Wow, someone asked the question I have been thinking about for the last couple of weeks. I take a lot of protein supplements and vary out what vitamins/amino acids I will take throughout the week. This question has prompted me to go out and read up on other things. I never take ginkgo, but it has been bouncing around my brain that because of what it is known to do, help vascular recovery, I thought that it would be perfect to start using in PE.
I am interested in reading up on what you brought up Gold_member; about collagen. As for glutamine, I think that would help. Creatine no.
