Ok guys... I kinda have a two part question. While I was injecting my shot in my delt (anywhere for this matter), my friend told me I was injecting to fast. How fast do you guys usually go? Its not like im trying to win a race or anything... but i just start and finish. He says it takes him atleast 1-2 minutes. He also said it helps decrease chance of absys things (spelling) and pain.... ????

Secondly, when i aspirate, sometimes i get bubbles on the top of the syringe instead of right at the needle. What does that mean and is it bad?

Thanks guys!!
