What it is
DNA Sports H8 is a high-stimulant pre-workout designed for serious training days. It is the pre-workout you reach for when the session in front of you is heavy, long, or both, and you need to switch on fast.
Why people choose a high-stim pre
A high-stim pre-workout is not for everyone, and it is not a daily product. It is for the sessions where you need genuine drive: heavy compound work, long conditioning blocks, fight camps, big leg days, athlete training blocks. Used properly, a high-stim pre helps you get more out of a session without leaning on three espressos.
If you are stim-sensitive, new to pre-workouts, or training daily, look at a stim-free pre (DNA Sports Thank Pump For That) or a more moderate option instead.
Who it is for
A strong pick for:
- Experienced lifters and athletes used to high-stim pre-workouts
- People who train hard a few times a week and want a focused tool for those sessions
- Fight-sport athletes and powerlifters in heavy training blocks
- Customers who already use pre-workouts and want a harder-hitting option
Not for: stim-sensitive users, anyone training within 6 hours of bed, anyone with cardiovascular concerns, or anyone under 18.

What sets DNA Sports apart
DNA Sports is one of the brands we stock because the formulas are dosed for people who actually train. H8 is built with the stim levels and active ingredients to match the name, not a polite scoop of caffeine pretending to be a pre-workout.
Browse the full DNA Sports range.
How to use it
Start with half a scoop the first time you take it to assess tolerance. Take 20-30 minutes before training, mixed into 250-400ml of water. Do not take within six hours of bed. Do not exceed the maximum daily dose on the label. Do not stack with other high-caffeine sources on the same day.
Not suitable for under-18s, pregnant or breastfeeding women, or anyone with high blood pressure or heart conditions. Speak to your GP if you are on prescription medication before using a high-stim pre-workout.
