I have some arginine/citrulline combination, 22mg per ml of each, for injection. I want to take it to see if it helps with erectile dysfunction. So, how much and how often? Does it have to be daily, or can I for the sake of convenience inject it on the 2 days per week I also inject testosterone? I also take 5mg of tadalafil twice per day. Thanks.
