I don't think 250mg would be anywhere near a Lethal Dose, I'm no doctor just speaking from personal experience. First time I had MDMA I would've had around 200mg straight up with another 300 throughout the night. This was not healthy nor safe, but I was trusting my mate who advised me to double drop. It can be very intense high doses but the euphoria was amazing. I'm not advising anybody does the same thing first time, whenever I have friends try for the first time I make sure they have a low dose.
But I would be surprised of 250mg being lethal to anyone (provided they aren't allergic). But tread carefully if you decide to do this, do more reading, check erowid for some high initial dose stories and keep track of how much water you take. Drink plenty but not too much. Be careful, but also there is probably no need to start with such a high dose, starting with over 250mg is unlikely to be that much better then starting with 180-200 but it would risks are much higher. Just because I don't think taking 250mg would be a lethal dose does not mean that it wouldn't be harmful in some way.
Not trying to big note myself or show off or anything but I agree totally with TS.
My standard dose is usually 200mg when I get MDMA crystal. I find anything under that (still works) doesn't get me to the place I want to be. Between 100-180mg gives me a high but its sort of more in the background and short lived like only for an hour. Even after taking a 7 year break and getting back on it, I had a mate that had a lot of money to piss up the wall so he bought a lot of MDMA and I would just get that off him and after just a couple of times I found my tolerance shit straight back up as tho I never had that long break. These days I try to go a couple of months off it every few months kinda like a mine worker shift lol.
I just find that 200mg gives me the high that is reminecent of when I was in my hay day.
It sucks cos I only get 5 doses out of a gram so it makes for an expensive time.
I also find drinking alcohol changes the high. I wonder if drinking alcohol and taking MDMA changes the MDMA into another substance like when you drink on coke or dxm?
I know that when I was younger I never used to drink on mdma and MDMA used to hit me within 20-30 minutes, no gradual come up after an hour- 1.5 hours then be at peak but 20-30 minutes and you would go from clammy hands to full peak. Within an hour I was fucked but that maybe due to motabulism being fucked from getting older and drug use when I was younger.
Although I have worked my way up to the 200mg so it's comfortable.
I have done doses upto 450mg and I have written it in this thread before and that fucked me royally.
You look like a spastic, you feel like a spastic and people either come up to you hounding you for what your on or they look ar you strange and try to bypass your direction.
Not to mention as you start comin down you get a splitting fucking headache which nothing is going to fix.
Not a good idea when your listening to that relentless electro circa bloody beetroots style if shit. Fuck I hate that music hahaha.
