Strom StimuMAX EXTREME
Note on Texture:
This product contains high levels of hygroscopic ingredients (ingredients that naturally absorb moisture from the air). As a result, the powder may clump or harden over time.
This is a normal characteristic and does not affect the quality, potency, or effectiveness of the product. Any clumps can be easily broken apart with a fork or spoon before use.
Prepare for the EXTREME pre workout experience! Rick decided it was time for a step up from the well renowned StimuMAX Black Edition. This new blend takes your workouts to new heights with an infusion of the potent bitter orange extract. Based on the feedback from our athletes this will take your workouts to the next level and become a staple for your heavy sessions.
Don't settle for ordinary. Go Extreme.

General Delivery Terms
No Signature Required
By selecting “No Signature Required”, you authorise our courier to deliver your parcel to your address or a nominated safe location without obtaining a signature. Our delivery partners capture photographic and GPS confirmation of the delivery location. Once this confirmation is recorded, the order is deemed successfully delivered and the risk of loss or theft passes to you. NI Supplements will not be responsible for any loss, theft, or damage occurring after delivery has been confirmed by the courier.
Signature Required
A signature will be obtained at delivery. Until a signed handover occurs, the parcel remains at the sender’s risk. This option offers full proof of receipt and is recommended if you cannot ensure someone will be present to receive the parcel.
Same-Day Dispatch (Express)
Guaranteed for orders placed before 1 p.m. Courier network delays can occasionally occur.
Working Days & Cut-off
Processing Monday–Saturday (excluding Bank Holidays). Orders placed after 1 p.m. are processed the next working day.
Risk & Responsibility
Once an order has been confirmed delivered by our courier (via signature, or via photo & GPS confirmation where “No Signature Required” was selected), ownership and risk of loss or damage pass to the customer. NI Supplements’ delivery obligation ends at this point.
Failed Delivery & Returns to Sender
If an order is returned due to customer error (for example: providing an incorrect address, failure to take delivery, or failure to arrange collection/redelivery), a re-shipping fee applies. Alternatively, we can refund the item price minus our outbound shipping costs. If the error is ours, we will re-ship at our expense.
Non-Delivery Claims
All non-delivery claims are investigated with the courier. Where the courier confirms delivery (via signature or photo/GPS evidence), orders are not eligible for replacement or refund under this policy.
