When I'm asked about GH dosing protocols, here's my typical advice. Based on my experience personal and with people I coach.
2iu - basically useless imo
3-7iu for quality of life benefits such as improved sleep quality, recovery, skin and hair quality. Some lipolytic benefits.
8iu+ is where I see the body composition benefits start to become more pronounced. This is where overtime you'll start to notice yourself developing the round, full, bubbly bodybuilder look.
Storage doesn't really matter as far as I know, I store mine in the refrigerator.
In terms of dosing timings, in a fat loss phase I believe it's best to take an AM/PM dose to maximize your exposure to the lipolytic benefits. In a growth phase, bolus dose before bed seems to be the most favourable for managing blood sugar.
Some of the acute effects I notice is improved sleep and some fullness in my physique. Long term effects are the body composition benefits I mentioned above. Along with some undesirable ones like facial bone restructuring. I look like a fucking neanderthal now lol.
Run it until the day you die if you can afford to do so. No reason to come off. I will adjust my dose throughout the year depending on the goal though.
Only advice I have in regards to using GH is to keep on top of managing your blood sugar. Chronically high blood sugar will have you spinning your tires big time in this game. And of course the health implications of high blood sugar.
