In 2004, running sprints with my sons track team, I pull a hamstring muscle. In 2009, I started doing sprint triathlons and re-agrivated it. I couldn’t get it healed through the 2009 or 2010 season. In the winter of 2010, I found QiVantage on the internet. I had tried every other pain relief product, (Ben Gay, Icy Hot, Ibuprofen, Blue Goo, and pain patches) nothing healed the hamstring. Within a week of trying the recovery series, especially the wrap, the injury was gone. Here it is late March, I just finished running a 80 min workout getting ready for a 1/2 IM.
