USN B4-Bomb is their latest concentrated pre-workout for extreme energy and mental focus.

Get More Energy

The one thing athletes look for to increase their training performance is energy.

This product contains a blend of three stimulants which will ensure you bring your ‘A’ game to the gym.

Each serving contains 250 mg of Caffeine which completes the explosive energy blend.

Improved Mental Focus

TeaCrine is a biochemical equivalent of a molecule found in tea leaves and fruit.

It improves your mood, supplies longer lasting energy and is less likely to interfere with your sleep should you take the product before you evening workout.

Be Stronger

Lifting heaver weights will help stimulate more lean muscle.

Strength during your workouts is provided for by the addition of Creatine HCI, a concentrated form of Creatine which reaches your muscle cells at full potency.

Perform Till The End

Beta-Alanine gives you the stamina to perform at your best during your entire training session.

Improved Muscle Pump

Agmapure is a registered ingredient which promotes nitric oxide production.

An increase in NO may cause blood vessels to ‘expand’ allowing more nutrients and oxygen-rich blood to circulate around your body.

Uniquely Formulated

The energy blend is a winner for us. TeaCrine is non-habituating meaning that you’ll get the same effect with each serving. This pre-workout should give you the same reliable result with each workout.

Decent enough
Review by  
The product mixes reasonably well but the taste is extremely strong and not very plesent.
Takes a while to kick in but gives a steady energy output with no jitters or crash afterwards.
For the price i think its a tad expensive for what you get and others are preferred.
"secret weapon"
Review by  
Product works as advertised. I used it on my daily cycling routes. Also used it on my hill repeats sessions. Found it aids my focus and mental threshold.
I recover quicker on bike and can push a higher cadence before the burn arrives. Assists aggression at sprinting intervals. Great product when used responsibly. Dosage as prescribed is more than ample even for an endurance sport like cycling.
Review by

More Info

Do not exceed the recommended daily intake.


As with all supplementation, please consult your physician first (especially if you have a medical condition). Do not use if you are pregnant / lactating, under the age of 18 or sensitive to caffeine. Remember that an adequate state of hydration must be maintained when using this product. Have at least 8 – 12 large glasses of water per day. Do not exceed the recommended daily intake. Taking more than the recommended dose will not improve results and may cause adverse reactions. Large amounts of beta-alanine may cause paresthesia (pins and needles). Research suggest that this sensation is caused by beta-alanine binding to nerve receptors and it is thought to generally resolve on its own after about 1.5 hours. The sensation may subside after a few weeks of continuous use. If not, discontinue use of this product. For best results an appropriate muscle building eating and training programme should be followed.

Did everything as advertised. When I pushed myself and hit the wall, I was able to keep going. Kept me mentally in the mix for the entire workout. Felt stronger. Will remain a part of my regular routine.

Review by  
no complaints from me. maybe that the price is a bit steep for a local product, but other than that i had great energy for my whole workout, no crash and felt great.
Review by  
Used a lot of pre workouts over the years and this had me excited with all the marketing and advertising, what usn does best, fool consumers. Had a slight increase in energy and then a sudden drop. Bad quality as usual from them.
