JeffK any suggestions as to names/brands.
Long story on possible causes. Getting off (no pun intended) depression meds are helping. Working with Dr. for low test. Injecting test e 50mg every 3 days but had this issues for a while even before low test issue.
I get nice hard ons but they seems to loose there hardness as time goes on. Even if Im watching porn.
It works and all but it goes from rock hard to just ok hard.
For Arginine/Ornithine, NOW has a product that works good, is cheap, and an easy way to see if it works for you. I think it's something like 500mg Arginine and 250 of Ornithine or something. I usually take 8 or so before a workout.
I have a sample of Aspire36 I've been dying to try, but haven't tried it yet.
I'm also on testosterone replacement, and use Dr. Crisler's protocol, for me, testosterone cream daily and HCG injections every 3 days. If I miss an injection, I feel a very noticable crash on about the 5th day. The HCG helps with testicular atrophy and keeps drive and such going. It might be helpful in your case, you might wanna chat with your doc about it. Dr. Crisler has a writeup about his method you can give to your doc that's extremely good.

I find that I'm in a pretty good niche now in terms of sexual function, with 10mg of test cream a day, 250-300 iu of HCG every 3 days, and I use White Flood before workouts. Between those, I'm good for a couple really good loads a day and rock hard hardons. Wifey isn't complaining
I had low test and low thyroid due to chronic lyme disease, so that's my story, not sure if it will ever improve though, won't know until the Lyme is erradicated, and I'm getting there but it's slow.
Good luck...
