No, but I wouldn't want to. 
I have been able to create stones that are too strong for my daily use. An emerald charged with love so powerfully that it overwhelms my energy body, and all of my energy rush to burst open my heart chakra, and leaves me shaken afterwards. 
A stone that is too strong is no good. If the vibrations are too much stronger than your own, the stone is not usable, and creates fear in all who encounter it. 
There are horrifying stories of people who ingested a tiniest piece of their own philosopher's stone. 
I have had a similar experience, although weaker than those famous stories, of creating a powerful tincture that was far too strong and having an uncomfortable time where my heart chakra was blown open to extreme sensitivity for about a week just from ingesting the tiniest drop.
You can make safe and steady spiritual progress in alchemy with just weak tinctures. Making them overly strong just opens you up to having a bad time and becoming afraid of progressing further.

Might you happen to have a comprehensive list?

Do you recall them?

Was it a spagyric?

Have you tried vitamin K2 supplementation? You might have calcium shell syndrome. The calcium shell acts as an amplifier to emotional energy waves within one's vicinity. Calcium shell syndrome can lead to emotional issues. Especially in highly sensitive people (HSPs) or Empaths. Vitamin K2 mitigates the hypercalcemia that causes calcium shell syndrome. By any chance, have you been experimenting with dry fasting? Because hypercalcemia is one of the side effects.
