Dose - Bit of a noob question. dosage equivalency?

[ThusSpokeZarathustra]

Swim is wondering if there is an amphetamine dosage equivalency chart?
or if anyone knows what 130mg of caffeine would equate to in other amphetamines (damph, etc.)? I know they're molecularly different, and produce different effects, but swim is curious.

[Stephenwolf]

it would equate into no dose of amphetamine at all, 130 barely even causes affect for swim., some people believe that 400mg or more (caffeine) is kind of like an amph high in the weakest jittery nauseated sence, but if it caused any sensation at all similar to amphetamines it would be a 10mg dose MAYBE. really caffeine and amphets are quite strongly different in effect and in method of action to where your question would be like asking " Whats the equivelant dose of 2 shots of vodka for coffee?" its not equivelant at all.

[tryptamaster]

yea haha maybe like 2.5mg of amphetamine salt.max. haha yea, at 400mg swim compares it to MAYBE 5mg not even 10 like the other df member said. swim thinks this is more like trying to ask" how much ghb is 3 shots of vodka"

[fiveleggedrat]

Yeah, this is a silly question.

If Swiy needs to know this for theirself, test dose caffiene up to reaching the point they want/need.

Everyone is radically different, plus caffiene and amphetamine are different CLASSES of drugs, acting on completely different receptors.

[Stephenwolf]

Unknown had been highly sensitive to caffeine when originally dosed at 400 mg, and had a light tolerance when the 10mg amph was taken, regardless completely unrelated and equivelance is a silly thing to ask.

[cra$h]

but is there a chart between ephedrine, d-amp, meth, and even levamfetamine, etc?

[Stephenwolf]

best i could find, might be helpful... http://www.johnswank.com/Dosing%20an...Stimulants.htm


http://www.amphetamines.com/ephedrine/ information there might also be helpful,though not in chart form, it discusses the effective dose of several substances in mg/kg.

[ThusSpokeZarathustra]

SWiM was not suggesting that they were related substances, but was just curious what dosage of caffeine would produce a similar effect (obviously no euphoria, but other stimulant effects) to other stimulants.

Swim figured since amphetamines and caffeine are stimulants they may have similar STIMULANT properties.

btw: thanks for that first link Stephenwolf. I was curious where I could find one of those as well.

[Stephenwolf]

absurdly high doses of caffeine have been used for psychoactive stimulant effects, several reports are on erowid.org and i know of at least one person who used to use high dose (600mg) caffeine recreationally, though nothing like amphets, was still vaguely pleasant, again check erowid, or maybe use this sites search engine, something might turn up...
