I’m very familiar with oxymorphone and I’ve never seen these, and I’ve tried every single strength and brand for the past 7 years. All the 30mg I’ve ever see are ER only. The prior poster is right, I’ve only see IR in 5mg and 10mg. If you’ve received those from the Mexican vendor “D”... BE CAREFUL. A lot of his meds have recently came back as fakes pressed with fentanyl. You should order a test kit. I’ve been ordering from these vendors a LONG time and never ever received those. They don’t look right. They may be Opana, but just be careful!
