I'm just going to throw this out there, but if the results of Beta-7 are comparable to Creatine, and the cost of Creatine per month is roughly $10-$15, and the cost of Beta-7 per month is between $50-$150, which supplement do you think people are going to put their money towards?
You potentially could have Alpha Male and Creatine for less cost per month, and while I know that they don't both work on the same level, I'm willing to bet that the combo of Alpha Male and Cr (or Carbolin 19, Surge, and Cr, and...) is as good or better than taking the Beta-7 by itself at the highest dose.
Again, I don't know first hand, but I'm just going by what I've read and I'm sure others have run these sort of same comparisons in their head's before choosing to buy their next round of supplements.
Unfortunately, I wasn't financially ready to purchase supps when the Beta-7 and Cr offer was out there, however, if the goal is to get people to try, maybe that should be a continuous offer for a little while longer. If that deal was out there now, I'd certainly buy and try to make my own decisions about how effective Beta-7 is for what I do.
I know because I'm a bigger guy, I'm going to be on the max end of that dosaging, and $150 a month is a pretty stiff trial period, IMO.
