No I do not shave my legs. And I know it is not the needle. Because I used the same needle to later inject the Deca. You are wondering what I do and why I use the same needle? Ok, let me explain. I shoot 2 substances per session. I use 2 pins (p1 and p2) and two syringes (s1 and s2). I first fill S1 with Test using p1. I then remove p1 from s1 and place p2 and s1. I now put p1 on s2 and draw the Deca. I inject the test (s1 and p2) and then transfer p2 to s2 and inject the Deca. (I hope I did not loose you with the pa p2 s1 s2 thing

)I use 91% alcohol to clean everything including my skin at point of injection. I also use alcohol afterwards after injection to clean any blood or anything else.
This method has always worked in the past with no problem like the one I have now. I think it might be bad test but the hair thing sounds very viable. But I did clean the area with alcohol before and after the shot.
BTW As previously stated will a Bandage and ointment over the injection site work?
