I use kigtropin now but before i used blue tops i got direct from China and i had the same effects as you at the same doses, a lot of good blue tops around, if you have a good source they are good to go 
How long does unmixed HGH last unrefrigerated before it's start to degrade? I've read very conflicting views.
"The only GH that does NOT need to be refrigerated before mixing is Serono company. They hold a patent on a strain cultured from a different cell line of mammalian cells that makes the GH more stable in it's dry form. Lilly, Novo-Nordisk, Genentech, and our Somaject DO need to be kept refrigerated at ALL times.
Generally speaking the GH will remain stable (as in not losing ANY bio-activity) for around 24 hours depending on conditions (heat, humidity, and light).Next day air shipment is recommended, especially during hotter
seasons to avoid any loss of bio-activity.
HGH, when stored in a temperature of 2 to 8 degrees centigrade can last up to 20 days. After you purchase the HGH vial, store it in the refrigerator at this temperature range. Even if you have used it, HGH usually lasts as long as 20 days at a temperature range of 2 to 8 degrees centigrade.
Undiluted, freeze-dried HGH powder in sterile vials may be safely kept at room temperature, not to exceed 86 degrees Fahrenheit, for up to 18 months (as dated on each vial). Up to 110 degrees for a day or two before mixing may be tolerated without a problem. Once diluent is added, however, the resulting liquid HGH must be kept refrigerated and used within 4 weeks or potency will slowly decline." - Dr. Elmer Cranton
