Testoryl so say a superficial lying on the lips or superficial line in the nasolabial fold you almost kind of see the needle a little bit through the skin but when you're doing it in the penis doing a little bit deeper and it's actually pretty amazing you the pain of just slides right under that layer and it's a nice open layer where you can put the cannula there are some issues and for instance of a guy's circumcised versus not circumcised so if you're circumcised it gives you a nice end point of where the filler is going to go but also that skin is scarred down so it doesn't expand as much right right but between the glans the end of the penis and the shaft of the penis so sometimes you can get a little gap where they didn't expand as much because the filler can't go in there sometimes secondarily up their next visit we can go in there
