It’s a matter of what one is used to… I remember I used to think BCAA’s were really nasty, but by now they, or leucine by itself, are only very moderately in the off-taste category.
Added to something else that is tasty, they still do a good job of damaging the taste of whatever the other thing is, but by themselves, no biggie.
It may take a couple of months, as a guess, to acclimate.
