So I’m not a vet but how it was explained to me is that ProStride and IRAP have many of the same proteins and platelets and benefits, but IRAP has more (due to the processing time and the fact you do 3 treatments instead of 1). ProStride still packs a punch, but IRAP does “more”.
I don’t have time at this moment but I found some really good articles comparing the two when I was researching - just pay attention to the source!
