I've always thought the LD50 rates of amphetamines were kind of tricky to figure out, the amounts I see mentioned on a mg/per kg basis always seem kind of astronomical. I'm not sure if he'll be able to find a reference although I remember reading something like "fatal doses for children 200mg fatal dose for adults 1g" - but I can't remember what route of admin. that was and I don't think it was from a reliable source.
It's tricky to know how cut your meth is, even if you wash it there could be something that gets past the simple methods we use.
300mg of street meth IV isn't uncommon but it's really hard to compare it to Ethyl at this stage.
Well that's a relief

If you ask something like how much can you dissolve in .4ml of water people start to get a bit worried. I don't think you'll have any problems with solubility if you get it from a decent source, and don't try crazy doses.
Comparing a ritalin xr cap to ethylpheniadate powder/crystal is like apples and chimpanzees. A ritalin xr has heaps of fillers and binders as well as the extended release matrix as I'm sure you know. 50mg is a pretty small amount of material...but I'm pretty sure you realize this. Use scales if you can.
Just be careful dude this is still a relatively unknown substance compared to methamp. and methylphenidate.[/QUOTE
Yeah thanks that was the point i was trying to make. IMO the EP I have has some topical anesthetic properties. Perhaps I should have said 50mg meth 1st time CAN cause fatality. Plenty of research out there to support this. even good old pubmed has some relevant info. The issue is quality ie 50mg methamphet synthesised in a lab for Merc pharma is going to be considerably different to your average street meth.
