Wei Lab has ways to treat injuries using our FASTT and WHITEE patches, which would help with back pains and sport injuries. The patches are simple to use: just stick the patch on for two days and remove for a day and stick another patch on for another two days. Significant improvement is seen within the first week of treatment which is just three patches! If you have any questions and are in the Texas region, feel free to contact me at 888-919-1188 ext:117. My name is Spencer. You can go ahead and look at our website at weilab.com if you wanted more information.
