IGF-1 doses and specific protocols of use is a bit of a controversial topic in both the medical and performance enhancement community. In a therapeutic setting, IGF-1 doses will normally fall in the 40-80mcg ranges and may be given 1-2 times per day. This is undoubtedly a large, very large dose, and it can be hard to control for some when we consider hypoglycemia. Most physicians will not have the individual start above 40mcg and levels will be monitored closely. Dosing may be increased by 20mcg if needed but will not surpass 120mcg for any reason as this will be extremely difficult to even impossible to control regarding hypoglycemia.
