I've seen a lot of questions on solubility of noopept, and some on its biodegradability. Here's a paste of the info and source at bottom

It's going to hit water in your GI tract anyways. That is why I tell everyone to use it subligually. The faster it hits your bloodstream, the better. Dissolving it and drinking it should not lead to much more degradation than what will happen anyway in your GI tract. Dissolving it in water, then storing it, will.
