Extracting DXM from Triple C's is easy. All you do is get around 40 C's and crush them into a very fine powder, then let the powder sit in cold water for about 2 hours or so and filter the water from the powder thats left. DXM isn't water soluible and the other stuff in C's is, therefore after soaking the crushed pills in water, the powder thats left is pure DXM. And the robo cough gels which have 20 in a bottle and a total of 300 mg of DXM. I usually only use those to keep my high going, I like just down a bottle of syrup and get a thing of pills to take 2 or 3 periodicly while I'm tripping.
