Correct me if I'm wrong 1mg = 1000mcg = 100 units and 2 units = 20 mcg. I have 29g .5" 100 unit slin pins. Does that mean that I only draw out to the second mark on the pin to make 40mcgs? I've never used IGF-1 or growth so it seems like nothing compared to a 1cc shot of AS. If this is correct would It be better to use .5cc slin pin?
