I have never used this method but it only makes since to me so use 1cc per every 10mg of the Oxymorphone. Make sure your stir it up good(after the pill shell is removed and dosage would go: 1/2cc 5mg 1cc 10mg 2cc 20mg 3cc 30mg 4cc 40mg ....again this is just me thinking out loud and if i were to use this method it's the way i would approach it.
