I am not familiar with chinese gh, but I have read that Serostim (somatropin(rDNA origin) for injection is a human growth hormone that is very effective. After reconstitution with diluent it lasts 24 hours. The reason is because sterile water has no antibacteria. If you want to have a longer shelf life use CYANOCOBALAMIN Injection 1000 mcg/ml. This is a vitamin B which contains an antibacteria which will make your gh last for as long as you need it to last. Hope this helps.
The best place to inject it is sideways pinching around your abdominal area, with an insulin syringe. The reason you inject it sideways its because it needs to be injected between the skin and muscle so that when you are done you will see a little lump.
