First thing's first: This guy is the real deal.
I ordered .5 g of the high purity stuff and it arrived in 3 or 4 business days. I don't have a scale handy so I can't say if it was over/under but in any case, I ate like 65% of it (spread out in two doses) and wow did it put me on my ass. The comeup was wicked smooth and after a while I was just fucking flying. After an awesome trip, the comedown was one of the smoothest I've ever had. Didn't even have a problem going to sleep at the end of the night.
Bottom line: Allchem has at least one new repeat customer and you should buy from him too.
I agree, he is AWESOME and his shit is the bomb.
