PMAstimulanttentativeAn empathogen with a slow onset and very strong serotonin release. This, combined with its lack of dopamine release, often leads users to dose more for the pleasurable effects which never come, leading to hospitalisations and deaths. Sometimes mis-sold as MDMA.
PPAPstimulantnootropicStimulant of the Amphetamine class, with an odd effect profile, and MOA.
Prolintanestimulantresearch chemicaltentativehabit formingA stimulant drug which is a dopamine reuptake inhibitor, related to MDPV and Pyrovalerone. It was first developed in the 1950s, and has seen some light usage in rave culture, though it remains relatively uncommon. Believed to have a relatively forgiving safety profile.
Propylhexedrinestimulanthabit formingcommonA relatively common CNS stimulant sold over the counter in benzedrex inhalers.
Propylphenidatestimulantresearch chemicaltentativehabit formingPropylphenidate is a short acting stimulant.
PseudoephrinestimulantcommonWidely sold as a decongestant, and one isomer of Ephedrine. It is not generally considered to have any recreational value. Is also used in the synthesis of Methcathinone and Methamphetamine.
PV-8stimulantresearch chemicaltentativehabit formingStimulant of the pyrrolidinophenone class that is a higher homologue of α-PHP and generally less potent and less effective.
Pyrophenidonestimulantresearch chemicalhabit formingtentativeAn NDRI pyrovalerone derivative reported to have very similar subjective effects. Virtually no information exists about this drug's effects in humans.
RTI-111stimulantresearch chemicaltentativehabit formingStimulant of the Phenyltropane class that acts as a SNDRI. Presumably it will have a slightly slower onset and bit longer duration than its parent compound Cocaine. Yet being the Tropane analogue of 3,4-CTMP.
Sulbutiaminetentativestimulanthabit formingsupplementA thiamine derivative nootropic and stimulant drug. Caution should be used as Sulbutiamine reduces dopamine output over time with consistant usage.
TH-PVPtentativeresearch chemicalstimulanthabit formingA pyrovalerone stimulant related to α-PVP and Naphyrone. Very little information about effects or safety profile, virtually no evidence of human use.
TheacrinestimulantnootropicSmall alkaloid which can be seen as a structurally modified version of Caffeine, with similar stimulating effects. It also shares anti-inflammatory and analgesic effects with Caffeine.
Thiopropaminestimulanthabit formingresearch chemicalA substance that is closely related to Methiopopramine (MPA). Is roughly about 1/3rd the potency of Amphetamine, differs from amphetmine from the phenyl ring is switched with a thiophene ring.
Troparilstimulantresearch chemicaltentativehabit formingA stimulant and dopamine reuptake inhibitor developed in the 1970s, it is frequently used in scientific research but has seen little usage outside of the lab. Similar effects to Cocaine, though much longer and without any local anaesthetic action. Probably hard on the nose.
ViloxazinestimulanttentativeNRI that was used as an antidepressant in some European countries, and had a pronouced stimulant effect similar to amphetamines without any signs of dependence. Withdrawn in the early 2000s.
Vyvansestimulanthabit formingcommonAlso known as lisdexamphetamine, this drug is a CNS stimulant often prescribed for ADHD, narcolepsy and obesity. It is also a pro-drug for dextroamphetamine, and functions as a method for providing extended-release stimulation. It is sometimes prescribed alongside an SSRI for depression.
YERBA-MATEcommonstimulanthabit formingnootropicIs marketed for its ability to suppress appetite and burn fat. Yet only with high doses. It has a quite high ratio of Caffeine. It has anti-inflammatory properties.
α-PBPstimulantresearch chemicalhabit formingtentativeStimulant that is the homologue between α-PPP and α-PVP.
