It can be used as compression. I'm using it at the moment to nurse/recover from a hamstring pull and elbow tendonitis.
You apply it in the flexed position so when relaxed the tape pulls the skin away from the muscle allowing more blood flow. Stays on me for about 3 days before pealing off.
Rock Sauce, their version of bengay/icy-hot is the SHIT! Strong as hell and really warms up the area. I put it on my elbow just now and it got my eyes to water.
There is a cheaper brand you can buy. I think mueller makes it. I have used it for my knee cap tracking issue. I find athletic tape does the job though
Just want to let you all know i got my KT tape today. did both needs L shoulder and L scapula for stabilizing the shoulder. I did legs and no pain in my knees it was great. shoulder still hurts but it really worked on my knees
