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

Injectable vs Oral Sleep Compounds

Bioavailability comparison of injectable GABA and melatonin vs oral supplementation
