Have you really thought this out?
Because what you're thinking of doing is a bad idea for numerous reasons.
1. It's illegal of course but at a much different level than simply getting caught with a few vials... and LE is hot on the tail of anyone who's importing powders/
GH/anabolics... just google Operation Raw Deal.
2. the chances of
now finding a legitimate powder source are about like the chances of finding Bin Laden. However the chances of someone like you without any connections, finding a powder source who either flat out rips you off or sends you powdered aspirin are very good.
I think your not having any connections is a fair assumption regardless of how long you're really been around, or not been around, because, no offense intended, but if you had any connections you wouldn't be asking such basic questions.
3. customs has gotten much better at intercepting anabolics and powders being imported into the States. Be prepared to take some losses as most Legitimate powder sources will no longer resend 100%. They would go out of business as there are simply too many confiscations nowadays. If they say they will beware of what you get, if anything.
4. Even if you could get ahold of
Legitimate anabolic powders, you've now got to order a highly accurate scale, oil, BA, BB, filters, flasks, melting point thermometer, vials, stoppers, caps and crimper. That's quite an investment if you do it anywhere near right. The crimper alone is almost $200 and a good scale is about that much plus everything else and before you know it, you're looking at about $800 before you've even bought a mg of powder. Of course you can always take a bunch of shortcuts... what the hell, you're only injecting some junk deep into your body.
5. Also, good luck finding companies to supply you with everything. Many "research" companies and other companies who supplied these things got visited after ORD and are either no longer in business or no longer offer these products or will only supply these products to bonafide businesses, not individuals.
6. And of course if you should happen to be the recipient of a controlled delivery, the charges against you are substantially more serious than simple possession for personal use.
7. So in my view, you're 100x's better off to simply go with a tried and proven source who's been around for a long time and has solid references for good customer service and a great product. Nowadays, that pretty much means someone international as almost all domestic sources are now in jail.
So do what you want but it's now a whole different world than it was a few years ago.
