What is SZ352 Sleep & Calm Blend?

SZ352 Sleep & Calm Blend (Injectable GABAergic and sleep-promoting research compound) combines: GABA 100mg/mL (primary inhibitory CNS neurotransmitter), Histidine 100mg/mL (histamine precursor β€” histaminergic arousal system modulation), L-Theanine 50mg/mL (glutamate receptor modulator, alpha-wave promoter, anxiolytic), Taurine 100mg/mL (GABA-A agonist, inhibitory neuromodulator, osmoregulator), Melatonin 2mg/mL (MT1/MT2 sleep onset and circadian entrainment). Lidocaine 0.2% as local analgesic. The combined GABA-ergic, taurine, theanine, and melatonin activity creates a multi-mechanism CNS inhibitory research compound.

Research Applications

GABAergic CNS Inhibition Research

GABA + Taurine (GABA-A agonist) β€” combined GABAergic inhibition and sedation research

Melatonin Circadian Research

MT1/MT2 agonism with 2mg/mL dose β€” sleep onset, circadian phase, and sleep architecture

L-Theanine Anxiolytic Pharmacology

Alpha-wave EEG activity, glutamate modulation, and calming without sedation research

Histaminergic Sleep Modulation

Histidine β†’ histamine β†’ H1 receptor arousal system β€” modulation by inhibitory compound co-administration

Multi-Mechanism Sleep Research

GABA + Taurine + Theanine + Melatonin β€” simultaneous GABAergic, melatonergic, and anxiolytic activity
