So i'm intrested in saline injection. I currently have around 10-12 1000ml sterile bags of normosol-r, being used for other purposes. Normosol-r is a saline solution combined with some essential minerals and electrolytes. More info here: Normosol-R Official FDA information, side effects and uses. What i'm wondering is if this solution is safe for human subcutaneous injection into the scrotum. Or if this will cause any negative unwanted side effects, I have all the sterile supplies I would need, tubing, needles...ect. Also, is this safe for injection in large quantities, eg: 700ml-1000ml? If not I could just go buy some bags containing only saline.
