groundhog, it sounds like it could be very basic, if your ph test range is 4-7 and it showed a 7. i might order some ph paper myself and see. the ph of the water was probably very close to 7, even tap water.
i'm also not as educated as i'd like to be (yet). i have no idea what properties other than ph could cause the irritant effect other than blade-like crystals.?
i'm not sure but i think there's a hcl form available and another that's not specified as an hcl salt... not sure if they're the same, but i think that in hcl form it would probably be acidic in solution? because of the hydrogen ions
maybe i should go back and read about the acetone wash i glanced over, i'm curious about that. however if the chemical is supposed to be 98-99% pure... it must be some seriously strong adulterant that's being washed out if that's an effective method. otherwise perhaps it's a chemical reaction with the ethylphenidate itself that causing the result.
other than that, i might try to get pure methanol (not sure how easy that would be) and just dump some of the ethylphenidate in there, let it evaporate, and try to judge if it might have been converted into methylphenidate based on maybe ph test and its effects, dosage differences... but there's also the complication of not knowing the isomer ratio or which of them if not both might be converted.
i would be Very hesitant to inhale this stuff... i really don't want to get emphysema
also i'm thinking that maybe insufflation would be more responsible than swallowing it, because i think that a deviated septum would be a hell of a lot better to deal with than something like crohn's disease. not sure how likely that is to happen, especially with lots of water, and ph correction if that turns out to seem like it might be helpful
with the thing about coadministration of alcohol and racemic methylphenidate resulting in ethylphenidate formation, i am not aware of the ethylphenidate in those instances being known to cause any problems except being hard on the liver (not sure)... and hopefully if there's liver damage from that it wouldn't be caused by ethylphenidate that's not being converted within the body.
kind of a headache but this is interesting
I did try a test on the water aswell to check if that could interfere with the EPD test and the pH was alkaline, 7.0.
But as I used a higher ratio of EPD to the amount of water, I thought that if the EPD was significantly acidic then it would at least show to some extent, a lower pH level than what the reading the water only test had shown.
Just to add I performed the test with the powder EPD not the crystal. The crystal is definitely more caustic than the powder I think, and not because the crystal is more abrasive due to the sharper edges of its structure, but the powder is still very caustic too.
If you put the crystal under your tounge, sublingually it burnt the flesh, visibly. The powder if you sublingual also burns but to a much lesser degree.
I don't think any of the washes that are described in this thread can cause it to be anymore less caustic to be honest, I've had a play about with them and it didn't really make much difference, I could of performed the washes with a bit more effort and time so there may be a way to gain a more successful result but I don't think there is a large enough impurity to wash out. The physical appearance of the powder and crystal look very clean, I know you can't rely on just how it looks to verify the purity but I would assume there would be some apparent evidence even if only slightly. The powder is brilliant white, very fine and consistent in density throughout. I would also think there would be a detectable chemical odour from any impure residue in it but it doesn't really smell at all. The smell from a small bag of chinese
4-MMC was very potent in pre-ban days and I'm sure that was because it wasn't getting washed thoroughly after synthesis.
Insufflating this stuff is definitely not the more responsible ROA over oral. I insufflated for quite a while in the beginning and ignored the burn and continued doing it until the pain was so intense I shone a torch up my nostrils and I nearly leapt from the mirror in complete shock. My nose has been well aquainted to things that shouldn't be going up there over the years but I had never seen anything like this. It wasn't a bit red and sore, the entire length of my septum was chemical burnt all the way up to the inside nasal cavity. Green and yellow burns that looked like it was nearly exposing the cartilidge under what should have been the nasal lining tissue. It looked as if hydrochloric acid had been having a party up there. Seriously. I always blew out a lump which can identify as to wether it was flesh or whatever congealment it might be.
Thats when I started orally. The only way if you are going to use it. I can get nausesous and do, but the nasal damage is just not worth even considering IME.
I also have inhaled it, I have vapourised it and smoked directly through a bong, which i'll tell you caused the acrylic to perish and crack and left the most vile filth of residue I have seen. I have also never inhaled something so harsh as the vapour from that. Might be good to mention now that I do try to be responsible but do tend to push the limits at times and I smoked up to 500mg several times and to be honest I don't know how my lungs and throat survived after what it did to the acrylic of the bong.
I agree that the ethylphenidate that has been converted in the body from metabolising alcohol and methylphenidate, is not the same as if it had been chemically synthesised.
Let me know how you get on with any experiments you carry out with it.
