I have been using Scivation XTEND for the best part of 10 years. I am 69 years of age and have been resistance trading on and off since I picked up my first barbell as a 15 year old school boy. A supplement back then was a peanut butter and honey sandwich. Since using the XTend my body shape as improved as I have become much leaner and defined. I know the Xtend is responsible as no matter how much I strove for "definition" over the years it just did not happen until about twelve months into the use of this, in my eyes, outstanding supplement
I still train regularly and I look better now than when I was 25. Unfortunately the Xtend has not helped the white hair or the wrinkles.
