    Its is an often recited proverb, “If it sounds too good to be true, it probably is…” This is one fine counter example to such cliches. Based on the size of your purchase, you can included 1 – 3 FREE samples in your order. In my last order of 2-fdck I got samples of bmdp & ebk (1.5 grams each.) And I’m pleased to add that both free samples worked in the lab wonderfully proving efficiency and purity of both products. While both had similar stimulative/euphoric results during lab analysis, they were also quite distinct in characteristics of their individual profiles. Ultimately, both were regarded highly for quality and purity, leading to very successful initial tests in the lab. Hoping to see ebk restocked for purchasing. Meanwhile, bmdp provides our lab with new research opportunities we were previously unaware of. Finally, the shipping and service was fast (both in products received and in emails returned,) and after nearly 2 years of business with RCB, I am easily able to recommend them to any labs looking to do research with this class of novel compounds.
    Thanks RCB~
