Just FYI there are plenty of microdots being made somewhere; SR2.0 shows that. I have seen two different types, a red star and an orange dot (thicker than the ones I remember from my LSD days in the 70s), myself in the past year.
Not that I would touch them. Once you have kissed a God and known the secrets of life, the universe and everything ONCE there is no point in repeating the experience!
I hear that the average acid is now between 50 and 100mcg; what's the point? Back then they were at least 300mcg and more than likely closer to 500mcg, ten times the strength of what passes muster now. Nobody knows what a trip is any more! But I have heard that the RC LSZ is ten times as potent as LSD-25 and is readily available and totally legal...
