I've been chatting with geo recently to see what kind of business he runs and kinda get a feel if he may be or has been pulling one over on his customers and eroids. In my book he is is a stand up guy, and I've never had any problems in the 3 or so yrs I've used him. I mentioned to him he should get YK 11 and sure nuff a few weeks later he had it, and even sent me out a test run sample for my subjects, after he had it tested. Guys if you get a chance, give this SARM a shot, it's a myostatin inhibitor and it's affinity to bind to AR is greater than DHT. The result of this is great pumps during workouts that last all day and lean mass gains. I am very pleased with the results this SARM brings.
