buying pins from the pharmacy

[legobricks]

21G 1 1/2" is what any doctor, hospital would use for IM (oil based) when injecting in the glutes or even lower back. 23G 1" is what I use for shoulders, biceps and quads as there is little fat in these areas (also what I received when in hospital)
Where do I get my info from? I work in a Pharma Co so there are many people here with that kind of knowledge.25G aren't long enough and also from what I see is the prefered choice of the local druggy's around here........now that would arouse suspicion buying those in the pharmacy

Wow, look at the bolded comments....

as stated 25g is not the length of the needle as you can get it multiple lengths. Also, 25g is perfect for shooting as you shoot slow letting the oil disperse in the muscle. 23g is fine too but less scar tissue the better IMO.

And as well, normally slin pins are used for drugs....well i guess whatever they can get there hands on.
