The yellow Xanax bars at 2mg. Dont pay more for them. SWIM pays/sells $2 a mg. No more. I have actually had Pakistani Onax 2mg bars and they were more potent. And actually,sorry to burst your bubble 'Zanax master' but there are 3mg pills, and they are in the US at this point They are actually more common to get because Docs dont worry about abuse as much, not to say SWIY can't parachute them and feel the same (same active ingredient, no gooey filler like OP-contin). And yes they are only XR, but they are the same substance if you chew them up, and have about the same half life. SWIM enjoys them pretty much, thou IR Yellow 2mg/ 1mg Blue Wagonwheels are my favorites, the only true diff. is the doses (1mg,2mg and 3mg for XR), but other than that it's just a mental thing. (For alot of people, if they are sold a 2mg pill, and told its 3mg, they're gonna feel like it's stronger.) Just like I like my IR Roxycodone better than Crushed Oxycottin.
The 3mg XR's are (at this point) available in the US. The XR are actually easier to get than if you ask your doc for the IR ones. Personally, if you chew them up, I find no diff. in strength or duration.
The Yellow 2mg Bars: (These are same as the whites, anyone who tells you differently... aren't wrong, but the whites and yellows are the same dose so dont pay extra. Iit is purely from a subjective p.o.v.
PLEASE KEEP THAT IN MIND
The ONAX 2 Pakistani Xanax Bars: (Extremely rare, personal favorite)
Took 2 and was sleeping within an hour or so. For some reason, seems to have only potency diff. of all the xannies SWIMs done.) But then again, theres usually no or only a minor active chemical alterance.
And these are The Xanax XR 3mg (Comes in 1,2,3mg)
Another favorite SWIM's Personally been RX'd.
When parachuted, give effects almost identical to IR Xanax. Give extra 10 minutes for effects and a whole glass of water, just in case.
To end, taking the same amount of that active substance (alprazolam) will lead to same effects (only you HAVE TO CHEW XANAX XR FOR THE 'RUSH', though some swear brand names and certain off brands work better for them. Know your body, know yur substance, don't get ripped. Have fun, Xanax keeps my functional and not constantly panicking about my severe chronic pain (: Hope I could help
