Also keep in mind that the new GH compounds available are premixed and stable at room temps and higher for years. I had Norditropin sp? pens with the cartridges you load into them. Premixed and stable for travel in temps upto about 90 Deg.
Most old fashioned dry powder should be refrigerated asap BUT it “MUST” be refrigerated after mixing.
I recommend the Premixed newer generation of HGH.
