I used GHB 1,5 hours ago, but don’t feel much. How do I redose as safely as possible?

Make sure that when you redose, you know exactly how many milliliters you are taking by, for example, measuring it with a small plastic syringe with the milliliters written on it. After your first dose, there is always a residual amount of GHB in your body, which increases the risk of overdose. This is also known as the stack effect. So do you still feel nothing after 1 or 1.5 hours and do you want to take more? Then do not take more than half of your first dose. Then wait at least another 1.5 hours to see what this additional dose does to you.
