as for the 4-dimethylaminorex, if your asking the price per Gram, per gram would be kind of expensive, since the average dose is 15mg. (and expensive to purchase wholesale). I can tell you that the prices wont be out of line. The nice thing about the amphetamine salt is that its pure white. the amphetamine that I see for sale in the market it is orange,(which means they didnt get all the impurities out).. and I question the claims on some of their adds. the 80 percent pure looks to be about 50 percent pure.. the amphetamine salt will be available shortly but the 4-dimethylaminorex will take some time (due to the cost)...
