That’s your choice and others as well. Personally I am not willing to risk my own health on that gamble.
They have sources jump through hoops to protect their members and it’s the sources choice to try to sell their or not. They set the rules to sell and if they don’t provide what’s required then they can get flamed and go elsewhere.
Regarding Iron Lion on Meso you can see some people did vouch for his HGH but he did get flamed because he also didn’t provide what was required many times. So that’s on him and not the forum. It’s free to post there so the least they can do is provide what’s required to post there or go elsewhere. He also didn’t do well there because his prices where higher than TP and Opti who both sell high quality HGH with hundreds of great reviews over there for less.
