What you want to see is an air bubble which means the spot you chose is not where a vein runs but just plain solid muscle or empty space free from veins. If u see a small bubble run up then u can start to inject the gear. However if u happen to draw blood when u pull the plunger back then you have to withdraw the needle change it and inject a different spot, as you were hitting a vein the last time. Remember to aspirate again though.
Some may ask about the air bubble running up the syringe, saying that isn't it necessary to get rid of all air bubble before injecting? Thats true you have to clear off the air bubbles before you inject ureself. In the case of aspiration the air bubble is caused because the spot u injected is more like a vacum filled spot. Hence it is safe to inject the gear down once u see the air bubble come up the syringe. Good Luck.
