Suppose you have some? Do you have some or not? And if so, is it in powder form? Or is it already reconstituted?
Either way, I would add 1ml of solution so you can use less volume. What I do is this (this is using 100mcg/d):
Draw out 10iu (100mcg), then draw up the rest of the syringe with Bac Water to ensure I get a good mix and get all the IGF-1 out of the syringe. Then use it PreWO in the muscle group being worked. Good stuff. Obviously I wouldn't start this high at first if I were you, so if you do 50mcg/d, you would just cut that dose in half.
