I thank GOD I have come across Doc David Bieber, his research on testosterone replacement therapy saved my English Bulldog. Busta was 10 years old when he had to get back surgery a few months later, long story short Busta had to get "fixed" and his health started declining. Doctor Bieber went above and beyond to help Busta. His TRT "testosterone replacement therapy" help busta in so many ways. Busta is more alert his back legs are strong again and he is a very health 13 year old English Bull....please go see for yourself how good Doctor Bieber is.....
