it in all the cattle products in the first palce. Then again noone care that fred the steer has a bad case of man boobs, we don't eat that part.
