Blood, but sometimes no blood when injecting?

[VenicePump]

Why is it sometimes when I inject then pull it out no blood comes out. Then other times it does. I do notice sometimes though liquid pusses out a little bit. I think that's the test coming out (minutely).

No advice from me personally but I'm sure someone will be along to help out, hopefully it's nothing major

Have you ever tried gently pulling skin to side, injecting deep, then letting skin go back? Sorta puts the injection in a different area from where the skin was entered. The blood thing just happens, but the oil coming out can be avoided.

Because sometimes you hit a small blood vessel, and sometimes you don't.

Sometimes you run into a random blood vessel when you pin. Remember, you're sticking a needle through your skin to get to the muscle. Plenty of blood vessels there to get nicked. Don't worry about it though, as long as you don't get any blood when you aspirate. As for the test leaking out, inject slowly, and try leaving the needle in for 30 seconds to a minute after you finish.

Don't worry about your gear, very little amount or nothing at all was wasted.
