is there a differnece in the quality of the boost pill weather its from ultimate racing or ams performance or any of those other companies or there all the same ****????????

 

Its not about the quality, its about the the inner diameter dimension. It is theorized, but no substantial proof exists, that the GST, AMS, and UR boost pills are the same. Until someone actually measures all three with a highly precise device, there will always be some doubt.
