I've searched all the web without having a definitve answer.
Basically it seems that DAA bulk products are D Aspartic acid.
Others products are Sudium .
I understand than the Sodium one is more soluble, but it seem that feedbacks from people using DAA in Bulk are less "Enthusiast" than the ones that uses the sodium D-aspartatic form.
SOmeone says that you have to use more (even 2 x) DAA bulk to have the same effect, someone says that it needed only to add some Bi-carbonate of sodium to the bulk to have the same effect, someone says to use more water (even 1000 ml for 3g of Bulk DAA), someone says that the bulk DAA is in real "only" L- aspartic form, someone says to puth in mouth and drink a glasss of water only.
Someone says that the DAA Bulk it's tooo acid to be absorbed by the body, someone says that they are the same.
Soeone says to warm the water to be used to let it go in solution, someone says that it need to be ice-cold.
I repeat: I'm lost.
