How many vials are in a Oxytocin Acetate kit?

Every kit is 10 vials. The "5mg" label means 5 mg per vial, so a 5 mg kit gives 50 mg total, a 10 mg kit gives 100 mg total, and so on.

Is the price per vial or per kit?

Prices shown are for the full 10-vial kit. We always show the per-vial and per-mg breakdown so you can compare honestly.

What payment methods do you accept?

SEPA bank transfer (IBAN) is our default — secure, fee-free, instant confirmation. We can also send a secure card-payment link on request via WhatsApp.

Do you ship outside the EU?

Yes — UK, USA, Middle East, Asia and Australia. EU is fastest (5–14 days). International is tracked and discreet. Some destinations are restricted — checkout will tell you.

How is purity verified?

Every batch is independently tested by HPLC and mass spectrometry. We can send the batch-specific COA for your order on request.

Is this intended for human use?

No. Oxytocin Acetate sold by Regena Peptides is a research compound supplied strictly for in-vitro laboratory investigation by qualified professionals. Not for human or veterinary use.

Sold as 10-vial kits · minimum order

We don't sell single vials. Every order is a sealed 10-vial research kit — it's how serious labs and long-protocol researchers actually buy, and it's how we keep quality and price honest.

✓ Lower €/mg — batching 10 vials cuts our fill cost, and we pass it to you (per-vial price is 40–60% lower than typical single-vial pricing).
✓ One batch, one COA — all 10 vials come from the same HPLC-verified lot, so your data stays consistent across a full study.
✓ Lasts 8–12 months — a sealed 10-vial kit keeps for roughly 8–12 months in cold storage, so you're not re-ordering mid-study. Once mixed with bacteriostatic water, a vial lasts about 2 months in the fridge (2–8 °C).
✓ One shipment, one customs pass — fewer parcels = lower risk, lower shipping cost per vial, faster to your bench.

1 kit = 10 vials. Bigger vials = lower price per vial.

What is Oxytocin Acetate?

Oxytocin acetate is the salt form of the endogenous nonapeptide oxytocin. It is widely used as a research probe for OXTR signalling in neurobehavioural, lactation and smooth-muscle laboratory models.

Mechanism of action

Selective oxytocin-receptor (OXTR) agonism with weak V1a vasopressin activity.

Primary research areas

Social-behaviour, pair-bonding and uterine-smooth-muscle research models.

Research notes

Plasma half-life is short — intranasal and acute IP exposures dominate CNS research designs.
Cross-reacts weakly with V1a; selectivity controls (e.g. atosiban) are standard in receptor pharmacology work.

Third-party COA — testing in progress

Pending

The current Oxytocin Acetate batch is with our independent laboratory (Janoshik Analytical / VidaLabs) for HPLC + Mass Spectrometry analysis. Published COAs for previously-tested compounds are available in our full COA library.

Need the batch-specific COA for your order? Email support@regena-peptides.com — we'll send it as soon as the lab returns the report (typically 5–10 business days after shipment).

Verified
COA matched batch number exactly
Ordered three batches of BPC-157 over four months. Each shipment arrived cold-packed with a COA and the batch numbers cross-checked against the public testing database. Purity reported between 98.7% and 99.2% — consistent with what we measured in-house by HPLC.
Dr. M. AnderssonStockholm, Sweden
Verified
Fast UK delivery, clean reconstitution
Discreet packaging, arrived in 5–14 days to London. Lyophilised cake was firm, dissolved completely in bac water with no cloudiness. Dose math in IU on the calculator made repeat dosing trivial.
J. WhitmoreLondon, UK
Verified
Best documentation I've seen from a supplier
We compared three suppliers as part of a sourcing audit. Regena was the only one with chromatograms, retention times and lab-named COAs published per batch. That's the standard the rest of the industry should meet.
Prof. L. RomanoMilan, Italy
Verified
Good product, customs took an extra day
Product itself is excellent — clean reconstitution, COA available. Customs added 24 hours which is outside Regena's control. Support replied within an hour when I asked for an update.
K. PetersenCopenhagen, Denmark
Verified
Independent lab agreed with stated purity
We sent a sub-sample to an independent lab. Their result was within 0.4% of the published Regena COA. That's a level of transparency you almost never see in research-peptide sourcing.
Dr. S. PatelBirmingham, UK
Verified
Cold chain held the whole way
Temperature indicator strip in the package stayed in the green. Vials still chilled on arrival despite a 3-day route. Whoever packs these boxes knows what they're doing.
A. MüllerBerlin, Germany
