Research background
Oxytocin is the famous “love hormone,” a tiny nine-amino-acid peptide the body makes naturally and one of the most studied molecules in behaviour research. This is lab-made oxytocin as a freeze-dried powder in a 10 mg vial. Prefer it ready-made? See our oxytocin nasal spray.

Summarizes published preclinical literature. Provided for research reference only; not a claim of efficacy or a description of human use.
Reconstitution
- Supplied as a lyophilized (freeze-dried) powder for laboratory reconstitution.
- Bacteriostatic water (0.9% benzyl alcohol) is the most common reconstitution solvent for multi-use research handling; sterile or acetic-acid solutions are used for specific compounds.
- Introduce solvent slowly against the vial wall rather than directly onto the powder, and allow it to dissolve without vigorous shaking.
- Use the reconstitution calculator to determine solvent volume for a target concentration in your protocol.
Storage & handling
- Lyophilized powder: store sealed at -20 °C for long-term stability; short periods at 2–8 °C are generally acceptable.
- Once reconstituted: refrigerate at 2–8 °C and protect from light; use within the compound-specific window noted on the COA.
- Avoid repeated freeze–thaw cycles of reconstituted solution.
- Keep away from direct light and heat at all times.
Purity & verification
Third-party tested for HPLC purity and content (≥99% purity), with the Certificate of Analysis for your batch available on request.
