differentiate between what is being prescribed and itās street analogs, while hurling terms such as dextroMETHamphetamine, levomethamphetamine. while not even mentioning that methamphetamine converts into dextroamphetamine.Moving forward -neurotoxicity. Agree- it can be, and is neurotoxic, but why? At which doses?Coming onto end and of that bird excrement of a first paragraph author states that , agdextroMETHamphetamine is more potent than levoMETHamphetamine. anyone who is closely related to a topic of stimulants would be just saying that amphetamineās right molecule- dextroamphetamine promotes better stimulation of a CNS, and itās useless left molecule-levoamphetamine mostly responsible for not desired overstimulation of the peripheral system-as in you sweating.Now, comparing something like methamphetamine and adderall in their effectivity... who reviewed all of this? Why the very first paragraph doesnāt clearly distinguishes between
Desoxyn, a hydrochloride form of methamphetamine, approved by the FDA as a last line of treatment of ADHD l, morbid obesity and severe forms of narcolepsy, and crystal methamphetamine.where are specifics? All of that comes out being biased to say the leas. While Desoxyn is most definitely not being prescribed often, it saved a lot of lives. It is authors like you, who made it even more harder to get.

Now unless there is some proven pathway that makes methamphetamine roughly 10x more potent in terms of its potential lethality (assuming the average adult weights 80kg), then we should probably remove this until we can verify it with more research, I've tried to access the full article that the 200mg

Additionally, source is unrelated to this sentence - it measures whether the caudate-putamen dopamine response after deprenyl administration can be attributed exclusively to its metabolite L-meth, or also to L-meth metabolites and/or deprenyl itself.
599:
Comparing D-amph to L-meth here is odd, because no reason has been introduced to suddenly compare an enantiomer of amphetamine to an enantiomer of METHamphetamine. There is also no source given. It should probably be dextro*METH*amphetamine.
