Oxytocin in brief
Oxytocin comes in 3 strengths from 2mg to 10mg per vial, each a sealed box of ten, from $26.20 to $76.87 a box. Per mg the spread is wide: OT10 (10mg x 10 vials) works out at $0.769 per mg against $1.310 per mg for OT2 (2mg x 10 vials), 41 percent less for the same mg, because the vial, the fill and the testing cost about the same whatever the vial holds.
Nothing is held on the shelf: every strength is special order, brought in on a 50-box minimum rather than held in stock; ask the desk for the date before ordering.
What Oxytocin is
Oxytocin is a cyclic nonapeptide amide, CYIQNCPLG-NH2, average mass 1007.2, with a disulfide bridge between cysteines 1 and 6 closing a six-residue ring and a three-residue tail ending in glycinamide. Supplied as the acetate.
It has two deamidation sites side by side, glutamine 4 and asparagine 5, and the disulfide can open under reducing conditions or scramble at high pH, so the deamidated forms and the dimer are the impurities to expect. No methionine or tryptophan. Moderately hydrophilic; store cold.
Oxytocin beside Kisspeptin-10 and Gonadorelin
Oxytocin works out at $0.769 per mg at 10mg (OT10, in 50-box lots), its lowest. Its neighbours, on price alone: Kisspeptin-10 at $0.907 per mg at 10mg (KS10), 1,302.5 g/mol; Gonadorelin at $0.893 per mg at 5mg (GND5, in 50-box lots), 1,182.3 g/mol.
Reading an Oxytocin certificate of analysis (COA)
Identity by mass. Average mass 1007.2 (C43H66N12O12S2). In electrospray the protonated ions come near m/z 1008.2 (singly charged), m/z 504.6 (doubly charged); on our certificates the measured mass is matched to the calculated average mass, within about one unit; the calculated mass is two units below the fully reduced chain.
- Oxidation: 2 cysteines held in a disulfide bridge, and the reduced form, with the bridge opened, is 2 heavier. Store in the dark and keep the vial sealed.
- Deamidation: 1 asparagine and 1 glutamine. The deamidated form is 0.984 heavier and a little more negatively charged, inside the tolerance of the average-mass line; telling it apart takes a high-resolution mass, which the certificate does not carry.
- Charge: near neutral pH about +1, basic.
Worked out from what the sheet holds for this line; the batch certificate is the record. How to read one, and verify a batch number.

Questions about Oxytocin
Which other peptides on the list close a ring, and how is Oxytocin’s closed?
Oxytocin’s ring is six residues closed by a disulfide joining cysteines 1 and 6, and the last three residues hang outside it, ending in glycinamide. Cagrilintide closes a ring between its cysteines 2 and 7 the same way, cysteine to cysteine, as does adipotide in its CKGGRAKDC segment, and insulin holds three disulfides, two of them joining its chains. MT-2 and PT-141 close theirs by a lactam from an aspartate to a lysine and contain no sulfur at all, so their related substance of note is instead the open-chain precursor, the chain before its ring was closed.
How much does Oxytocin cost?
It is sold only by special order, 50 boxes per strength, from $26.20 a sealed box of 10 vials, up to $76.87 for the largest strength, which works out at $0.769 per mg at its best-priced size. The smallest order is 50 boxes of OT2, $1,310.00 of goods, with freight included to a US address. Every strength and its price per vial is in this page’s price table.
Which Oxytocin size is cheapest per mg?
OT10, 10mg x 10 vials, at $0.769 per mg, which is 41 percent less per mg than OT2, at $1.310 per mg. Larger vials cost less per mg across this range, so match the vial to the size of the work first, then compare per mg.
Can I buy a single vial of Oxytocin?
No, and not a single box either. Oxytocin is a special-order line, brought in on a 50-box minimum rather than held in stock, so the smallest order is 50 sealed boxes of one strength: for OT2, 2mg x 10 vials, that is 50 boxes at $26.20, $1,310.00 of goods. A box is sealed at fill with its batch number on it, and splitting one would break the link between the vials and their certificate.
Which Oxytocin strengths are in stock today?
None today. OT2, OT5 and OT10 are special order: brought in on a 50-box minimum rather than held in stock; ask the desk for the date before ordering.
How is Oxytocin stored?
At minus 20 degrees Celsius, dark and dry. Lyophilised powder tolerates a short spell at ambient temperature in transit, which is why boxes ship without ice. Storage and handling.
What is in a box of Oxytocin?
Ten sealed vials of one strength, each labelled with the product code, the strength and the batch number; the trade also calls a box a 10-vial kit. Oxytocin is supplied as a powder in a sealed glass vial and in no other presentation. Its specification sheet carries the catalogue name, Oxytocin Acetate. Boxes are not split.
Is a certificate of analysis (COA) provided for Oxytocin?
Yes. For Oxytocin the batch certificate reports its purity, net content and identity by mass spectrometry. The other lines on this page are the specification it is made to, and the desk answers for them on a particular batch. The certificate is sent with the shipment, and again on request, and any batch number can be verified on the certificate page.
Is this for human use?
No. Everything here is supplied for laboratory research only, to trade accounts, and is not for human or animal consumption. The research-use page sets out who can buy and what is not sold.
