Here in the UK one brand of oral oxycodone solution is called OxyNorm, like OraMorph (Oral Morphine Solution 10mg/5ml) but the OxyNorm liquid is 1mg/1ml.
It's got a lot of citric acid in it, to give it a 'lemon' flavour, it's very sour but easy to chug down.
OxyNorm is also a brand of instant release oxycodone capsules, 5mg, 10mg and I'm not sure about this but there maybe 20mg too.*
Lynlor is another brand of instant release oxycodone but I'm not sure if they're capsules or tablets.
*Do not empty OxyNorm capsules and snort them, it's a lot more than just oxy' in there.
I snorted a load before and stopped about 1/4 of the way through cause it's a shit load of powder, it was going to the back of my throat/possibly my lungs and intranasal oxycodone only has a bioavailability of 25% and that's when pure oxycodone powder is used!
