My girlfriend is a horse trainer and gets winstrol v from her vet to cycle her race horses. She gives them five cc's every two weeks. I know for humans its best to inject winny everyday, so why is there such a big difference in the way humans and horses cycle winstrol? I thought she was doing it all wrong so the last time she went to the vet I went with her, she was getting some more winstrol to cycle two young colts with and the vet told her to just give the colts three cc's every two weeks. So if the vet told her this then it must be the right way to do it. Hopefully somebody here has a explanation of why cycling horses is different then humans.
