The fact is his coke is probably not that pure. The only way you will receive 100% pure is if you know Pablo. Even the dudes buying kilos are receiving cut stuff. Then they stomp on it, and so on. Pure is only available in the countries that produce it and to select people very high up, and then those people only get the pure for their head stash. No one cares to sell pure because they know the fiends will buy it no matter what. By the time any of this coke makes it to Silk Road it has been stomped on many times. No one on Silk Road is moving kilos. No one cares. I don't believe their claims of percentages but it is still probably relatively pure for their step on the ladder.
