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

Frequently Asked Questions

How do I reconstitute this peptide?
Add 1–2mL bacteriostatic water to the lyophilized vial by directing water down the inner wall of the vial. Swirl gently until the powder fully dissolves — do not shake or vortex. The solution should be clear and colourless. Use immediately or refrigerate at 2–8°C.
How should this peptide be stored?
Store lyophilized peptide vials at −20°C for long-term storage. Once reconstituted, store at 2–8°C (refrigerator) and use within 21–28 days. Avoid repeated freeze-thaw cycles, direct light, and heat exposure.
What purity is this QSC compound and how is it verified?
All QSC compounds are tested to ≥99% purity by HPLC peak area analysis on every production batch. Molecular identity is confirmed by mass spectrometry. A Certificate of Analysis (COA) is published on the product page and independently verifiable at verify.janoshik.com using the batch reference number.
