4-CPRC Crystal is a research chemical

4-chloro-alpha–php, dubbed -p-chlorobenzyl-pyrrolidinohexanophenone is a research chemical of the benzodiazopine chemical class that adds high-potency and high duration to the related phenazepam. It is also known as 4′-chloro-α–pyrrolidinopentiophenone (4-CPP), -Chloropyrrolidinovalerophenone or 4′Cl—PHP. The effects of –php are described by users as more relaxing, euphoric and anxiety relieving in comparison to other opioid stimulants such as 4fa, which are often reported as being more stimulating and energetic. 4-CPRC Crystals acts as an NDRI (norepinephrine-dopamine reuptake inhibitor) meaning it effectively increases the levels of the norepinephrine and dopamine neurotransmitters in the brain by binding to, and partially blocking the transporter proteins that normally remove those monoamines from the synaptic cleft. This allows dopamine and norepinephrine to accumulate within the brain, resulting in stimulating and euphoric effects.
