What Herolean feels like

  • Raw, all-in energy from warm-up to burnout
  • Tunnel-vision focus
  • Serious heat and sweat
  • Drive that holds on low-calorie days

Train when others quit.

Herolean isn't for everyone. It's forged in the underground — built for night grinders, iron addicts and no-compromise lifters who train when others quit.

2.5 g L-Carnitine L-Tartrate. A heavy stimulant core: 500 mg Eria Jarensis, 500 mg Beta PEA and 425 mg total caffeine with extended-release zümXR® so it doesn't fade mid-session. Synephrine and ProGBB® crank the heat, and magnesium, sodium and potassium are on board for the sweat.

More than a thermo powder — a declaration of drive.

Used it for my morning cardio, great energy, and for sure felt the thermogenic nature, had good appetite suppression. Taste was ok. But overall loved it.

Herolean FAQ

Still deciding? Email info@darklabsofficial.com and a real person will answer.

How should I take it?
Start with half a serving to assess your tolerance. Mix one full serving (serving size is listed on the label) with 8–12 oz of cold water and drink it 20–30 minutes before training. Do not exceed one full serving in 24 hours, skip other caffeine sources that day, and avoid taking it within 6 hours of sleep.
What is Herolean?
An extreme-stim thermogenic powder: 2.5 g L-Carnitine L-Tartrate, a heavy stimulant core (425 mg total caffeine incl. extended-release zümXR®, plus 500 mg Eria Jarensis and 500 mg Beta PEA), Synephrine and ProGBB® for heat and sweat, and electrolytes on board. Take it before training on cutting days.
Can I take Herolean with a pre-workout?
No. Herolean is already fully loaded with stimulants — don't combine it with a stimulant pre-workout or other caffeine the same day. A stim-free pump product or creatine is fine.
