Add former UFC light heavyweight champion Quinton ‘Rampage’ Jackson to the growing list of UFC fighters on testosterone replacement therapy (TRT). Quinton admits in a recent interview with Fighters Only that he was recently found to have low testosterone in his older age (33) by a doctor  and was recommended to start TRT. The therapy had taken place prior to his last bout against Ryan Bader and was said to have helped the recovery of a cited knee injury drastically.

I almost pulled out but then I went to see the doctor and he told me to talk to an age-management doctor. So I went and talked to them and they tested me and said my testosterone was low; they prescribed me testosterone, to bring my testosterone levels back up to levels where I can be like… so that I am the same as young people, like when I was 25, and it would help build my knee up. I hurt my knee like a month ago and I only did three shots of testosterone but it put a lot of weight on me, a lot of muscle on me but it healed me knee up good enough to where I could fight.”

Rampage went on to say that the therapy worked so well that it is the reason for his new drive to continue in mixed martial arts.

I gave myself small doses and that shit immediately changed me, that’s why I am saying now I am not going to retire. I am not gonna retire no time soon, its just unfortunate that I got this injury. I started hitting it up pretty good, I still gotta take care of my knee but I feel like a 25 year old again. My sex life changed, I was back to five times a night like when I was 25, straight up.

“So I spoke to the UFC and they were like ‘yeah, a lot of fighters are probably doing it but not telling anyone.’ Me, I keep it real, I am not doing anything wrong. Its legal and I am not abusing it and I am not going over certain levels. From what I learned about it, when I got tested my levels my levels were really low and the doctor was telling me that athletes can burn testosterone.”
