What is — Melatonina
Melatonin (N-acetyl-5-methoxytryptamine) is an indoleamine signaling molecule supplied by Peptworks as a lyophilized 10 mg vial for laboratory research use only (RUO). It is offered as a B2B wholesale and white-label reference reagent from EU stock, with >=98% HPLC purity and an independent per-batch Certificate of Analysis (HPLC + heavy metals). It is not a medicine, supplement, cosmetic or medical device, and is not intended for human or animal consumption.
In research models, melatonin is characterized as a ligand for the high-affinity G-protein-coupled receptors MT1 and MT2, and is studied for direct interactions with intracellular targets. Its lipophilic and amphiphilic properties are examined in the context of membrane permeability and its role as a signaling molecule in chronobiology assays. Melatonin is also investigated in vitro for direct free-radical-scavenging and indirect antioxidant activity. All mechanistic descriptions refer strictly to preclinical, in-vitro and animal research systems.
Research
- Chronobiology and circadian-rhythm signaling models
- In-vitro antioxidant and free-radical-scavenging assays
- MT1/MT2 receptor pharmacology and binding studies
- Mitochondrial function and oxidative-stress research models
- Neuroscience and sleep-wake cycle animal models
- Immunomodulation research in cell-culture systems
Advantages
- Studied as a chronobiotic reference compound in circadian-rhythm research models
- Used in vitro as a comparator in antioxidant and oxidative-stress assay development
- Serves as a reference ligand in MT1/MT2 receptor pharmacology experiments
- Applied in preclinical neuroscience models investigating sleep-wake signaling
- High-purity (>=98% HPLC) lot-controlled reagent supports reproducible research data
Safety
- Transient sedation-like behavior reported in rodent research models
- Reduced body temperature (hypothermia) observed in some animal studies
- Dose-dependent changes in locomotor activity reported in preclinical models
- Generally low acute toxicity profile described in the animal research literature
- These observations pertain to laboratory research systems only, not to humans
Ideal for
- Chronobiology and circadian-rhythm laboratories
- Antioxidant and oxidative-stress assay development
- Receptor pharmacology and binding-study workflows
- Resellers building a white-label research-reagent catalogue in the EU
- Distributors needing lot-traceable bulk vials with per-batch CoA
This product is a laboratory reagent supplied strictly for research. It is not a medicine, food or supplement and is not for human or veterinary use. It must be handled by qualified professionals under laboratory conditions.
Frequently asked questions
Where can I buy Melatonin in bulk in the EU?
Peptworks supplies Melatonin (10 mg lyophilized vials) as a B2B wholesale and white-label research reagent from stock already inside the EU. Orders ship intra-community in 3-5 business days with no customs. Minimum order is 10 units (one box) per reference, purchased either as unbranded bulk vials or white-labelled under your own brand.
What is the wholesale price per vial for Melatonin?
Public per-vial pricing starts at EUR 19.00/vial at the 100-unit tier. Combined-order volume discounts apply to the whole order by total units: 300u = EUR 15.58/vial (-18%), 500u = EUR 14.25/vial (-25%), 1000u = EUR 12.92/vial (-32%). It is a single tier by combined total units, not stacked. Payment is by USDC bank transfer / invoice.
Can I get Melatonin white-labelled under my own brand?
Yes. Peptworks offers two formats: unbranded bulk vials, or white-label with your own brand printed on the label and boxed. A one-time label setup fee of EUR 180 applies to orders under 100 units and is free from 100 units. Vials ship in boxes of 10; the box carries the Peptworks label plus a unique QR linking to that batch's CoA.
What is the minimum order for Melatonin?
The minimum order is 10 units, which equals one box, per reference. Vials always ship in boxes of 10. You can combine references across your order, and the volume discount tier is calculated on the combined total units of the whole order.
How is the Certificate of Analysis (CoA) verified?
Every batch ships with an independent per-batch CoA covering HPLC purity (>=98%) and heavy metals. The box carries a unique QR code that links directly to that batch's CoA and is verifiable through Peptworks, so your customers can confirm authenticity per batch.
Is Peptworks Melatonin for human use?
No. All Peptworks products, including Melatonin, are Research Use Only (RUO) laboratory reagents. They are not for human or animal consumption and are not a medicine, supplement, cosmetic or medical device. Peptworks sells B2B to resellers and laboratories only, not to end consumers.
