specifically 5-DHEA or (regular) DHEA is not subject to the new law.. however the ones with any action are considered fair game.
regular DHEA is pretty much benign, in that it really doesn't convert into any thing appreciable, therefore they will leave it alone because its widely accepted for use in the anti aging industry.
these others DHEAs are specifically modified in a lab and fall into the designer class. also you will note these are specifically tailored to anabolism/muscle growth. they likely have no other legitimate use, thus making them fully susceptible to the new law.
