The source I use has a Telegram channel. I went to the channel and asked if it's safe to buy liquid HGH considering the current summer temperatures. Another user posted a lab results of liquid HGH that was transported from the UGL's warehouse to him, from him to an analytical lab, and from the analytical lab back to him.
Dosing and purity were the way they should be. So, dosing was correct, indicating no degradation and loss of HGH occurred.
The tests were legit, not faked.
I have already ordered liquid HGH. When I receive it, I will inject it, wait 2-3 hours, then go to a lab to get a blood test and see if the expected dose-dependent results in terms of GH levels are present. If they are present, then I will assume no degradation has occurred to the HGH.
