Do You Have Any Questions?
It helps you have better workouts: steady energy, clear focus, and support for strong sets, so you can train harder and finish feeling good.
Each scoop of Kathartik contains approximately 175mg of caffeine. If you are sensitive to caffeine, it's best to start with 1/2 scoop or less to evaluate tolerance. It is good practice to be aware of your total daily caffeine intake. Do not combine Kathartik with other caffeinated or "energy" products.
Kathartik is made for a smooth, in-control feel. If you’re sensitive, start with ½ scoop or less, drink water, and see how you feel before increasing.
Most energy drinks are just caffeine and sugar. Kathartik actually enhances your performance by increasing blood flow, focus, and strength so you can train harder and make real progress, not just feel awake. Kathartik costs significantly less per serving than single cans of energy drinks.
That tingling (“pins and needles”) is usually from beta-alanine. Kathartik doesn’t use beta-alanine, so you will not feel "tingles".
We show every active ingredient and its exact dose with no proprietary blends or hidden doses. Kathartik is produced in an NSF and GMP–certified facility under strict quality and safety standards. This batch was third-party tested for heavy metals (arsenic, cadmium, mercury, and lead), and none were detected. It also passed potency testing to confirm that every ingredient meets its advertised strength.
You’re covered by our 90-day money-back promise. If it’s not for you, we’ll make it right.
