Hi just did a pin earlier today... its test enanthate 250.

First question is: after i pinned i noticed there was still a small amount of test in the syringe even though the plunger was fully pushed in, is this common with all syringes??as the brand i am using is a very reputable brand.

Second question is: there was a small amount of air in the very top of the syringe, a little bubble. While trying to get rid of it i was pushing on the plunger and wasting some test running down the outside of the syringe. Is there way to stop this? as it has not happened before??

Not particurarily worried, i just down want to be injecting a little air bubble or wasting my test

Thanks in advance
