Full shipping informationResearch-grade Oxytocin Acetate. Class-level specification ≥98% (10mg: ≥97%). Lyophilized powder in sealed glass vial. For research purposes only. Not for human consumption.
Description
Oxytocin is a nine-amino acid neuropeptide produced in the hypothalamus and released from the posterior pituitary. Its roles span social bonding, uterine contractions, lactation, and neuromodulation — a breadth that has made it one of the most studied peptides in behavioral and social neuroscience over the past 30 years. Oxytocin acetate is supplied here for research applications requiring the endogenous sequence.
The “love hormone” or “bonding hormone” framing is popular but oversimplified. Oxytocin’s effects in research models are context-dependent and sometimes counterintuitive — studies report both enhanced prosocial behavior toward in-group members and hostility toward out-group members. The oxytocin receptor (OXTR) is expressed in the hypothalamus, limbic system, and throughout the periphery including uterus, mammary gland, and cardiovascular tissue. This broad expression pattern means oxytocin has multiple research contexts beyond behavioral neuroscience: it is studied in research models for anti-inflammatory properties, HPA axis stress-response modulation, cardiovascular function, and roles in metabolic homeostasis.
In reproductive biology, oxytocin’s pharmacology is well-characterised: it is studied for stimulating uterine smooth-muscle contraction and milk ejection through OXTR signalling, mechanisms that have been extensively documented in research models and provide a large body of pharmacological data on the peptide.

Is oxytocin really a “love hormone”?
The “love hormone” framing captures a real research finding but oversimplifies the pharmacology significantly. In research models, oxytocin is associated with enhanced social bonding, trust, and affiliative behavior in many studies — particularly within recognized groups. But studies also report increased in-group favoritism and out-group hostility in some experimental contexts, heightened envy and gloating, and effects that vary substantially by individual, context, and baseline social environment. The research picture is that oxytocin amplifies social salience broadly rather than simply promoting positive bonding — which explains why it is associated with pro-social and anti-social effects depending on context.
What are oxytocin’s effects beyond social behavior?
Oxytocin has well-documented effects in research models outside social neuroscience. In reproductive biology, it is studied for stimulating uterine contractions and milk ejection — the basis for a large body of research on its smooth-muscle pharmacology. It is studied for modulating HPA axis function and attenuating the stress response in research models. Anti-inflammatory properties have been reported, with research showing effects on cytokine profiles and immune function. Cardiovascular research includes modulation of heart rate and blood pressure in model systems. More recently, oxytocin has been studied in metabolic contexts — OXTR is expressed in adipose tissue and oxytocin is studied for effects on energy homeostasis and body weight in rodent models.

Why researchers choose CertaPeptides
Who actually tests this?
Selected lots are independently verified by Janoshik Analytical (Czech Republic) and published on the Janoshik public portal. Other lots ship with the supplier's batch specification. See /coa for the published wall.
View COAs →What if I get the wrong batch?
Every vial label carries a code. Look it up on our Verify page: it shows what CertaPeptides publishes for that code and, for a withdrawn lot, that the lot was withdrawn and why. If yours is withdrawn, or if the code on your label finds nothing, email us that code.
View COAs →Where does it ship from?
Romania (EU). We are CERTALAB SRL, CUI 54169956, VAT-registered. Sameday for Romania, GLS for most EU destinations, TCE Worldwide for the remaining cross-border EU and non-EU markets (UK, Switzerland). Delivery 1–15 business days depending on destination — exact window shown at checkout.
Shipping details →What if there's a problem?

Returns policy →Product Information
This product is intended for scientific research and development purposes only. It is a chemical substance that shall not be used as a drug, medicine, active substance, or ingredient in any product intended for human or animal consumption. Researchers must handle this compound in accordance with their institutional biosafety guidelines. Use only in properly equipped laboratory settings with appropriate personal protective equipment.
Peptides in lyophilized (freeze-dried) form are shipped in sealed glass vials using standard delivery methods and do not require refrigeration during transit. Lyophilized peptides are highly stable at ambient temperatures for the duration of standard shipping (typical transit windows are shown at checkout). Once received, transfer the product to refrigerated storage (2–8°C) promptly.
Frequently Asked
Research peptides are supplied in lyophilized (freeze-dried) form. The amount of material is typically only a few milligrams — appearing as a very thin film or small pellet at the bottom of the vial, often nearly invisible. This is completely normal.
Unlike some suppliers who add bulk fillers (such as Mannitol), CertaPeptides provides pure peptide without unnecessary additives.
