Is it overly thick?
I've never had a problem with amps except the first time, broke two before getting a scoring tool.
Now I always use the scoring tool to take off the top and draw it right up, usually a 23 or 25 ga.
I assume they are 1ml amps/single dose?
Did you get any? Or none at all?
Never heard of someone not being able to draw any oil from the amp.
I need more details.
