So how much synthol have you used? Are you saying you've had scans of the body parts you've used them on and the doctors couldn't see anything abnormal?
at the time i had x ray done i had 3 inches on top of my natural size mostly in biceps, with mostly scar. I ve had xray done on the arm several times in a short period, they didnt see anything unusual, and when i looked at it it looked just like any other muscle seen in the image - shoulder, pec , forearm etc....the x ray wasn done to search for any growth or scaring....the only thing they comment when they saw my arms was if i m using steroids
