No one finds one safer than the other? Obviously, overseas has to go through customs, but if the order isn't too big they'll just confiscate it. Domestic is less likely to be stopped, but if they bust a domestic source, your info is right there for the feds to find. That's not likely to be the case with some UG or remailer in thailand.
Delivery time SHOULD be faster domestic, though that isn't always the case.
Price is comparable, though a slight advantage to overseas.
UG labs are probably better domestic, though most Intel is pharm grade resold.
IMO, advantage goes to..... OVERSEAS.
Just NEVER EVER, EVER, buy so much that it even remotely looks like you have intention to sell, either way. And never do -- not even to a friend.
Stay safe brothers.
