Killer Labz
When It’s Time to Train Like a Machine
There’s no warm-up. No easy set. Stim Reaper is built for those who walk into the gym ready to destroy every session — not survive it.
With a name like Stim Reaper, you already know what to expect: a wave of energy, dialled-in focus, and unrelenting drive that keeps you locked in from start to finish.
This is the one you take when average pre-workouts just don’t cut it anymore.
What Makes It Hit Differently
Killer Labz combined a triple-impact formula: performance, energy, and nootropic focus.
Each scoop delivers smooth, sustained intensity — without chaos or crash.
You get clean endurance from Beta-Alanine and Taurine, precision stimulation from the Energy Matrix, and mental lock-in from the Nootropi-Stim blend.
Whether it’s a heavy leg day or late-night upper-body grind, Stim Reaper doesn’t just wake you up — it switches you on.

CTL Observation
We tested Stim Reaper across multiple sessions — it hits fast, stays steady, and leaves no crash in its wake.
Focus remains sharp through high-intensity training, and the American Pop flavour is surprisingly smooth for such a loaded formula.
A perfect pick for hardcore lifters, shift workers, or anyone needing full mental engagement from the first rep to the last.
