In the field of biochemistry, this is virtually meaningless. A single substitution group is capable of producing wild changes in pharmacokinetics. The left and right-handed enantiomers of these molecules don't even act the same way in the body, and these aren't even positional isomers. The similarities with AMP and MAMP begin and end with being TAAR1 agonists. Off the top of my head, MAMP is also a potent agonist for sigma 1 & 2 receptors, and is generally more promiscuous.
Methamphetamine is a substituted amphetamine, not a "derivative". They're both simple substituted phenylethylamines, another TAAR1 agonist that is extremely prolific in your neurochemistry as we speak, and an incredibly diverse family of monoamines that range from lethal neurotoxin to serotonergic hallucinogen. The difference between the two is often as simple as a single atom moved 2 or 3 substitution points over. When you lack basic domain knowledge, please don't call other people dumb as you try (and fail) to correct them.
Amphetamines and methamphetamine are closely related drugs, as methamphetamine is a type of amphetamine. They both work in a similar way by increasing the release and blocking the reuptake of certain neurotransmitters, such as dopamine, norepinephrine, and serotonin, in the brain. As a result, they both have similar effect.
All you're doing is microdosing a terrible drug and calling it treatment. Addicts defend this, not logical healthy people.
> Methamphetamine is not a substitution for amphetamine.
I did not say it was a "substitution" which means something entirely different in this context, I said it was a substituted amphetamine. The rest of this comment reads like boilerplate drivel that completely ignores everything I actually wrote.
So are ethanol (vodka) and methanol (poisonous fuel). The difference is exactly the same - one methyl group (CH3).
If you think that it's a small difference, try drinking methanol instead of alcohol, and see for yourself.
(Or, rather, not see for yourself, given the side effects of methanol poisoning).
This is the bottom line. It’s a drug, it’s not good for you. That euphoria is not treatment, your being drugged. Only addicts defend long term use
So - you're wrong. And with that stupid insult you added at the end, you look even dumber.
