What is RP226 Relaxation PM?
RP226 Relaxation PM (Injectable sleep and recovery blend) combines: GABA 100mg/mL (gamma-aminobutyric acid — primary inhibitory CNS neurotransmitter), Melatonin 1mg/mL (pineal hormone regulating circadian rhythm and sleep onset), L-Arginine 100mg/mL (nitric oxide precursor, growth hormone secretagogue — supports overnight recovery), L-Glutamine 25mg/mL (conditionally essential amino acid — gut integrity, immune support, protein synthesis during sleep). Injectable delivery provides direct systemic availability, bypassing the GI tract for CNS-targeted sleep and recovery research.
Research Applications
GABA-Mediated CNS Inhibition
Exogenous GABA — GABAergic inhibitory signalling and sedation/relaxation research
Melatonin / Circadian Rhythm
MT1/MT2 receptor agonism — sleep onset, circadian entrainment, and sleep quality research
GH Secretion Research
Arginine-stimulated GH secretion — overnight pulsatile growth hormone release studies
Sleep-Period Recovery
Glutamine + arginine during overnight period — tissue repair, protein synthesis, gut integrity

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.
