I'm assuming this guy is either dead or back in prison -in which case he is in chronic pain 24hr a day and wishing he was dead because they wont give him pain meds! I hope he's OK and nobody died as the result of the 500 too 1000 grams he made but that's a LOT of fentanyl -There are a lot of people rotting away with life sentences for a lot less!
With federal guidelines providing an inmate population flow guaranteed to keep a bunch of fuckheads in business forever -A few grams of fentanyl can get a guy with a couple prior drug offences a life sentence. Advertising that you are manufacturing something that is responsible for hundreds (maybe thousands) or deaths in the U.S. on a site crawling with rats posing as normal people is not the most brilliant thing a brilliant chemist can do. Although most of the deaths were caused by dumbshits who don't have an understanding of simple mathematics, the chemical was blamed.
Posting the years in prison, prior convictions and health issues I could probably find out this guys identity in a few hour -I imagine the thieves and whores at the DEA have people much smarter than me who could figure it out in a matter of minutes. You can be sure they were looking for the phenylacetaldehyde shipment from china after he advised them is was on it's way!
