I have had white once, I think the vendor called it white elephant, the particular strain I was unable to get it down. Too bitter or something just made have to vomit right away almost. Not sure how you take but I dump a scoopful in my mouth then swish and swallow with some grapefruit juice. Three scoops. Nasty everytime. Haven’t tried any extract I don't think. Mostly reds and some greens. Every weekday before work and maybe not any over the weekend, depends. I can definitely tell if I miss but nothing like withdraw symptoms or anything serious. Kinda like missing your morning coffee, just feel off and little less alert maybe but can tell it’s missing.
