PER4M Advanced Magnesium is a high-absorption formula designed to support muscle function, recovery and nervous system balance. Each daily serving delivers 300mg of elemental magnesium from magnesium bisglycinate — a premium, bioavailable form that’s easy on digestion and built for results you can feel. Whether you're training hard, managing stress or looking to improve sleep, this is a smarter way to hit your daily magnesium needs.

Magnesium plays a key role in muscle contraction, electrolyte balance and energy metabolism, making it essential for performance and recovery. The bisglycinate form is bound to the amino acid glycine, helping it absorb more efficiently and reducing the risk of stomach discomfort. It’s also known for its calming effect, supporting relaxation and quality sleep — ideal for active people who need to switch off and recharge.

Per4m Nutrition

If you’re pushing your body daily or feeling the effects of fatigue, PER4M Advanced Magnesium delivers clean, effective support to help you perform, recover and reset.

INGREDIENTS: Magnesium Bisglycinate, Magnesium Stearate, Hydroxypropyl Methylcellulose Capsule.

No common allergen added.

4. Delivery Confirmation, Risk & Transfer of Responsibility

(a) Signature Required

A signature will be obtained at the point of delivery.
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.

5. Non-Delivery Claims

All non-delivery reports are investigated directly with the courier.
Where the courier provides proof of delivery (signature, photo or GPS record) matching the supplied address, the order is considered fulfilled and is not eligible for replacement or refund under this policy.
Where the courier confirms no delivery, we will either resend or refund the order promptly.

6. Failed Delivery, Refusals & Returns to Sender

If a parcel is returned due to customer error (e.g., incorrect address, failure to collect, or refusal of delivery), we may either:
- 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.

7. Same-Day Dispatch Guarantee (Express Orders)

Guaranteed for orders placed before 1 p.m. (Monday–Saturday).
Couriers may experience exceptional delays beyond our control; such events do not invalidate the guarantee for dispatch timing.

Customers alleging non-receipt after confirmed delivery may be asked to provide a police crime reference number. We reserve the right to cooperate with carriers and authorities in any fraud investigation.
