Quick IGF slin pin question

I have a bottle of just IGF and BA straight out of the box . Now the question is, if i pull back 4 ticks on the slin pin, that means that I will be drawing 40mcg's, right ? Well, I just saw where someone said that they drew back (10iu's = 50mcg's) which is half of what I am thinking. Or maybe this person already added the BA to the IGF vial, which diluted the potentcy. I would greatly appreciate any help.

lab-corps (and most IGF) is sold ina concentration of 1mg per ml, which would workout like you stated 4IUs 40mcg.

Mine is 500mg/ml, thats why my 10 ticks is 50mcg. Your right on bro.

Thank you for the help, I appreciate it.
