First off, a vaccum sealed package is shipping 101. This is standard practice when shipping items. If the package breaks open or the vial breaks, the contents will not spill all over the place.
For a guy who has such an elaborate setup and has such a large inventory or products, I'm shocked that he would just bubble wrap the vials. Anyone who has gotten any clandestine products in the mail expects a vacuum sealed package.
Secondly, it bothers me a bit when he says he just sold to a couple of his buddies, yet has such an impressive lab setup and inventory list. Look, plenty of guys here have home-brewed for personal use. What do we do? We get a bunch of sterile vials, BA, BB, and Whatman filters and spend a lot of time cooking and filtering. It's a bit odd to say that's your homebrew setup for personal use (and maybe a couple of friends). I can be wrong, but I sure wouldn't be spending tons of money and fabricating a lab to just to homebrew a few vials a month for personal use. Your setup was created purposefully for cranking out large amounts. You, obviously, have spent plenty of time getting ready to produce lots of vials for mass marketing. It's probably time to drop the line that you are just a home brew guy and just happened to decide to sell to hundreds and hundreds of people. This is an operation that's been coming for a long time.
Also, you have a full-time job, it seems. You made an earlier comment about a work BBQ. That's understandable, but at what point in time should we expect the "Sorry, guys. Life and work is just getting too busy. I can't respond or ship because of work. Sit tight." Like others have said, there are probably legions of lurkers on this board that never post. I can't imagine how many orders you've already gotten. I just don't think that someone who has a full-time job can pull an operation like this off. Forty hours a week and then brewing, shipping, packing, respopnding to emails, picking up funds? I don't see how that's really possible with the volume that you're getting and, if the products are legit, how you're going to keep up with that.
Being domestic, where exactly are you sending the powders off to in order to get tested? Aren't we all having a big problem, here in the States, with getting powders tested? Maybe I'm mistaken, but it seems like no one wants to test powders domestically because it's illegal. If it's done, it's an overseas company. So, I'm assuming the powders get ordered from China and then when you receive them, you send them off for mass spec overseas? Can we see any of the test results? I don't care about LabMax because we all know that it simply indicates that a hormone is in the solution...it doesn't indicate the potency or if any foreign particulate is in there.
Your response to the guy that orderd from you was extremely poor. This seems to indicate zero interest in keeping your customers, or yourself, safe. I'm no expert regarding USPS, but if they see a leaking vial and see a Tren vial, I would certainly bet that they will start watching - very closely - the place where you're doing your mail drops. So, you may not care much about customer's safety, but one would think you would care somewhat about your own safety.
