TestoGain and EstraMend

After taking the test, I ordered the EstraMend and TestoGain. I have to say that taking them together has greatly improved my strength and stamina, my outlook on life at age 54, and minimized my hot flashes almost 90%. Unbelievable. Estroven helped some but these two additional supplements truly lifted me up so that I actually feel younger and more put together now. I have referred friends to your website in hopes that they, too, will find relief. Thank you, Dr. Collins!

TestoGain in combination with Estroquench has made a dramatic difference for me. My doctor, after running extensive blood tests, recommended that I take these two products. They have contributed to renewed energy, a loss of 15 lbs (from 230 to 215) in roughly 6 weeks and significant reduction of my 'man-boobs'.
