MDPHP (3′,4′-Methylenedioxy-α-pyrrolidinohexiophenone) Crystals – High-Purity Research Chemical – 1g / 5g / 10g Packs – UK Next-Day Discreet Delivery
MDPHP, also known as 3′,4′-Methylenedioxy-α-pyrrolidinohexiophenone or “monkey dust” in street nomenclature, is a potent synthetic cathinone and novel psychoactive substance (NPS) belonging to the pyrovalerone family. This research chemical is structurally related to MDPV, α-PVP, and α-PHP, featuring the characteristic 3,4-methylenedioxy ring fused to a longer hexanophenone chain with a pyrrolidine ring. At ukmushroomsok.com we supply laboratory-grade MDPHP in pure crystalline form (>98% purity confirmed by third-party HPLC/MS analysis), appearing as large, translucent-to-opaque white/off-white crystals or shards with a characteristic mild chemical odour.
MDPHP is one of the most powerful and longest-lasting stimulants in the current NPS cathinone landscape. Researchers and private individuals in the UK report extremely strong monoamine reuptake inhibition (primarily dopamine and norepinephrine, with significant serotonin activity), producing intense euphoria, hyperfocus, extreme motivation, wakefulness, elevated heart rate, vasoconstriction, and compulsive redosing behaviour. Duration is notably extended compared to shorter-chain analogs: onset within 5–15 minutes (insufflated/vaped), peak effects 1–3 hours, total duration 8–16+ hours, with residual stimulation frequently lasting into the following day. The compound is renowned for producing an exceptionally “fiendish” profile – overwhelming desire to redose, tunnel vision on tasks, music enhancement, sexual arousal amplification, and a very high abuse liability even at low doses.
