Actually, it is 1 ml = 1000 mcg or 1 mg. Most people use anywhere from 30 mcg to 60 mcg / day. A normal cycle is usually 4 weeks on, then 2 weeks off, then start again. Depending on how your body reacts to it, you could even go 6-8 weeks. (I'm on my 6th week now--2nd cycle--and the stuff is still working great.) Others find that it stops working after 4 weeks.
IGF isn't like AAS, so you shouldn't expect a huge weight increase. Normally, you'll decrease fat and increase LBM so that you'd stay at or around the same weight. Make sure you eat very well.
I'd say with your stats (seems that you have a slim build for your height) that you'd benefit a lot from using IGF.
