ProBoost, Thymic Protein A (TPA), 12 Packets with 4 mcg TPA/Packet - Immune Support Supplement by Genicel, Inc.

I have a small kitten that we found out when he was suddenly very sick that he has feline leukemia. We almost lost him but our vet told us to try this on him along with a high quality kitten food. My husband and I did not want to give up on this tiny family member so I have used it for a couple of months. I sprinkle a little bit each day in his food. He is almost completely well and is doing great running around like any other kitten. He is inside and we would not let him outside to risk for other animals but I cannot say enough about this. I do not know the long term results for him but will continue to give it everyday in his food.

I have used this remarkable product for many years. It is a superior immune boosting preparation that should be taken at the first sign of a cold. Every time that I have used it, my cold is either aborted or shortened to a day or two of mild symptoms compared to when it is not used. I have recommended this to many friends who also have had similar results. Of course, no one supplement works for everyone; but this is among the best that I have found.

I didn't really notice a difference. . .

I use it as part of an antiviral protocol from Dr Marty Ross.Very effective

Great product, terrible value on this box of 12 packets for $25. Bad on me for not reading the product description and thinking I was getting a deal, when it's generally 30 packets for $40 ($1.33/packet vs $2.08/packet for this ASIN).

Arrived very quickly. Good product.

Didn't do anything for me at all. Can't really say more than that.

Great!
