What is — Oxitocina
Oxytocin (Oxytocin acetate) is a nine-amino-acid cyclic peptide supplied by Peptworks as a lyophilised 5 mg vial for laboratory research use only. It is a research-grade reference reagent, not a medicine, supplement, cosmetic or medical device, and it is not for human or animal consumption. Each batch is characterised at >=98% HPLC purity with an independent Certificate of Analysis (HPLC plus heavy metals). Peptworks supplies it B2B only, as bulk unbranded vials (white-label), with stock held inside the EU.
In experimental systems Oxytocin acts as an agonist at the oxytocin receptor (OXTR), a class A G-protein-coupled receptor. Receptor engagement in vitro is associated with Gq/11 coupling, phospholipase C activation, inositol trisphosphate generation and mobilisation of intracellular calcium; cross-reactivity with vasopressin receptors is also studied in binding assays. These signalling steps are described strictly within cell-based and animal research models and characterise the peptide's use as a laboratory tool compound, with no human application implied.
Research
- Oxytocin receptor (OXTR) pharmacology and radioligand/competition binding assays
- GPCR signal-transduction studies (Gq/11, phospholipase C, intracellular calcium readouts)
- Smooth-muscle contractility in isolated tissue preparations (e.g. uterine and myoepithelial models)
- Behavioural neuroscience in animal models (social behaviour and pair-bonding paradigms)
- Neuroendocrine and stress-axis signalling research in preclinical models
- Analytical method development and reference-standard characterisation (HPLC, MS)
Advantages
- Well-characterised OXTR agonist suitable as a tool compound and positive control in in-vitro assays
- >=98% HPLC purity with an independent per-batch CoA (HPLC + heavy metals) for reproducible research
- Lyophilised 5 mg format for flexible reconstitution across assay formats
- Batch traceability via a unique QR on the box linking to the CoA, verifiable through Peptworks
- EU-held stock enabling fast intra-community resupply for ongoing research programmes
- Available bulk or white-label so resellers can serve their own research-market clients
Safety
- As a Research Use Only reagent it has no approved human or veterinary use; the following reflect observations reported in preclinical/in-vitro literature, not human effects.
- Uterotonic (contractile) activity reported in isolated smooth-muscle and tissue-bath preparations
- Receptor desensitisation and internalisation observed with sustained agonist exposure in cell models
- Transient cardiovascular changes (e.g. heart-rate and blood-pressure shifts) reported in animal studies
- Cross-reactivity at vasopressin receptors reported in binding assays, relevant to selectivity controls
- Peptide is sensitive to degradation; handling, reconstitution and storage conditions affect assay results
Ideal for
- Academic and commercial laboratories running OXTR pharmacology and GPCR signalling assays
- Groups performing smooth-muscle contractility and isolated-tissue studies
- Behavioural neuroscience programmes using validated animal models
- Analytical labs needing a characterised peptide reference standard
- B2B resellers and distributors building a white-label research-peptide catalogue in the EU
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 Oxytocin in bulk in the EU?
Peptworks is a B2B wholesale and white-label supplier with Oxytocin (Oxytocin acetate, 5 mg lyophilised vial) held in stock inside the EU. Orders ship intra-community in 3-5 business days with no customs. It is a Research Use Only reagent; Peptworks does not sell to end users. Orders start from a 4-vial pack per reference.
What is the wholesale Oxytocin price per vial?
Oxitocina 5mg has two public per-vial prices: €31.90 in a 4-vial pack and €20.00 from 10 vials of this reference (box price). There are no volume tiers. Shipping is free on orders from €500 (€24.90 below), inside the EU with no customs.
Do you offer Oxitocina as white-label?
Yes, in the white-label sense: Oxitocina comes in unbranded vials, with no brand on the vial, so you can resell it under your own label. Peptworks does not print or apply labels. Every batch is tested by an independent lab and ships from EU stock with no customs.
What is the minimum order for Oxytocin?
The minimum is a 4-vial pack per reference; from 10 vials of a reference the lower box price applies. Vials ship in boxes of 10. There are no volume tiers, and orders from €500 ship free.
How is the Oxytocin CoA verified?
Every batch has an independent Certificate of Analysis (HPLC purity plus heavy metals), with purity specified at >=98% HPLC. Each box carries a unique QR that opens that batch's CoA, verifiable through Peptworks so your own clients can confirm authenticity.
How do I pay and how fast does it ship?
Payment is in crypto: USDC or USDT (Polygon or Base) or Bitcoin — paying in crypto is what keeps our prices this tight, with no card or bank fees. there is no card checkout on the site. Because stock is already inside the EU, orders ship intra-community in 3-5 business days with no customs. The site is available in 10 languages (ES, EN, DE, FR, PT, IT, NL, PL, CS, EL).
