Interesting.
CM2:1 is pretty tart, so how does it impact the taste of yogurt or a shake?
I'm like Vince in that I love the taste. It makes everything tart and I look forward to it. My yogurt is plain and it would be pretty bland without it.
In a shake, it's the first thing I have every day and in yogurt, it's the last thing I eat at night. I put vegetables in my shakes and that CM really make spinach, kale and/or broccoli palatable.
Also, like Vince, I'm a bit older (53) and maybe I need it a little more than younger folks AND, similarly, I have gone off for a few weeks and noticed a marked difference in pumps/vascularity, erection quality and recovery time.
Vince also got me taking Norvaline which has increased the effectiveness (either on its own or in conjunction) with the CM. I was not sure the Norvaline was working so when I ran out a few months ago, I quit taking it (it's expensive). After a few days I felt "off", NO-wise. I ordered some more and I returned to pre-cessation levels. I will not take one without the other now. (I also use beta-alanine in the shake and take pycnogenol, plus a few other non-NO powders)
Unlike Vince, however, I do not take CM/Norvaline on an empty stomach. I really cannot think of a Rx (cialis, levitra, viagra, thyroid, cortisol, etc) or supplement that works for me better on an empty stomach (*shrugs*)
