I'm heading there in a day or two also. A couple of people told me from this page that the regular pharmacies will carry vet juice. Last time I was there they had some, not Ttokkyo though, but it has been over a year since I've been there. The pharmacist actually showed me some of his fake gear that he sells to the not so smart ones. So pay attention. Good luck and shop around, you will find quite a difference in prices.
