So last night I loaded up a syringe using an 18G pin then swapped it out to a BD 25G pin and sunk the pin in my quad. I then aspirated or thought I did atleast.... This is where it gets interesting, I start pushing on the plunger and nothing is happening so I of course keep trying and even change the way I`m holding the pin and try again. I eventually figured out that the pin was no good, the pin simply did not have a hole through it at all. Strange just thought I`d share my experience.
