I am only going from a couple of guys in the gym who swear by this stuff but the new Testosterol XP stack I hear about, seems to be a lot more potent than your 100mg andro supplement. It has 375mg of a combination of 1Test-ether, 1-4AD, and 4AD. It also has Tribulus (>40% saponins), and L-glutamine.
From what I've seen in results at the gym, I am going to try a bottle for 1 month and see what happens. I'll post results here.
