So you don't agree that with rhIGF-1, which has a half life of about 15 minutes, and when we get a "pump" the IGF BP binds that immediate supply of IGF to the receptors in that immediate area where there will be muscle repair? When site injected, there will be more binding, and that's even the case with DES, where the receptors that have been damaged or misshapen by LA will still bind with the 1,3 IGF. Study or not, its common fact that this process will happen. Now in the case of Lr3, yes... injection even IM will enter the bloodstream and bind with receptors all over the body, but we still have to think about immediate availability, especially after a workout. Just food for thought
Again, you tear your bicep. Where are you going to inject IGF? your calf or your bicep? Hypothetically, two people with the exact same genetics, exact same body both tear a left bicep. One injects into the calf, one injects into the injured bicep... whos recovery is going to be better? I'd bet my left nut on the guy injecting into his bi.
