Trying to prep these instant release oxys for IVing, tossed 1.5 crushed Roxy 15s (looking to try to IV about 20-25 mg oxy), but when I mixed the powder with cool water it looked like it was starting to foam up.

I know that these oxys are the best ones to shoot b/c they have no time release cellulose, but it just looks to me like I might not be getting all the oxy out of the powder. After I tried the 22.5 mg shot of oxy, it felt pretty weak and I was thinking that snorting would give all the oxy to me.

Anyone here knowledgeable enough to know if the instant release oxys have an anti-abuse mechanism? I sort-of don't think there is any, it just sux to not get all of the oxy I paid my hard-earned cash for.

Anyone out there whos tried both IVing and snorting these kinds of pills, and has a distinct preference (to IV or to snort), I could really use your input here.

Edit: One thing I might be running into trouble with this is being that I'm out of 1 CC rigs, I've been using about 1/2 mL of water to dissolve the powder so I'd be able to fit the shot into my 1/2 CC rigs, the only ones I've got access to for the last week or so. Is this just nowhere near enough water for me to be able to dissolve the pills with?
