So Bill, if X Factor is that good, why has it not taken off despite all the pro hormone crap out today?
Would you also agree that most of these little pro hormone companies are putting out crap products, most not even having the dose they say is in their product causing more damage than good? Not beating them up, but you obviously have inside info.
What dose do you suggest for X Factor, not for financial reasons, but for effectiveness. It is pretty pricey ya' know 
I wouldn't at all say that it hasn't taken off. Admittedly it was a long hard road for arachidonic acid, as would be expected for any new nutrient coming out with strong claims of strength gains, fat loss (body recomp really), and muscle growth. But after several years we're finally selling well, mainly based on word of mouth referrals from consumers. We have also licensed the product to 6 other companies including Gaspari, Universal, IDS, and Axis. So all in all I believe we are well past the tipping point for AA. The nutrient does work very well.
I do have extensive experience with prohormones, which come from the same supply channels as the present designer steroids. So I can give you my .02. I would agree that you have to be careful about quality control and testing your raw materials with steroid products coming from China. I think there are many companies that do this rigidly, and others that don't. So you will have a variety of perfectly dosed products, underdosed products, and products with ingredients not listed on the label out in the marketplace. The phrase "cheaper isn't always better" probably applies to some extent.
I still recommend 750-1,000mg of X-Factor (3-4 caps) per day for optimal results. If you want to experiment without a 2 bottle investment though, try running 500mg per day during a period when your training is very stagnant. You should be able to make good progress on this, which is half the max dose. I don't think the price is all that bad considering you do not need PCT, and the gains are strong and well retained. But admittedly in the face of cheap highly potent synthetic designer steroids it might not be the first option that comes to everyone's mind - but we're getting there.
