What it costs
| Vial | Listed price | Per mg | vs peer median | Listing |

Read from the vendor’s own store and normalised per milligram, because a smaller vial at a lower sticker price is usually the dearer peptide.
What the laboratory found
No third-party certificate for Oxytocin from Modern Aminos has been located.
That is a statement about the public record, not an accusation. The vendor may test and not publish, or publish somewhere we have not read. What it means for a buyer is that the price above is the only thing established here, and price says nothing about what is in the vial.
Vendors whose certificates you can check yourself lists the ones where that gap is closed.
