Before I google this beta stuff, in your words, describe it for me. That sounded retarded but I'm serious; I like getting first hand descriptions from people I trust rather than reading some other crap.
Basically it actually did for me what creatine was "supposed to do." I never really noticed any direct effects from creatine other than power-of-suggestion. So I substituted beta alanine for creatine after researching them technically. I take it before sessions. And it really does work. And it's about the same price at GNC, dose-for-dose, as creatine. For me, I noticed 2 things:
1) Increase in power. Now I typically am a mass-builder, so I don't powerlift all that much. But I occasionally will try and max out on the power/oly lifts. And as cheesy as it sounds, I just feel like I can "harness power" a lot better on this stuff. Like, with lift, clean and jerk, before I always felt like it was a strain on my body, struggling and such and not rewarded. But now, it feels like a good burn, almost like a "omg I need to lift this car, my child is stuck underneath!" feeling. Raw power.
2) Just an overall focus in the gym. I can now push workouts to 25-30 sets without the last few exercises feeling compromised. I feel pumped for sessions. Increased temporary endurance.
In general, I feel like it's the real deal, something that all of the pre-workout pumps are trying to reach for (god the name of the infamous one is on the tip of my tongue - pink bottle). I don't feel as if I've lost any mass from quitting creatine, but I have gained power/endurance.
Now I am settled into:
Protein
Ammino Complex
Beta Alanine
Glutamine
Vitamin
Magnesium
