To begin, TH-PVP (3′,4′-tetramethylene-α-Pyrrolidinovalerophenone hydrochloride) is an analytical reference standard that is classified as a cathinone. Physiological and toxicological properties of this compound have not been investigated. This product is intended for research and forensic applications.
TH-PVP / A-PHP / A-PVP is a powerful synthetic stimulant drug which functions as a norepinephrine-dpamine reuptake inhibitor (NDRI). Being roughly a quarter the potency of MDPV the effects are said to be comparable.
A-PVP, α-Pyrrolidinopentiophenone is an alkaloid in the pyrrolidine and ketone chemical classes. Functioning as a norepinephrine-dopamine reuptake inhibitor (NDRI) and acting as a stimulant on the central nervous system and cardiovascular system.
A-PVP was developed in the 1960 and has been available on the research chemical market for several years now. And is used as a recreational drug.

Very little data exists about the pharmacological properties, metabolism, and toxicity of 3-MMC, and it has little history of human usage. Firstly, 3-MMC became available on the online research chemical market, shortly after the banning of mephedrone. It is a prominent example of a contemporary designer drug specifically chosen to mimic and/or replace the functional and structural features of its recently-controlled predecessors.
In addition, 3-MMC, or 3-Methylmethcathinone, is a molecule of the substituted cathinone class. Cathinones are a sub-category of amphetamines, sharing share the core amphetamine structure of a phenyl ring bound to an amino (NH2) group through an ethyl chain and an additional methyl substitution at Rα.
3-MMC and other cathinones are differentiated by their ketone substitution on the beta carbon of the amphetamine skeleton, meaning they are β-keto-amphetamines. Also 3-MMC has two methyl substitutions on its cathinone skeleton, one at R3 of the phenyl ring, and a second at the nitrogen group RN.
and lastly, 3-MMC is analogous to mephedrone; it is identical in structure except for the placement of the methyl group at R3 instead of R4.
