d-threo-MPH (Focalin) is the main active isomer @ DAT>NET out of the 4 possible isomers in the original molecule
Ritalin (Methylphenidate) was brought to market containing only d/l- threo-MPH
-Taking Ritalin with a meal speeds/aids in absorption
-consuming ethanol/alcohol 30min before or after Methylphenidate increases the active d-threo-MPH (Focalin) by 40% and Significantly potentiates the euphoric pleasurable subjective effects in all study participants
Have a light fatty meal and ingest Ritalin IR 40mg in addition to a pleasurable Opioid you’re familiar with (Oxycodone 20/40/80mg IR or Dilaudid 8-32mg), followed by several Rum&Cokes 2-4oz of Spirits, onset in 30min, 1h near peak serum levels achieved and a 40% increase in active d-MPH = Dopaminergic Pleasure
Amphetamines are amazing, and yes, Ritalin is a “Classic Amphetamine”
Benzedrine (racemic)
Biphetamine/Adderall (mixed salts 75% D - 25% L)
Dexedrine (d-Amph)
Methedrine / Desoxyn (d-Meth)
Ritalin & Focalin
Phenmetrazine
Ritalin & Phenmetrazine are both Highly regarding classic Amphetamines
Dextro-Amphetamine (Dexedrine) is probably the most pleasurable & euphoric amphetamine, because getting a script for Desoxyn (d-Methamphetamine) is not too common, BUT happens here and there in the U.S.
