What is the new growth hormone drug?

Excuse me, could you please elaborate on the new growth hormone drug? I'm curious about its purpose, its mechanism of action, and if it has been thoroughly tested for safety and efficacy. Additionally, I'm wondering if it's a prescription-only medication, and if so, what conditions would it be used to treat? Lastly, I'd like to know if there are any potential side effects or drug interactions that patients should be aware of before taking it.
