    15 Nov 2025, We noticed blood droplets on the wall from frequent coughing at night. Yuki had an echocardiogram and X-ray due to a heart murmur. His heart was OK but an incidental finding from an X-ray showed something close to throat area. He coughed up some ligament like pieces with his phlegm and lab results indicated malignant cells. There’s a lump on his neck area. Yuki had to take phlegm and airway medicine to help his cough but it lingered for a long time. It seems like the blood in his throat possibly caused bacteria infection and a course of antibiotics helped. Around mid Dec 2025, Started pet Yunzhi. After taking Yunzhi, his cough seemed to improve slowly. By early February 2026, the big lump on the neck became 2 smaller lumps. By March 2026, can hardly feel the lump anymore. But of course, that doesn’t mean the malignant tumor is gone. Yuki had Horner syndrome in one of his eye and vet said that his eye seems to have some nerve problem and that could possibly be from the tumor. Yuki quality of living improved after taking Yunzhi for a month. Right now, he doesn’t seem to have any discomfort and he eats, plays and sleeps well.

    Our baby had sudden pain and her vet found her bleeding internally. We rushed her to the emergency hospital and they immediately performed a splenectomy. She survived but was diagnosed a few days later with Hemagiosarcoma. We were devastated but decided to meet with an oncologist to know her chances of survival. It wasn't good but we decided to hRead more about review stating Caramel-5 year yellow lab-Hemagiosarcomaave her go through chemo. After a lot of research, we also learned about a lot of natural supplements including turkey tail. This lead us to the study they did using I'm Yunity. She just finished and had her 5th and final chemotherapy treatment. Her staging saw no sign of metastasis. We know that the cost of I'm Yunity is expensive, but we feel we have to give her the best chance to live as long and happy as she can. She just made 4 months, something we never thought we would see. Her smiles and happy self reminds us that she is worth it. Any time we have with her is worth the sacrifice we have to make now. No regrets!!

    Cooper, our 11 y/o Beagle w/ Hemangiosarcoma (initial indication via mass on spleen) was given 1-3 months to live after a splenectomy and removal of a grapefruit sized mass that ruptured in May 2024 and here we are approaching 9 months (GOOD months with slow progression).

    After the emergency surgery to remove her ruptured spleen and the hemangiosarcoma diagnosis in August 2024, I did hours of research and found the UPenn study. Every vet I spoke to, and the pathology report gave my girl 1-4 months, maybe 6 with chemo, which we didn't do. No one had heard about I'm-Yunity or turkey tail mushrooms. Ordered the I'm-Yunity aRead more about review stating Amazingnd started 8 capsules a day (4 with breakfast, 4 with dinner). We are now at 15 months and she's still doing well.

    My dog Hope underwent a splenectomy in October 2023 with a biopsy result of hemangiosarcoma. At the time of diagnosis there was no further metastasis. She was a 53lb lab/ pit mix who I had been feeding part Ollie and part homemade cooked meat veggies with turmeric.

She also had been on Rejuvawafers by Sun Chlorella and CBD oil and chews by Elle Vet. I recently had to say goodbye to her at almost 15 years old January 2025 due to the return of cancer on her liver and everywhere BUT her heart and lungs causing extreme chronic anemia that could longer be treated even with transfusions I eventually started her on Yunnan Baiyo and Blood support capsules combined with this but I think a little too late so just a recommendation to others. The 15 months were all good quality except the last 3 weeks. I would highly recommend this product.

    In April 2019 our little 8lb chihuahua had a splenectomy due to a mass on her spleen. Ultrasound indicated it was likely benign. It turned out to be a highly aggressive cancerous tumor and we were told there was only one other dog on record with this type of tumor. The vet suggested an aggressive treatment similar to hemangiosarcoma given the typRead more about review stating Rare Literal Cell Angiosarcoma of Spleen of tumor and with still poor prognosis. . Given she was 13 years old with heart disease, we decided not put her through it and just let her be happy for whatever time she has left. The vet suggested I'm-Yunity which we started right away. Well, it’s been 2 years now and our little chi is now 15 and doing great. The vet is amazed she’s still here and has no signs of any cancer. Maybe we got lucky or maybe this stuff really works! We’ll never know but it’s certainly worth trying if you’re looking for an alternative to traditional treatments.

    My dog is in his final stage of cancer, and I just wanted him to feel comfortable. I received the package just a few days after purchasing. After taking I’m-Yunity® (For Dog Use), he's been doing much better—he's even able to get up and go for walks again! Thank you so much for your quick help.

    My 16-year-old poodle, 'Boy', was at the end of his days due to organ failure and cancer. He couldn't stand, walk, or eat. My friend introduced me to I’m-Yunity® (For Dog Use). After taking it for just two days, Boy was able to stand up, had his appetite back, and could walk around again! He lived for another 2.5 months in a much better state before he finally left us. I'm so grateful and would greatly recommend this.

    I have two dogs which have been diagnosed with hemangiosarcoma 4 months ago. We had a difficult surgery to remove the spleen and the diagnosis was that this type of cancer is very aggressive . Thankfully I have found I’m-Yunity and my dogs are extremely healthy and I will continue this treatment.

    Our dog Thor was diagnosed with Spleen cancer two years ago and we were told he had about two months to live. We found this product online and decided to give it a try. He took it everyday and we got two more awesome years with him. He passed away last night, but without this wonderful product we would have never had these two extra years with him. Read more about the review stating that it gave us two more great years. Thank you I'm-Yunity.
