Update: I'm still taking the 5,000/1,000 L-Arginine/L-Citrulline combo (http://www.amazon.com/gp/product/B00D94CIC2/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
). I still get good results out of this combo. I think getting enough essential fatty acids is also important. I can go back on fish oil - at times after I've run out of my supplement combo a few days - and suddenly, WHAM, I'm getting unstimulated erections that are very obvious that something is the catalyst. I can guarantee you that the L-Arginine/L-Citrulline combo's efficacy is definitely NOT a placebo effect. In fact, when I run out the much better wood will linger a few days and then I can tell I'm not getting nearly as stiff. Back on the combo, about 2 - 4 days - WHAM, I'm back!
But you guys got me to thinking. I do believe that the L-Arginine may cause me some occasional bloating. I wonder if going to just an L-Citrulline powder, but increasing its dosage, might be as effective. I never tried over 3,000 mg/day of just the L-Citrulline. I tried the combo because I'd read where that might work better (the two ingredients in tandem). It sure seemed considerably more effective - and it's continued to make a big and CONSISTENT difference. I may experiment and try just the L-Citrulline powder at, say, 4,000 mgs/day. My blood pressure is not an issue with the L-Arginine - as it's excellent. Plus, I've lost 43 lbs. since last August. However, if I find that the L-Citrulline alone, at a higher dosage, is equally effective, I may just stick with that instead. Plus, the L-Citrulline powder is a good bit cheaper than the combo powder.
I'm a bit concerned with the occasional bloating, as I've developed an inguinal hernia
, which bloating can't be helping.
