Hi Adam,
The fact not even the rep of the product can tell you how much caffeine in it is a bit of a worry. 100mg sounds about right, however this is a very mild dose by supp standards, many are in the 250mg + range of caffeine per serve.
As I mentioned, Caffeine is much much cheaper than DMAA, so the likiehood is that caffein levels will be bumped up and DMAA down.
The differences between the Bulk Nutrients and Bioflex pre workout products are a few. I did a large analysis between the two and jack3d on another board, I will re post it here.
