check out health cabin for the real stuff make sure you upgrade to the EMS shipping so your not waiting a month. Don't buy their brand, stick with the dekang which is cheap and good. If you like ry4 than try USA mix its nice and if you have the money pop on over and get you some Boba's Bounty from AVE juice...its like heaven!!!!
I've ordered from Healthcabin using their standard mailing and never waited over a month to get my stuff, even just before one of their holidays...maybe I just got lucky tho. Their EMS cost is pretty steep IMO
