Analysis

It features a clinical 337.5 mg dose of KSM-66 ashwagandha and 5 mg of boron, both of which are used to support male hormonal health and stress response. I like that it provides 100 mcg of chromium picolinate to help your body manage sugars and cravings during fat-loss phases.

With 75 mg of caffeine from green coffee, it provides a gentle energy lift that is less intense than many other 'burners.' This is a solid choice for someone wanting to support their fitness goals while also protecting their daily vitality.

Pros

  • Uses branded KSM-66 ashwagandha for reliable support
  • Includes 5 mg of boron for hormonal wellness
  • Provides MCT and flaxseed oils for healthy fats
  • Moderate caffeine dose (75 mg) for a gentle lift

Cons

  • Zinc dose is relatively low (7.5 mg)
  • Stinging nettle and cordyceps are in very small, trace amounts
  • Bottle only contains a 30-day supply

Warnings

  • Take with food to prevent potential stomach upset from the thermogenics
  • Be mindful of the caffeine content if you are sensitive to stimulants
  • Avoid taking late in the day to ensure it doesn't impact sleep
