Iยm a regular cannabis user and drinker. Less often Iยll have coke and amphetemines. I have tried crack, heroin, mushrooms, lsd and a bunch of legal highs. When ethylphenidate was legal in the U.K. I developed quite a habit. For a few months I was taking about 1 gram a day from a couple of different online suppliers.

Summary
Ethylphenidate (also known as EPH) is a novel stimulant substance of the phenidate class that produces traditional stimulant effects when administered. It is a closely related analog of methylphenidate (brand names Ritalin, Concerta). The two substances have very similar pharmacological mechanisms but discernible differences in their subjective effects with ethylphenidate often considered to be recreational.

[Erowid Note: The dose described in this report is very high, potentially beyond Erowid's 'heavy' range, and could pose serious health risks or result in unwanted, extreme effects. Sometimes extremely high doses reported are errors rather than actual doses used.] This is a real beauty.
Trip report: Previous drug use added while still buzzing just incase it may help others or explain why I'm feeling such a rush to this relativity unheard of RC: Speed (but only UK speed, wet dabbed it and bombed it. Felt awake but never like this, feel awake AND happy.
ABBREVIATIONS USED: BST British Summer Time, UTC+01:00 MDMA 3,4-methylenedioxy-N-methylamphetamine (Ecstasy) 4-MMC 4-methylmethcathinone (Mephedrone) I found this substance mildly addictive (less addictive than 4-methylmethcathinone (4-MMC), though), as I had a (beatable) craving for more every ca. 30 to 45 minutes.
Ethylphenidate First Look I ordered this and a few other RCs from a reputable RC vendor in Canada, waiting for shipping was dreadful despite it taking under 24 hours for my order to be completed. I am extremely excited for this RC as I hope to use it for a function stimulant.
After years of reading various experience reports, I felt it was time to finally pass on information in the hopes somebody will find it useful. Since the age of 16 I've tried the usual: alcohol, cigarettes, marijuana etc.
Ethylphenidate-Like Substance Overdose [Erowid Note: The doses described in this report are potentially life threatening. The amount taken is beyond a heavy dose and could pose serious health risks or result in unwanted, extreme effects. Doses such as this have been known to cause hospitalizations and/or deaths.
40mg insufflated at around 8AM. Now I'm a relatively big guy and have tried many substances, always finding myself to be tolerant so thought nothing of taking such a large line. I had also heard that it was 4x weaker than (adderal) so figured it'd be fine.

Ethylphenidate 250mg + Methoipropamine 70mg - both IV - enjoyable it's been bette r Ethylphenidate 250mg +/- in staggered doses, Methioropamine 70mg +/- in 1 hit ROA Intravenous Experience: I have done a bit more than a gram of methiopropanine.
My first comment here is this stuff blows MDPV out of the water. I ain't saying it's the wheel, but it's certainly enjoyable. Physiological Data: 65kg male, early 30's, have tried and loved almost every drug I could get. *Some* experience with coke, crack and amphetamines. Smoker but relatively healthy.

Hi blue light forums! This is basically one of my first posts, snooped around the forums a lot of information for a good ride! Male, personality INTP,(think this is kinda useful information for trip reports) hmm 20 years old! (had to think about it for a second) 14 stone ish! probably closer too 15 touching over 6 ft s...
Introduction: I don't have scales unfortunately, so this was all eyeballed. I'm about 175cm tall, 52-55kg and not much muscle or fat so stims tend to hit me harder then others. I had consumed a cup of coffee prior to ingestion, and smoked cigarettes before, during and afterwards.
Ethylphenidate IVd - ~75mg in separated doses - Experienced - 1st time trying EPH Hi all! First of all this is a copy-paste of a trip report I posted in another forum before, I don't know why I did it first in the other one, maybe because I found a lot of TR in one single thread and I wanted to share mine.
(Ethylphenidate/Multiple doses) First time: "Oh me likey!!" Intro: This is my first experience with Ethylphenidate. My experience with other stimulants or alike is fairly high.
