Buy Relaxation PM — Research Grade Peptide

Relaxation PM is a metabolic & longevity research compound currently in stock directly from a verified Chinese manufacturer. Every batch is tested by the manufacturer for purity and concentration as part of routine quality control. Sourcing is direct — no intermediaries. Minimum order value is $600 USD. International shipping available.

Compound Profile

Relaxation PM is a compounded injectable formulation containing GABA 100 mg, Melatonin 1 mg, L-Arginine 100 mg, and L-Glutamine 25 mg per ml. The formulation targets GABAergic pathway modulation, circadian rhythm signaling, and neurotransmitter-associated metabolic mechanisms in preclinical research contexts.

Each component has a defined neurological or metabolic research role: GABA (γ-aminobutyric acid) is the primary inhibitory neurotransmitter in the mammalian central nervous system, acting on GABA-A (ionotropic, Cl⁻ channel) and GABA-B (metabotropic, K⁺/Ca²⁺) receptors; Melatonin is the pineal hormone that regulates circadian rhythm via MT1 and MT2 melatonin receptors, with additional antioxidant activity as a hydroxyl radical scavenger; L-Arginine is the substrate for neuronal nitric oxide synthase (nNOS) and is studied in neurological contexts for NO-mediated synaptic signaling; L-Glutamine is the primary brain ammonia buffer and an inter-organ nitrogen carrier, serving as a precursor for both glutamate and GABA synthesis.

PeptidesFromChina.co supplies Relaxation PM as a sterile liquid formulation with component concentrations verified by the manufacturer per batch. For laboratory research use only.

Specification Highlights

Quality & Testing

Testing method: HPLC / LC-MS. Every batch is tested before shipment. Purity ≥99% confirmed per batch.

Every batch is tested by the manufacturer for purity and concentration as part of routine quality control, using methods such as HPLC and LC-MS. These results are kept in the manufacturer's internal quality-control records and are not issued as a separate certificate or document.

Research Areas

GABAergic Pathway Research

GABA-A and GABA-B receptor pharmacology is studied in neuronal cell cultures (primary cortical neurons, GABAergic interneuron preparations) and brain slice preparations. GABA-A receptor modulation (chloride conductance, inhibitory postsynaptic potential frequency and amplitude) and GABA-B receptor signaling (Gi/o-coupled K⁺ channel activation, Ca²⁺ channel inhibition) are measured electrophysiologically. The Glutamine-Glutamate-GABA cycle — where Glutamine is converted by glutaminase to Glutamate and then by GAD (glutamic acid decarboxylase) to GABA — is an additional research axis provided by the L-Glutamine component.

Circadian Rhythm and Melatonin Signaling

Melatonin acts on MT1 receptors to suppress SCN (suprachiasmatic nucleus) firing and on MT2 receptors to phase-shift the circadian clock. Research using melatonin examines receptor binding kinetics (radioligand displacement with 2-[¹²⁵I]-iodomelatonin), circadian phase resetting (Per1/Per2 gene expression in circadian reporter cell lines), and antioxidant activity (ORAC, DPPH assays). Combined with GABA (which also modulates SCN activity via GABA-A receptors), the formulation provides dual inhibitory tone for sleep-related neurophysiology research.

Frequently Asked Questions

What are the research applications for Relaxation PM?

Primary research areas include: GABAergic neuropharmacology (GABA-A/B receptor studies in neuronal models), circadian rhythm biology (melatonin MT1/MT2 receptor pharmacology, circadian phase shifting), neuronal NO signaling (nNOS substrate with L-Arginine), and glutamine-GABA metabolic cycling. The combination is also used in sleep-wake cycle research examining the combined inhibitory effects of GABA and Melatonin on SCN activity.

Does systemic GABA cross the blood-brain barrier?

Endogenous GABA has limited CNS penetration via systemic administration under normal physiological conditions due to low BBB permeability. In vitro and ex vivo neurological research — using primary neuronal cultures, brain slice preparations, or direct CNS administration models — circumvents this limitation. For systemic research designs examining peripheral GABA receptor systems (enteric nervous system, immune cells), the compound is studied in those peripheral contexts directly.

What are the storage requirements?

Relaxation PM should be stored at 2-8°C, protected from light. Do not freeze. Use within the date specified on the label.
