Actually guaifenesin tends to create a third layer of separation when doing Agent Lemon. It's harder to get all the DXM out and you end up with a far less pure product.
lemonboy Reviewed by lemonboy on . DXM question ok i got some robotussin DM and iw as looking around and found that http://www.dextromethorphan.ws/robitussin-extraction.htm says that the Guaifenesin sticks to the amonia, i was wondering maybe if u use the DM with the ammonia to just extract the Guaifenesin, if it would b safe to still take the dxm product left over. i dont care if anything else stays i just want the Guaifenesin out...also is there any possible way tp get rid of the dxm after effect of stomach being upset each time i eat.
