Before I did the real thing I was using 'Super=Pro 1' I think it was called. It worked real well ... and I didn't expect anything from it. In the years before that I had sworn off of everything OTC because I was scammed so many times along with most everyone else. I don't know what made me try it but it worked very well to my surprise. At the time it was a pre-mixed creme that came in a plastic pump bottle. Soon after that they quit selling it mixed and you bought the powder and transdermal creme and mixed it yourself.
Then they took all this stuff away and 'forced' you to go to the real deal - THANK YOU
I wasn't even aware you could still buy a transdermal test ... Hope you had the same good results with it I did if you do it.
