"This stuff is a miracle! My 11 year old yorkie had a bump on her stomach. Vet wanted to do a procedure that was going to cost me a fortune to remove it, but I’ve heard about turkey tail so I decided to try it. It’s been two months already and the bump has become so small you can barely see it and her energy is like a puppy the vet were surprised, can’t wait to purchase more I totally recommend this."†

"10 months ago my 7 year old lab mix had a splenectomy due to a very large tumor on her spleen. The tumor came back as a hemangiosarcoma and she was given 4-6 months to live. The vet recommended I start her on turkey tail, as many animals had good success on it. We are now 10 months post splenectomy and she seems to be doing fine."†
