I like methylphenidate quite a bit (tried it only few times orally) but summer I had ethylphenidate, quite a bit of it over 2 - 3 weeks, mostly snorting, it was great (well along with few other things but still), better than 2f-a, 2f-ma and one other fluoro amph (not 4f-a, didn't try that one so I think 3f-a), hell probably better than plain amphetamine (not meth though which I tried only a few times) as I'm in fact not a huge fan of stimulants (especially what you would call functional stims, even though 2f-a and 2f-ma were lighter they were a lot less edgy than plain amph which is good, as they don't make me really more functional, some other group of drugs are much more my preference for functional/work drugs). But on ethylphenidate I had a lot of fun and and there was nice synergy, for example with alcohol, not like with speed which kind of keeps you sober and it was not as nearly fiendish as coke so it was kind of perfect for a summertime fun. Wonder if 4f-mph might come in handy in a way ethyphenidate did….
