Bodybuilding.com has pulled the sale of these two Species products so there must be some kind of weight behind his statements.

bb.com just don't need the bad press right now, my guess is they can do without 1 or 2 products.
Overall I am not 100% convinced that this product alone contributed to liver failure, I would highly suspect she has taken other enhancements but of course I don't know the person.
Overall I have (for a couple of years) given up completely on all nutritional products, I simply don't trust them enough to justify the money spend, I also think it would be rather selfish from myself to spend money on overprized products that have little to no value especially since my baby should be born very soon (touch wood).
Overall (and I only talk about myself here) I have seen way more strength gain and overall quality of lifting when I stopped taking these products all together, and I cannot really recollect any real advantages of all the amino acids and or protein and creatin I used.
I'm sure others have I just say I never have for myself
