ENGINEERED MUSCLE PQQ – Pyrroloquinoline Quinone

PQQ (Pyrroloquinoline Quinone) is a redox-active compound primarily used for mitochondrial support and cellular energy optimization. It plays a role in stimulating mitochondrial biogenesis through pathways such as PGC-1α, while also protecting existing mitochondria from oxidative stress.

The practical outcome: improved cellular energy efficiency and better resilience under metabolic stress.

The challenge with NMN capsules goes beyond bioavailability; its stability with heat and acidic environments also risks quality and effectiveness, as storage conditions can cause degradation. NMN has been known to degrade into niacin, but with NNB’s beadlet technology, stability is ensured before taking the supplement

Mitochondrial Biogenesis & Energy Output

PQQ supports the creation of new mitochondria and enhances the function of existing ones. This makes it highly relevant for:

Cognitive performance
Physical performance
Recovery
Longevity-focused protocols

Unlike stimulants, its effect is cellular — not neurological stimulation, but actual improvements in energy production capacity.

Antioxidant & Cellular Protection

PQQ is a potent redox cycling compound, meaning it can repeatedly neutralize oxidative stress without being rapidly depleted. It has been shown to reduce lipid peroxidation and support mitochondrial membrane integrity.

This is particularly relevant when oxidative stress is elevated (intense training, aging, metabolic strain).

Cognitive & Neurological Support

PQQ may support nerve growth factor (NGF) signaling and has shown improvements in memory, attention, and mental fatigue in human trials. Its cognitive benefit is largely tied to improved mitochondrial function in neurons.

Synergy Within the Engineered Line

Engineered PQQ × Engineered Urolithin A

Urolithin A supports mitophagy (removal of damaged mitochondria).
PQQ supports mitochondrial biogenesis (creation of new mitochondria).

Together:

Clear out dysfunctional mitochondria
Stimulate production of new, efficient ones

This creates a full mitochondrial turnover strategy.

Engineered PQQ × NMN BIONmn

NMN increases NAD+ levels, which are critical for mitochondrial energy production and sirtuin activation.

Stacking effect:

NMN increases NAD+ availability
PQQ increases mitochondrial quantity and protects them
Result: improved mitochondrial density + improved energy output capacity

This pairing makes sense in performance, cognitive, and longevity-focused protocols.

Dosing Range

Effective range:
10–20 mg daily

3. Delivery Options – Republic of Ireland, EU & International

Available services, prices and estimated transit times are displayed at checkout.
Delivery times vary by destination and customs clearance processes.
Recipients are responsible for any local import duties, taxes, or customs charges.
We cannot influence or expedite customs procedures in destination countries.

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.

8. Working Days Definition

“Working Days” means Monday to Saturday, excluding UK Bank Holidays. Orders placed after 1 p.m. on a Saturday or on a Bank Holiday are processed on the next working day.

9. Evidence & Investigation

We maintain courier records, including time-stamped tracking data, GPS coordinates and photographic delivery evidence, for audit and anti-fraud purposes. 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.
