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 — 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) — combined GABAergic inhibition and sedation research
Melatonin Circadian Research
MT1/MT2 agonism with 2mg/mL dose — 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 → histamine → H1 receptor arousal system — modulation by inhibitory compound co-administration
Multi-Mechanism Sleep Research
GABA + Taurine + Theanine + Melatonin — simultaneous GABAergic, melatonergic, and anxiolytic activity
