Oxytocin is currently in stock at 30 shops, all of which have third-party lab tests on file. Prices range from $19.00 to $89.00 per vial, with a median of $5.80 per mg. Vial sizes range from 2mg to 10mg. Last updated 11 September 2026.
62 shops are known to sell Oxytocin — 35 with a live listing, 27 evidenced by a lab test in the last year. 40 listings are identified, of which 33 can be compared per milligram.
Bigger vials cost less per milligram. The vial, freeze-drying, labelling, lab test and shipping cost roughly the same whether it holds 5mg or 100mg, so per-milligram price falls as fill size rises. Compare within your size band rather than across the whole list.
