This stuff is orders of magnitudes safer than street grade H. Since super H is made from pharmaceutical grade morphine you knock about 99% of the problems with H out of the equation. Street dealers cut H with all kinds of nasty shit to get a little extra kick, such as mephedrone and naltrexone, and these are only the educated dealers, the nasty ones, god knows what. Also H from natural sources can include botulism producing spores and other disease causing organisms. The difference between this stuff and normal H is a) this stuff is pharma grade which you will never see in your life and b) this stuff has 1 extra carbon molecule attached to the morphine. This extra carbon makes it more fat soluble so it hits you much easier and also your body takes longer to break it down so it lasts longer. this stuff is about 10-30x more potent than H on a weight by weight basis so obviously be careful. Its a real treat and those that trust this vendor will love it. Id like to repeat again that this is 90%+ purity, something you will not see in ANY other H on the silk road. Other than being more potent it is so much safer.
