Should HGH be refrigerated?

I understand that there are many concerns surrounding the proper storage of HGH, a hormone used in medical treatments. My question is, is it necessary to refrigerate HGH in order to maintain its potency and effectiveness? If so, what temperature should it be stored at? Alternatively, are there any circumstances where HGH can be safely stored at room temperature for short periods of time? Additionally, how does improper storage of HGH impact its overall quality and performance?
