The pre-workout category is still a mess.
Underdosed formulas. Outdated thinking. Products that look the part but don’t deliver. Then the other extreme - overhyped, questionable formulas that rely on stims instead of substance. Somewhere in between, there are brands doing it right.
We are that brand.

- Until a signed handover occurs, the parcel remains at NI Supplements’ risk.
- Once signed for by you or a nominated recipient, delivery is complete and responsibility transfers to you.
(b) No Signature Required / Authority to Leave
By selecting “No Signature Required” or authorising an unattended delivery / safe place, you:
- Expressly instruct the courier to deliver the parcel to your address or nominated safe place without obtaining a signature.
- Acknowledge that the courier’s photo and GPS confirmation constitute full proof of delivery.
- Accept that once such confirmation is recorded, the order is deemed successfully delivered, and
- Agree that risk of loss, theft or damage passes to you immediately upon that confirmation.
Accordingly, NI Supplements’ delivery obligation is fully discharged once the courier records a delivered scan with accompanying GPS/photo evidence.
If you are concerned about parcel security at your address, please select “Signature Required” at checkout. This is recommended for high-value orders or where the delivery location is unattended or visible from a public street.

- Resend it after payment of a re-shipping fee; or
- Refund the product value less the original outbound shipping cost.
- Where the error or delay was caused by NI Supplements or our courier, we will resend at our expense.
