Okay, here is what you want. Stick with that for success, if you have questions, put them in the thread or write me a message.
you need:
Clear Household ammonia (put some in a clean jug, shake, if the bubbles stay for a while it has sope, use different brand)
Robinson Lighter fuel (the stuff in the yellow canister)
Your syrup (Use only with DXM ONLY)
Ziplock bags, Various container that u can seal, Glass baking dish
You do:
Pour Syrup in cannister. Fill syrup bottle with ammonia, dump it into same cannister. Now you got equa parts ammonia and syrup.
Close it and shake it. for about a minute, shake the hell out of it!
Now, add 1 / 10 robinson lighter fuel of the existing fluid. Calculation: If you have 250 ml syrup you should also have 250 ml ammonia in there. makes 500ml total. Now put in 50 ml of ligter fluid. Go with a tiny bit more just to be sure. Close, shake for a minute.
Here comes the tedious part... Pour it into ziplock bag, close it and pin one corner with a tack to the wall so that one corner is pointing down. Wait till the layers seperate, and then wait 10 minutes more. This can go verry fast or take up a whole day, that depends on your syrup. For me it always took about 40 minutes.
Now, what you want is the clear, top layer. Before you do anything keep the jug you used before for waste collection ready and the baking dish. Cut a tiny hole in the bottom corner and drain all the pink gunk. as soon as the clear layer comes out switch it to the baking dish so that all the lighter fluid goes into the dish. Carefull, rather waste a bit of the clear stuff than getting any of the gunk in the baking dish.
Use blowdryer to evaporate most of the naphta away. be sure that you don't blow a whole lot of shit in the dish though. when allmost everything is gone just let it sit and cool. eventually you end up with a gooey residue. Put the dish in the fridge untill it's cold and place it somewhere dry after that. Wait untill all the crystals are grown. Scrape them together and enjoy.
Take the powder in an empty pill, or wrap it in toiet paper and swallow it. hits you in 1 hour with no nausea or giving you the shits. Verry clean trip. You might still get an allergic reaction, crush up 2 benadryl and add them to your powder, and you got your mix ready 2 go.
The whole procedure took me 15 minutes, not counting seperation and crystalisation time
Stay safe, and if not sure about anything feel free to ask me. I've done enourmous batches of DXM with that method without any problems.
cheers,
