I'm gonna use my first post here to set a couple people straight.
Meth speed base ice crystal etc, is one of the worst drugs for speculation, every second person you speak to knows its "ketone this, pesudo that". etc, rarely is any of it true or spoken with any true knowledge on the subject, just like the "95% percent pure columbian cocaine" that your mums dads brothers aunties boyfriend gets.......
Firstly without getting into syths and things of that nature, amphetamine in australia is usually methamphetamine, because the common sythesis most people use to cook it relates to the use of pseudoephedrine and not ephedrine and with this particular reaction the end result is (meth)amphetamine, it would actually take further reductions to create straight amphetamine, hence why a massive percentage of the speed here is meth not straight amphet.
Now onto base etc, meth base is infact a clear(ish) oil. The gluggy speed you get is NOT base. Methamphetamine sulphate is hygroscopic which means it readily absorbs water from the air, resulting in the 'gluggy' speed that you receive, cutters like glucose make this worse and make the speed even gluggier because of the water, and from other left over sources of moisture such as acetone wash.
Lastly Ice is NOT technically methamphetamine. Ice has become a slang media term for crystal methamphetamine, which is in actual fact not true 'ice'. Proper ice was around a fair bit in the 90's from asia, and has been in asia for a long time. This particular substance is called 4-MAR or 4methyl-aminorex, and gives a bit more of a euphoric charge when smoked, a bit more like mdma than amphetamine, very tasty stuff indeed if you can find it.
Hope ive cleared up some stuff for some people
