Game-changing results

Game-changing results

†Individual results may vary. Based on a customer survey of Cycle Defender users taking five capsules daily over a 12-week period. These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease.

Every serving of Cycle Defender is built on clinically studied ingredients at doses you can look up. No proprietary blends, no guessing what's actually in the capsule.

  • Said they felt more in control of their health while training hard†

  • Reported steadier day-to-day energy through a full block†

  • Said they'd never run another block without support†

  • Noticed better recovery between hard sessions†

Five capsules.
With a meal. Done.

  • Once a day, Done.

    Once a day, Done.

    Five capsules with your first meal and the protocol is finished for the day. No timing windows, no cycling off, no seven-bottle stack to keep straight.

  • Built for demanding blocks

    Built for demanding blocks

    The harder you train, the harder your liver, kidneys and heart work in the background. Cycle Defender covers all four systems at once, so support scales with the load.†

  • Made for the whole run

    Made for the whole run

    A bottle is 30 servings. Most blocks run 12 to 16 weeks. The guys whose panels come back boring planned for the full run from day one.†

Not all organ support
is created equal

Clinically dosed, printed in full

Most support formulas lean on one hero ingredient at a token dose, then bury the rest in a proprietary blend so you cannot check the math. Cycle Defender puts every active on the label with its milligram amount: 1,000 mg NAC, 500 mg milk thistle, 500 mg arjuna, 200 mg CoQ10.

AstraGin® is in the formula for one reason: absorption. A dose only counts if your body takes it up. Liver, kidneys, heart and metabolism, all four covered, all of it readable before you buy.†

The Cycle Defender actives: a closer look

  • MILK THISTLE — 500 mg

    Silymarin from milk thistle is among the most-studied botanicals for liver health, supporting normal liver function and your body's own detoxification pathways.†

  • N-ACETYL CYSTEINE — 1,000 mg

    A full gram. The direct precursor your body uses to build glutathione, its master antioxidant. Most blends stop at 400 to 600 mg.†

  • COENZYME Q10 — 200 mg

    Powers cellular energy production and supports cardiovascular function, keeping a heart under extra load supplied with what it needs.†

  • BERBERINE — 250 mg

    Supports healthy metabolism and blood-sugar balance, the system most organ-support formulas ignore completely.†

  • ASTRAGALUS

    A traditional adaptogen used to support kidney function, immune resilience and recovery through demanding training phases.†
