Hgh does not work locally.
IMO most compounds that people say work locally anecdotally also don’t. Bpc for example will work fine pinned anywhere.
Continue as normal and train your arms
BPC exerts its effects by existing in a location of injury in large quantity, the same with many peptides with "healing" properties. GHKcu is similar in that regard, but obviously different effects; of the many things that it does, it acts as a beacon for damaged tissue and attempts to put it on your immune system's radar, and one of the methods that it uses to do that is via pain. If you pin GHKcu near a wound, or zit, etc, @ 2mg or more, the wound, zit, etc would feel like a gunshot wound. So lets say that was on your right leg. Now if you pin 2mg on your left leg, the right leg's wound or zit will not have the same response. Even hours after it has gone systemic, the wound on the opposite side will not throb with pain.
Now let me be clear. I am
not saying that the GHKcu would not go on and act systemically and eventually provide some effects to the damaged tissue on the opposite side of the body as the pinning location. What I am saying is that, since GHKcu is a peptide that exerts its effect by congregating in one location more than another, pinning near the intended location will ensure that, even for the briefest moment, more of that peptide will have congregated there, and a more dramatic and targeted immune response will occur. The same thing stands for BPC. There is absolutely no literature that exists for that since it has no study has been designed to test it, but I am certain. I have stuck more of this shit in my body than anyone else.
No idea about GH though, i thought GH exerts its effects through the IGF1 axis, so prob not the best bet for local pins.
