About Melatonin
What is Melatonin?
Overview
What is Melatonin?
Melatonin is the hormone the pineal gland makes at night. It is not a peptide: it is a small molecule, N-acetyl-5-methoxytryptamine, made in the body from serotonin. It is one of the most studied compounds in circadian-rhythm research and acts mainly through two receptors, MT1 and MT2. Supplied as a lyophilised powder in sealed vials, boxed in tens, for laboratory research use only.

| Research status | Melatonin has one of the largest research records of any compound in this catalogue, including decades of human trials. That record is for licensed and supplement products; the material sold here is a research reagent. |
| Documentation | Batch-specific third-party COA |
These are catalogue target specifications, not batch results. The 99%+ purity figure is the specification we buy to. The authoritative figures for any particular box are the ones printed on that box’s Certificate of Analysis, which is lot-specific. What research grade actually means explains the difference. Terms such as HPLC purity and net peptide content are explained in the peptide glossary.
We make no “third-party verified” claim for a batch unless the matching report is supplied with it. Ask for the current COA for the lot in stock before you order — we will send it.

Storage & reconstitution
Handling
How should Melatonin be stored and reconstituted?
Sealed vials tolerate ambient temperature in transit and keep at −20 °C beyond that. Reconstitute slowly down the vial wall, swirl rather than shake, then refrigerate at 2–8 °C and aliquot before freezing.
Why each of those matters, and what a freeze–thaw cycle actually costs: peptide handling and storage reference. How long a mixed vial keeps: reconstituted peptide shelf life.
What it is researched for
Research Context
What is Melatonin researched for?
Below is a plain-English summary of what published research has investigated, and what it has found. These are descriptions of research activity and published results. They are not claims about what Melatonin does, and nothing here is a statement that it is safe or effective for any purpose.
Circadian research
Melatonin is released at night under the control of the body's master clock, and signals the time of day to tissues through the MT1 and MT2 receptors. 1

- Comparative work alongside DSIP and other compounds in sleep-architecture models
Batch COA
Verification
Does Melatonin come with a COA?
Yes — every box. Each batch of Melatonin is analysed by an independent third-party laboratory, and the certificate is tied to the batch number on the vial label.

Questions & answers
Questions
Melatonin questions, answered
Is melatonin a peptide?
No. Melatonin is a small molecule of 232 g/mol made from the amino acid tryptophan via serotonin, not a chain of amino acids. It is catalogued with the vitamin and amino blends because it is ordered alongside the research peptides.
Is melatonin a medicine?
In the UK, melatonin is a prescription medicine in some forms, such as prolonged-release tablets, and elsewhere it is sold as a supplement. The material sold here is neither: it is a laboratory reagent, not for human consumption.
How much does Melatonin cost?
Melatonin starts at $8.33 per vial, sold in boxes of 10 vials at $83.28 per box (about £62.39). 1 strength available: 10 mg. There is no minimum order.
Can I buy Melatonin 10mg vials in the UK?
Yes. Melatonin 10mg comes in boxes of 10 vials at $83.28 per box ($8.33 per vial, about £62.39 per box), sent tracked to UK addresses. There is no minimum order.
How is Melatonin shipped to the UK and USA?
Tracked to the UK, USA, EU and worldwide, in plain packaging, dispatched within 1–2 working days. Country-by-country estimates are on the shipping page.
