Depending if you are taking it by injection or orally you are probably seeing the effects of basically an overdose that is common when you first get on hGh. What has been recommended is to start drinking more water with each injestion of it. Drink like 16 oz each time. This dilutes the solution and you body should respond well after a while. if you still see same symptoms you should probably back off on the dosage and if that doesn't work you might want to see a doctor to figure out why.
