Ok so I've used ArA for a very long time (like most people on here have). I've used MassMax xt solo twice (I think) for 8 weeks and AlphaMax xt 3 times for 8 weeks. I've stacked all 3 once and I've used ArA with MassMax xt and ArA with AlphaMax xt once. Currently on my second go around with MassMax xt and ArA. My goal is pure mass and it lives up to the hype. Tons of logs, both sponsored and unsponsored, showing that it works and works well. All of the logs have very similar results also. The addition of ArA just makes MassMax XT so much better. It's hard to explain but I just don't want to stop lifting and eating. MassMax xt can/will increase appetite hence the weight gain. But even if you don't eat more, it can still add some pounds on you. I tested it this way my first time using it.
AlphaMax XT, for me, is best used on a cut or lean bulk/recomp. It really helps with changing my physique. Nothing crazy but combined with a proper diet and training routine, you really reap the benefits it has to offer.
