I am with Ehren, having a 5 - 10 year supply laying around is a horrible idea IMO.
Also, hgh has a shelf life of about 2 years from what I understand. Subtract the fact that your hgh is UGL and probably at a higher risk of degradation than pharm grade, subtract some time for the varying degrees in your fridge not keeping it at a steady 33 degrees, and then subtract the unknown amount of time it has been sitting with the manufacturer, and then with at least one supplier from how long you have had it and you would be lucky to have potent hgh at the 18 month mark.
My dream stockpile is a plethora of interest earning accounts, allowing me to sit on my ass all day and get paid well to do it. That and probably a bunch of guns, cows, land, and gold.
