Here it is. Something I found about Dynamine
Quick Summary Points
Dynamine or Methyl Liberine is a pure alkaloid compound structurally related to caffeine that functions to boost energy, focus and mood
Naturally found in a variety of coffee species
Commonly found in pre-workouts or fat burners in its trademarked form Dynamine™
Possesses similar physiological properties to caffeine
What is Dynamine?
Dynamine, also referred to as methyl liberine is said to be a rapid-onset, high impact ingredient that functions to boost energy, focus and mood. Dynamine is considered a pure alkaloid that is naturally occurring and fast-acting. It is in the methylurate family since its molecular structure is closer to theacrine (aka TeaCrine) than to caffeine. While there is insufficient information regarding this ingredient at this stage, it is showing promising properties as a high-stim pre-workout ingredient in supplements.
Where Does Dynamine Come From?
Dynamine or methyl liberine is naturally found in a variety of coffee species including Coffea arabica and Coffea canephora (robusta), from coffee beans that produces minute amounts of methyl liberine. Methyl liberine can also be found in caffeine-containing beverages such as tea, guarana, yerba mate and cocoa. In addition, studies have indicated that methyl liberine can also be synthesised particularly from green coffee beans.
Dynamine Side Effects, Negatives & Safety
At this stage, we expect that dynamine poses similar side effects to caffeine or theacrine. Like theacrine, methyl liberine is believed not to raise heart rate, and to improve feelings of energy, mood and focus by activating dopamine receptors and inhibiting adenosine. While most stimulants can offer positive benefits, it also comes with its share of negative effects, which vary by dose and by a person’s tolerance and sensitivity level.
Let's wait and see how this turns up to be.
