420 Flex Berry Blaze Lemonade — THC Pre-Workout Sachet
5mg Delta-9 THC
150mg Natural Caffeine
300mg L-Theanine

Normal pre-workouts are built for stimulation.
Not performance.

Your best sessions happen when the noise drops and focus sharpens — not when anxiety peaks.

The brain is part of the workout.

Focus and mind-muscle connection are performance variables — not soft goals.

Cannabis and performance aren't opposites.

The right dose, in the right formula, creates a calmer, more locked-in training state.

Overstimulation isn't intensity.

Stimulant overload feels like effort while quietly eroding focus and recovery.

The Mechanism

Your body already has a system built for this

Exercise releases anandamide — the molecule behind runner's high. THC works with the same endocannabinoid system, so a precise 5mg dose supports the calm, locked-in state your body is already trying to create.

This Is For You If…

Built for athletes who train with intention.

  • You realized anxiety was the enemy — not effort.
  • You've mixed caffeine and THC on your own. You want precision, not guesswork.
  • You want to look forward to training, not just survive it.

"It cuts the veneer of anxiety and overthinking. I ran two miles 20 minutes after trying it — I hadn't run in 6 years."

"Actually feel the movement."

Proper amount of caffeine and an enhanced recovery period following any lift. Night and day difference when it comes down to simply moving weight around vs actually FEELING each movement. 5 out of 5!
