I feel better than ever!
When I was reaching my late 40’s I felt like I had less energy and was tired all the time. I just figured that it was normal and didn’t give it much thought until my wife made an appointment for me to go to Cenegenics for a consultation. After the lab results came back I was surprised to find out that I was borderline diabetic and my hormones weren’t at optimal levels. The doctors and nutritionist put me on a plan that got me back on track and now I feel better than ever! I really wish I had done this years ago! Thanks, guys!
I feel much better and have the energy
After trying other “wellness” places I felt like I was wasting my money. I was still slightly overweight, didn’t feel well and I was growing ever more frustrated because I knew that it shouldn’t be this way (Im 43 years old). In a last-ditch effort, a friend of mine recommended I go to Cenegenics® over in Manhattan. My first consultation was back in February and I’ve going there ever since. I feel much better and have the energy to keep up with my 11, 8 and 6 year olds. You won’t be disappointed.
Hands down, it's the best place I've ever used
I’ve lost 18 pounds and feel great! Now if they can only figure out a way to get rid of my gray………. Love you guys!
