Oxytocin pricing across our tracked vendors ranges $20.00 (cheapest) to $85.00 (most expensive) — a 325% spread for what should be the same compound. Median is ~$31.95. That's a huge spread, which usually means the cheapest vendor is either passing on bulk-buying advantage or cutting corners on QC. Always cross-check the cheapest vendor's COA before ordering.

Why this page exists

Peptide prices vary wildly between vendors — sometimes by 3x or more for the exact same compound at the same purity. Vendors use different quantity sizes to obscure comparisons. PeptidePrices normalizes every price to a standard unit so you can see the real cheapest deal.

How we rank: Only in-stock listings are shown. Prices are deduplicated per vendor (cheapest variant only). Non-normalized listings (missing quantity data) are excluded. See our full methodology.
