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.
