Boca Bitch: Actually you're figures are rather low.
(from PDR 1998's amphetamine
Individual patient response to amphetamines varies widely. While toxic symptoms occasionally occur as an idiosyncracy at dosages as low as 2mg, they are rare with doses of less than 15mg; 30mg can produce severe reactions, yet doses of 400 to 500mg are not necessarily fatal. In rats, the oral LD50 of dextroamphetamine sulfate is 96.8 mg/kg.
from the MSDS sheet
ORL-HMN TDLO 41 mg kg-1
ORL-RAT LD50 55 mg kg-1
IPR-RAT LD50 125 mg kg-1
ORL-MUS LD50 24 mg kg-1
IVN-MUS LD50 68 mg kg-1
ORL-DOG LD50 23 mg kg-1
Dr. Rodger C. Smith found cases of people mainlining 15,000 mg of speed, that's 15 grams of the stuff, these were isolated cases and in no way representative of sane doses. He does state that most people can withstand direct injections of 400-500 mg, even if they never took the drug
Not that taking more then 60mg doesn't produce some level of discomfort in most folks. Nobody has to say "working up to 300mg" sounds like a fantastic way to become an addict
. Frankly they'd place good money you won't be able to quit after you do that. That sort of tolerance takes habitual addiction
. You ever meet a speed addict? They get obnoxious. That stuff will change your personality, it will change your relationships, and it will change your chemistry. You should consider going and reading up in the addictions forums to get an idea of what you are getting your self into. Scientists need to fund their experiments, you've your hands on some fancy grant? What happens if the supply of the chemical dries up? Can you deal with the withdrawal
when the time comes?
Experiments such as this have their uses, but one always needs to question their motives and compare them to the risks. You must take account external factors such as money, relationships, living situation. Failure to do so may lead to abject poverty or even an untimely demise.
What kind of shape is your heart in? Nobody's done some pretty massive caffeine
doses and knows how that feels, mixing with large amounts of amphetamines may push your heart to it's limit. Such a reaction is likely to be fatal, the cost of bringing you back to life can be incredible, ten's of thousands of dollars. It might behoove the scientist to attempt to find an EKG of some sort and learn how to read it.
Well best of luck.
