What is Melatonin??

Melatonin (N-Acetyl-5-methoxytryptamine, CAS 73-31-4) is an endogenous indole neurohormone synthesised from tryptophan → serotonin → N-acetylserotonin → melatonin in the pineal gland, with peak release in darkness. Molecular formula C₁₃H₁₆N₂O₂, MW 232.28 g/mol. Melatonin acts on MT1 and MT2 G-protein-coupled receptors (Gi-linked, cAMP suppression) to entrain circadian rhythms. It is also a direct free radical scavenger (hydroxyl, peroxynitrite, superoxide), upregulates glutathione peroxidase and superoxide dismutase, and participates in immune modulation and mitochondrial protection at the cellular level.

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.
