My six year old stallion has a huge sarcoid on his left testicle. We have tried a topical cream from the vet and a natural option from here in the states. The medical cream did jot do anything. The natural avenue did halt the growth but there was no reduction in the sarcoid. It has gotten really big (even since this photo which was takena month ago) but I do not want to castrate him. I'm happy to give anything a try!
