Is the oxytocin available in One Peptides intended for use in humans?

NO. Oxytocin available in One Peptides is intended for research purposes only (Research Use Only) and is not a medicinal product. It is not intended for use in humans or animals outside the context of approved research protocols.

What is the purity of the oxytocin offered by One Peptides?

Oxytocin in the One Peptides offer is analyzed by HPLC and mass spectrometry (MS). The exact purity parameters for each batch are documented in the Certificate of Analysis (CoA), which is available for download on the product card.

How to store oxytocin in lyophilized form?

Oxytocin lyophilisate should be stored at -20 degrees Celsius, in a dry place, away from light. After reconstitution, the working solution should be stored at 2-8 degrees Celsius and used according to the requirements of the research protocol.

Are oxytocin and vasopressin the same peptide?

NO. Oxytocin and vasopressin (ADH) are two distinct neurohypophyseal nanopeptides that differ in two amino acid residues. They have different target receptors (OXTR vs V1a/V1b/V2) and distinct biological activity profiles observed in experimental models, although they show some degree of cross-reactivity.

What are the most popular research models using oxytocin?

In the scientific literature, oxytocin is most often used in studies on animal models of social behavior (prairie voles, rodents), in vitro experiments on uterine smooth muscle cell cultures, and in studies of OXTR receptor binding using radioligand and fluorescence techniques.

Oxytocin — a research reagent (OXTR receptor agonist)

Oxytocin is a chemical reagent intended solely for laboratory research (Research Use Only) — a nonapeptide and an agonist of the oxytocin receptor (OXTR), studied in the context of social neurobiology and stress regulation. It is not a dietary supplement, a medicine or a product intended for use in humans.

Research Use Only. The products in this category are chemical substances for laboratory and scientific applications. They are not dietary supplements, medicines or foodstuffs. They are not intended for consumption or for administration to humans or animals, and they do not serve to treat social disorders, anxiety, depression or “bonding”. The descriptions refer to receptor pharmacology and to results reported in the literature — they do not constitute advice or instructions for use.

What oxytocin is in a research context

Oxytocin is a nonapeptide (nine amino acids, a cyclic molecule with a disulfide bridge), naturally produced by the hypothalamus and released by the posterior pituitary. In pharmacology it is an agonist of the oxytocin receptor (OXTR) — a target studied in the context of social behaviour, bonding, social cognition and the regulation of the stress response.

In the research-reagent trade, oxytocin functions as a pure, analytically defined peptide substance — a tool for research into OXTR signalling and social neurobiology, not a form intended for administration to humans. The colloquial name “love hormone” can be misleading: it is a media simplification, not a description of the reagent, whose role in the catalogue is solely for research.

Research oxytocin vs oxytocin as a medicine

As an active substance, oxytocin is also an authorised injectable medicine (Syntocinon, Oxytocin) used in obstetrics — for the induction and augmentation of labour and for lactation, under medical supervision. This is a separate regulatory frame. The research reagent from this category is not a medicinal product, has no obstetric use and does not replace any medicine. The identity of the active substance does not remove the distinction between a medicine and an RUO reagent.

What is studied in the context of oxytocin

The directions below describe what is the subject of research — not effects promised to the user.

OXTR receptor pharmacology — profiling the agonist, intracellular signalling, receptor-activity assays.
Social neurobiology — models of the role of oxytocin in social behaviour and social cognition.
Stress regulation — research into the modulation of the neuroendocrine response.

Regulatory frame

Oxytocin in this category is a chemical reagent with Research Use Only status. It is not a dietary supplement, a medicine or a foodstuff; it is not intended for use in humans or for any use outside a controlled research environment. It should be distinguished from oxytocin as an authorised injectable medicine used in obstetrics — these are separate regulatory frames.
