IGF-1 and Similar Products

So I have been doing a little research on these and when first reading some of the clinical studies specifically by Dr Sweeney i was really excited about them but after looking further am just confused you see in the clinical trials on mice the drug was injected directly to the muscle mass to help stimulate muscle growth and to protect the internal organs but when searching for the product it apears to be taken oraly also i cant seem to find any clinical test results on humans where IGF-1 has been directly injected into the muscle mass so what is the truth on this is it any use or is it just a fad product where the marketing came first and the science later.

You need to start supplementing with a few of these first:


Fair enough but you got any real advice.
