A buddy of mine got some and couldn't handle it. He gave it to me to try. I was putting it in my side delts. The shit hurts like hell. Imagine the worst muscle soreness you've ever had, now think of it being constant for however long you use the synthol. I wasn't using very much at all, but I could barely lift my arms. You have to use a good bit for it to make a noticeable difference and it was gone within a week of stopping it.

Not worth the pain and hastle!
