The point was I don't need a clinical study - it works for me. I run it from time to time on certain cycles and it's beneficial. What is really wild is hundreds of other members on this forum, and hundreds I've met in real life have had the exact same experience. And it's never taken months (like you claim: "You need to be on proviron at least a few months to even to start noticing the benefits") for anyone I've run into. You're just wrong, move on. Happens to all of us.
Cialis and Viagra work great - I respond well to both. When I am not running tren or deca only use them sporadically for fun. Arginine relaxes blood vessels - citrulline converts to arginine. 1 + 1 = 2. May not have much of an impact on some, but it does on others. Try it if you want, if you don't - don't. The beauty of a forum is real user feedback - I shared mine. If yours is different that is ok
