KYZATREX Patient Testimonials

“I have experienced a jumpstart in health which I attribute to KYZATREX; I have recently taken my health into my own hands after my labs reflected low testosterone. I have been on KYZATREX for more than 4 months now and my testosterone levels are back to normal. My life has changed for the better. I really do attribute this jumpstart in health to KYZATREX.”

Bryan N, 56

Real Patient Taking KYZATREX

“For years I used testosterone injections but wanted to switch to an oral TRT. My doctor recommended KYZATREX due to its tolerability and side effect profile and I’ve now been on KYZATREX for 8 months. My testosterone levels are about 700 ng/dL and I feel just as good, if not better, on KYZATREX than I did on injections.”

Brian R, 47

Real Patient Taking KYZATREX

“When I first discovered I had Low T, I went with pellet therapy. While pellets seemed fine at first, they eventually became too much of a hassle – the painful implant process, scar tissue buildup and activity restrictions just weren’t for me, especially when the effects started wearing off before the next dose. As soon as I heard there was an oral option, that’s when I switched to KYZATREX. I love the convenience of the capsules, and my testosterone levels are in the normal range! It’s made a real difference in how I feel.”
