Excessive Experimentation
Perform alchemical research or experimentation 100 times.
Excessive Experimentation requires you to perform alchemical research or experimentation 100 times using the Dragonflight alchemy experimentation recipes.
Open Dragonflight Alchemy Tab
In your Dragonflight alchemy crafting window, navigate to the Alchemy Essentials section. There you will find four recipes that count toward this achievement: Basic Potion Experimentation, Advanced Potion Experimentation, Basic Phial Experimentation, and Advanced Phial Experimentation.
Experiment 100 Times
Use any combination of the four experimentation recipes until you reach 100 total experiments. Note that Secrets of Draenor Alchemy experimentation does NOT count toward this achievement.
Manage the Cooldown Debuff
Each experimentation applies a 2-hour debuff called Recent Catastrophe that prevents you from experimenting again until it expires. Using 
Liquid Courage or 
Formulated Courage will immediately remove this debuff, allowing you to continue experimenting without waiting.
Tips
Experimentation results also contribute to separate alchemy achievements for potions and phials, so each experiment counts toward multiple achievements simultaneously.
