Great exchange on all of these topics. Back to the individual labs that we call our own bodies, I have to say the POM juice has had a very noticeable positive effect for me over the last three months. In reading further on these few threads, I have added more nitrate friendly veggies multiple times per day when possible. I cant eat a whole bag of arugula like Peak T, but I try. Lately I have added 1.5g of Citrulline and grape seed extract pill (subbing in for Pycnogenol). I would agree with the one comment that if your anxiety/stress levels shoot up, or sleep is disturbed, this protocol cant overcome it with immediacy of Viagra/Cialis. However, on a regular basis, I have noticed a big difference, especially overnight and in the mornings. FYI, I drink 4-6 oz of POM brand with my breakfast. I think it tastes great. I basically substituted the POM for Orange Juice, which has about the same sugar content. FYI, where I live, you can get a 2 liter (app.) bottle of POM at Sams for around 9 bucks. Not much more than OJ. I have tried some other brands of "100% Pomegranate" juice, and they all seem watered down compared to POM.
Bottom line: this site is the best out there for guys that care about their health in middle age and are scientifically minded enough to get it. You have to be willing to try some of these things to see what works. Thanks to Peak T.
