I’ve had a few successful transactions online. General guide lines in my book for ordering internationally:
The hardest part is finding a legit source. None will be registered (website that is) in the US. Also, watch out for sites that have adverts all over them. BIG red flag. They’re a site selling OTC supps with “roid like” names if you see that shit. Most legit sources, if they have a site, will have a very clean, and a secure site requiring you to sign up for a secure username/password login.
If you do not already have one, get a secure, encrypted email account with safe-mail.net, cyber rights, securenym, etc. Avoid hushmail. Many sources will not communicate with you with a ‘commercial’ account like AOL, yahoo, etc.
I have a legit sounding false name. “James Smith” for example. I use that name for my Western Union, and “Ship To”. Unless you send over $999 you don’t need to show ID, so no need to be all shifty eyed and nervous when the high school kid is wiring your money. Most WU “clerks” are kids.
Make sure before you leave, all info was entered accurately. From my experience, a legit overseas source will not require a “test question and answer” on the WU info form. That’s just one more potential area for a big eff up. If the kid happens to ask a stupid question about whoever you’re wiring money to, tell him/her it’s not really theyre business, but you friend, or cousin in Pakistan (for example) needed some money. I doubt they’ll ask anyway.
Most international sources seem to also have three main shipment options. Registered Air, Unregistered Air, and Registered Express. If you want a higher chance of getting your order, avoid Registered Express. With all the b.s. going on right now…an American getting an order from Asia, or wherever with extra “rush” shipping on the package raises red flags. Also, keep in mind you will need to SIGN for whatever you order if you choose Registered Express, or Registered Air. I don’t like having to sign.
That’s an acknowledgment on my part that I did indeed order what’s in the package. If it’s just left in my mailbox, it was just left in my mailbox. Wrong deliveries happen every day. 
I’ve not had an issue getting what I’ve ordered using Unregistered Air.
Most sources also break up your order into small packages. From my experience so far, they are small, non descript packages. My last order for example, I got the first part in 2 weeks, and the rest came 2 weeks later.
I also order ONLY what I need. A cycle or two at a time. Since I only do a couple cycles a year, I only need to order about once a year. Just makes sense for “James Smith” in USA to only have a friend from overseas sending him something once a year or so vs every few months or more.
If you’re fortunate enough to stumble onto a legit DOMESTIC source (from within the U.S.) God Bless you. I don’t know of any. There supposedly are still many out there, but they most likely do not have a site, and operate on a secure email/list only basis.
Don’t PM me asking for sources either. I’ve worked hard enough to find mine, and lost $$ in the process. That’s up to you to find your own. It’s a ‘right of passage’ per se. Good luck, stay safe!
