The reason your fat-burner felt incredible in week one and ordinary in week five is receptor biology, not a bad batch.

How tolerance develops
Regular caffeine exposure causes the brain to upregulate adenosine receptors. More receptors means the same dose blocks a smaller proportion, so the subjective lift fades. This happens within one to three weeks of consistent daily use for most people.
What fades and what does not
The subjective alertness and the thermogenic bump attenuate substantially. The ergogenic effect on exercise performance holds up considerably better, which is fortunate, since that is where most of the practical value sits anyway.

Get SodaSlim — From $49Why escalating is the wrong answer
Doubling the dose restores the feeling briefly and then tolerance follows again, this time with jitteriness, poor sleep and raised resting heart rate for company. The ceiling arrives quickly and the side effects arrive first. A fixed single daily dose, as in SodaSlim, avoids this trap by design.
Cycling, if you want to
A deload of one to two weeks at low or zero caffeine restores much of the sensitivity. Expect two to four days of headache and flatness during the taper. Alternatively, accept the steady state: the performance benefit and the habit-anchoring value persist even when the buzz does not.
