The only question is, why is it so rare to see these tumors then? (In the case of LITF everyone is totally shocked). There is no doubt in anyone's mind to many "meds" are used and to horses detriment by everyone. There is no doubt 2 year olds are pumped up by steroids, so why does this seem to be rare if it is the cause in LITF?
Some info on clenbuterol.
