My man. You bought this without knowing anything about it. You need to research some more. I'll give you some advice. 15mg is a big bottle. It usually comes in 5mg. 1st you need to use bacteriostatic water which you can purchase from any research chem company or make it. Don't use regular water unless you are trying to get an infection. Google peptide calculator to get the dosing and mixture correct. Most people use 100mcg three times a day but most use with a ghrh like mod grf or cjc for best results. Start at 50mcg just to see how you respond. After doing more research I will help if you have more questions. I'm not sure how long ghrp6 is good for after reconstitution but 15mg seems like a large amount for 1 vial.
