Well I will give my latest uses w propane. I formulated a very small amount of co-solvent totaling about 3% overall weight, not mole. It wasn't nasty. It wasn't the tastiest. It was good consistancy and the high was definately there. Looked good felt good, so in small amounts, the shit was no where poo smelling, but wasn't as good due to the taste being off a bit. Not bad though. There's a way to get mercs out. Look in to propane explosions, there had been incidents where the soil, concrete, or other types of filtration that rendered it undetectable to smell. W that said, let's find a cheap solution. Squidworthless, to let you know who I am, I fathered CO2 METHODS and you sir are so far behind its not even funny, unless your me looking @ you!!! Make something of yourself w your infinate opinionated how co2 extractions aren't done. So how do I recover desired compounds of interest using carbon dioxide in scfe or cosub2? Yes and you think scfe is more potent than sub, I know you have know expirience in smoking the stuff nor hands on extracting w it. Such a late bloomer.
