If what Strango said is true about not changing his filter, than every one of his products should come back as being more than one compound. And not changing your filter each time you brew a new compound is not very wise. Any honest source who does things the proper way should always change their filter. Ofcourse he just made that up to cover his ass for getting caught cuttin his gear. "Why did my primo test out as eq??? Ohhh ahhhh ummm ahhh ohh its cuz I just made a huge batch of eq...ya..ya umm thats it"
