I have read a lot of info on IGF1-related cancer risks see: [ame="http://www.google.com/search?hl=en&lr=&ie=UTF-8&q=Cancer+and+insulin-like+growth+factor-1&btnG=Search"]Cancer and insulin-like growth factor-1 - Google Search[/ame]
The only thing I haven't been able to find out is if this applies to cycled administration. Most of the studies seemed to be conducted on persons who have elevated levels not due to IGF1 usage but from genetic disorders. To me, that is due to long-term elevated levels. Since most IGF1 cycles are 4 weeks in duration and natural levels return soon after I do not know how relevant these studies are to bodybuilders.
Anyone else have any ideas or observations?
