Hgh and Cancer. Storing Mixed HGH. Myths or Real Deal?

So I have a few questions about HGH. I am very curious about two things. Cancer and Storage. Starting with Caner. I see lots of stuff talking about it but yet after weeks of looking for studies or evidence I’ve yet to see any evidence. Any thoughts?

Second is about storage. Want to get confused google that topic lol. Storage after mixing with sterile water I get but what about before? Some say yes some say no!!! Help me if have any experience
