Your kit did the job again. I personally used one of your kits for a calf injury earlier in the year and was back competing in about 10 days vs. 6 weeks with the same injury 2 years ago. The hamstring kit I purchased for a teammate of mine who indicated he strained / pulled his hamstring 10 days before he needed run the 2nd leg on our 4×100 relay. Not only did he run pain free on our relay, he won the 100 meters 40-44 age group at the Penn relays. Thanks for your continued help.
