Can you buy over the counter HGH?

Excuse me, I'm curious about something. I've heard about HGH, and I'm wondering if it's possible to purchase it over the counter? I understand it's a hormone that's naturally produced by the body, but I've seen it advertised as a supplement or treatment for certain conditions. So, is it legal and SAFE to buy HGH without a prescription? Also, could you elaborate on the potential risks and side effects of using HGH without medical supervision? Thank you for your time.
