Sure, your alcohol will be just fine.
Are you diluting by weight?
I've never actually diluted everything I own. But if doing so helps, then by all means!
Pretty much, the "C" aldehydes should be diluted, simply to work with, unless you are trying to overdose them on purpose.
And certainly the Indole , and if you are diluting everything else, than you better dilute *all* of your materials to learn with.
After you learn the materials, you may not need to predilute all of your materials.
