Yeah as it happens I had 5mg this afternoon at 2pm. thus the rather long post

(Are you in academia, that wink makes me wonder if you've papers published yourself, im just a ugrad. oops. Don't take offense anyway, I tend to write replies like that on bl as if they are directed to everyone and anyone who might be reading it, and some stimulants make me more patronising than usual).
I'm only just about calmed down now nearly 12 hours later, and had to take a pretty hefty benzo dose just now to be confident ill actually sleep.
It feels much like ethyphenidate in the subjective mental effects, that unique sort of driven focus that can sometimes turn into spending hours completely absorbed in your work. It's been so long since I had MDPV that I can't really compare the two but it's certainly longer lasting, while not being as fiendishly compulsive to redose (likely due to just how obviously potent and persistent it is, it also seems to develop much more smoothly over a few hours whereas MDPV would give me that instant rush which made it more difficult to avoid spending days doing small bumps every 30 mins). It leaves methylphenidate in the dust anyway with its meagre duration.
3,4-dichloromethylphenidate, ethylphenidate and mdpv all seem equally as capable of putting me into a state of hypervigilance, repetitive compulsive anxiety behaviours, pervasive general anxiety and unease, losing ability to focus on one thing because im thinking of 100 different things i need to do / want to do at the same time and end up doing nothing but getting more anxious about the fact im getting none of these things done, which just leaves me completely disfunctional and increasingly pissed off and agitated as the hours go by until the whole day has eventually disappeared and my deadlines are long gone.
I'm sure there is great potential for panic attacks and paranoid psychotic states to develop in people who take too much, too often and let it get the better of them. I'm pretty familiar with those extreme states and know what the early warning signs are, but even the strongest willed people with the most insight and lucidty under the influence of drugs should be careful with this stuff. Even earlier today I found myself going downstairs to see if the mail had been delivered every 10 minutes, then every 5 minutes, then I realised I'd been doing it for 3 hours and started telling myself each time i got up to check it 'thats a compulsive irrational behaviour which is just making you anxious and distracting you from your work and it will get worse, so stop doing it now and dont worry'. I still kept doing it anyway until the post came.
I rarely do stims these days so im fairly aware usually of how my behaviour changes like that, but i'd soon loose the insight if i kept dosing it for days without sleeping, or too many days in a row. Definately a drug that will cause people problems if it finds its way into the hands of reckless or vulnerable people, regardless of any longer term potential biological toxicity that might come to light.
ethyphenidate feels extremely physically unhealthy to me, and had some quite frightening cardiovascular effects on me even with conservative doses. mdpv at least is more likely to make you psychotic before you can take enough for it to be physically dangerous in a healthy person.
3,4-DCMP feels like it should be treated with a similar degree of caution and respect as desoxypipradrol requires, although it is more fun than desoxypipradrol I think, while not being as hedonistic as mdpv. I wouldn't take it after lunchtime if I wanted to have a couple of hours to chill out before going to bed at a normal time later that evening, it's not great having to resort to benzos to put the brakes on for bed, and I don't do all nighters anymore, as tempting as it is to keep going heh.
Every time each of us takes a new drug (be it novel RC or not) you are essentially rolling a many sided die. In this case, consider Viagra - a drug known to have some pretty notable but rareish side-effects. Blindness, for instance. But peeps are happy enough to roll that die for a boner!
sure, but new drugs introduced on the legitemate pharmaceutical market have gone through years of animal and human trials and have already been given to thousands of humans in stage 3 trials before they reach the general public (which is even then still heavily monitored and considered part of the aprroval process) Even then, rare adverse reactions may occur in some people,long term unanticipated effects might come to light affecting large numbers of people years down the line, the bottom line is the whole business of drug design and use in humans is a seriously risky process despite the most intensive oversight of the whole process. We all know how the profit factor has consistently led to corruption in the biggest pharma companys, despite their products being for the healthcare market.
Now the situtation is one of people solely motivated by money, with no regulation or oversight or quality assurance, putting drugs on the market as recreational, sold to rapidly increasing numbers of people all over the world who are completely uninformed and vulnerable - if taking drugs are a gamble then the regulated pharma market involves significantly less risk.
Some vendors are of course more reponsible than others, but it is extremely distasteful to see the thin veneer of respectability and responsibility some of them attempt to cover their business with, misleading customers by giving them the impression their products are 'pure' and publishing completely worthless 'product analysis' data on their site makes them even more dangerous than the sites selling mystery powders with made up names.
