not really its the Niacinamide
Niacin is nicotinic acid which is generally not well tolerated
Niacinamide is nicotinamide which is tolerated much more widely but may still cause a flush which is very Uncommon but can still occur, it is generally considered "NO FLUSH" niacin, so much so that it is used in the FOOD industry as a fortifier.
Then we have inositol hexanicotinate it has almost no possibility of flush but also feels rather inert in formulation and does not give that energy we seek
if we disagree then thats fine
having sold MANY units this has been the consensus that has been found that its the Niacinamide
also another company uses Niacinamide in a preworkout products and it had the same effect for some just as Amplify02 does for some as well.

Blut it pretty well known that this can occur so if it new to you now you know
no biggie.
And I also glad this post was made so people can be aware of this very UNCOMMON occurrence and how the minor addition of food and extra water may solve it.
that all I have to say on the matter and you may PM if you want to "talk" more
