Do GH and IGF-1 attach to the same receptor(s)? I ask in terms of rotating injections when using both. If they are the same receptor, then pinning the same muscle too frequently using both would down-regulate the receptors. If not, then you can for example put IGF in your biceps one day then next time GH.
Also, related, I know you shouldn't use IGF more than once a week in a muscle, but does GH have the same problem, or can you use it frequently in the same muscle?
