"attenuation" is the term
I think you got the Gen 2 or 2.5 version which were pretty good in not getting used the effect but not perfect
the Gen 3 version now out ( just released less then 2 weeks ago)
has almost no chance of attenuation do to the high end performance load through multiple pathways of stimulation ( both via CNS, pro pump, strength and endurance compounds)
in other words Gen 3 Amplify 02 used for Lifting has almost no chance of getting old.
PS: take Amplify 02 with 1/3 of an apple from now on,
we discovered it is the best "carrier wave"
for the product which also amplifies its power by what seems to be 20%
