In terms of it's use in bodybuilding I have never heard of any sides when compared to androgens or anabolics as IGF-1 does not disturb the HPTA....
currently many people are seeing localized growth with site injections of Long R3 IGF-1 but those results are short lived. there should be an oral version of IGF-1 available soon but I have yet to see any data on it's effectiveness...
