The general consensus so far is that new ABE is as good or better than the old formula. New EPro has positives and negatives in that fewer people experience joint discomfort, but it seems to take a little longer to kick in and some people report a less-noticeable drying effect from it. I will keep looking at what people have to say since the real feedback will start coming out in the next few months, but it seems like the new Epro was designed so that everyone can use it since arimistane was really rough on some users' joints.
I would take all of the "the new formula sucks compared to the old formula" talk with a grain of salt, since people say that about every new formula of every product at first. Realistically, if the old EPro was perfect for you (no joint discomfort, crazy leaning/drying effects, libido boost or at least no libido damage) then it might be hard for the new formula to surpass it (it's hard to improve on perfection), but if you had any undesirable sides from the old formula, then the new one might be great!
The original version of EPro had people all over the map, from those who got nothing but side effects, to those who loved it more than any other supplement. I'm sure some people will love the new one and others will hate it. If possible, please report on how you feel from the new one compared to the old one.
