It’s probably particle size since caffeine and more so theacrine have a bitter taste and also creatine does taste slightly bitter. Especially caffeine and theacrine are not easily soluble in cold water and therefore, smaller particle size greatly increases speed of dissolution. A finer ground powder hence dissolves faster and therefore tastes more because only dissolved substance can be tasted.

How is your blend prepared and consumed? I mean, does it have to be dissolved in water or fruit juice right before use?

As challenge test: Dissolve each a hand made sample and a machine made one in hot water, stir until everything has dissolved, let cool to drinkable temps, and only then try both. Is there still a difference?

The blender they use is a v blender. The mixture is used by adding it to water and mixing before drinking.

Is it heated? Heat will affect flavor depending on how long/high it is heated.

What is the mixer machine made of?

The part which I’m struggling to understand is we had the product tasting great when in a hand sample but when scaled up and put through mixer this bitterness just appears.

The mixing process is does not use any heat. The ingredients consist of a mixture of nootropics  and stimulants. Without publishing all ingredients it includes things like caffiene, creatine, teacrine.
