AS FOUND IN PINK PANTHERS, SPARKLE-E & GOGAINE First reported in the 1940s, methiopropamine became a big player on the legal high markets from circa 2010. Although it had fans in its own right, it was largely found as a primary ingredient of blends and brands, including Sparkle-E, Pink Panthers and GoGaine.
I personally found it to be too functional stand alone, but I consumed more than my fair share via the above combinations. Whilst having many pleasant experiences, I did have one nightmare, courtesy of GoGaine, during which I encountered the infamous shadow people. It wasn't fun.
Its popularity began to fade in 2015 when it was subjected to restrictions in the UK. However, I don't doubt that it is still widely available in some parts of the world. If encountered I would suggest taking it easy rather than going all-in.
