@Sosomafied - Wise words mate.
For what it's worth, I've even known people who somehow managed to IV clonazepam extracted from tablets. ALL benzodiazepines have the potential to produce unusual behaviors but it's been noted that when administered by a parentheral route, the subjective effects can be more like those of a barbiturate. Most people will simply fall asleep but a few will remain awake and with the loss of inhibition, exective function and memory (both retrograde and anteriorgrade), they can display bizarre behaviors.
It seems that even once reliable sources of those potent RC benzodiazepines are now simply putting whateve they have into a bag and sending it to customers. So while buyers will likely get a benzodiazepine of some sort, I suspect if they offer three, the truth might be that in fact they have one - the just misrepresent the ones they don't have.
The UK in particular has seen a lot of fatal ODs in which people mixed 'street Valium' with an opioid. It used to be etizolam but in quite high doses as that was the cheapest option. Now, who knows what is in those fakes.
So absolutely do stick to medicines whose provinence you know.
BTW I knew of someone who was producing, packaging and selling 10mg diazapem tablets in blister-packs. Now to be fair, at least it was diazepam and was the dose stated - but if those packaging machines can be obtained, it suggests that even when sold in it's patient-pack, it isn't certain to be what it's represented as being.
In short - only trust things you yourself get from your local pharmacy. Even then the occassional error does occur. Last year there was a mix up where 30mg and 60mg morphine tablets were mis-labelled. Luckily nobody was harmed but it shows that it can happen.
