Question 1

What is GHK-Cu?

Accepted Answer

GHK-Cu is a copper-binding tripeptide naturally found in human blood plasma. It declines with age and has been studied for its role in tissue repair, collagen production, and gene expression. Lumivux delivers GHK-Cu directly via nasal mucosa, bypassing first-pass metabolism for superior systemic uptake.

Question 2

How do I use it?

Accepted Answer

One spray into each nostril once daily. Tilt your head slightly forward, insert the nozzle, and spray while breathing in gently through your nose. Use at the same time each day. Give it at least 4 weeks before evaluating results — cellular changes take time.

Question 3

How long before I notice something?

Accepted Answer

Most people report improved mental clarity and steadier energy within 2–4 weeks. Structural changes — HRV, recovery speed, body composition — tend to show up at the 8–12 week mark for people who track consistently.

Question 4

Can I use it with other supplements?

Accepted Answer

Generally yes. Avoid combining with other copper-containing supplements unless supervised by a physician — Lumivux delivers GHK-Cu directly and copper balance matters. If you take prescription medications, especially nasal medications, check with your doctor before starting.

Question 5

Is it safe?

Accepted Answer

Lumivux is made in a GMP-certified, FDA-registered US facility and independently tested for purity and potency. The nasal delivery system uses pharmaceutical-grade hyaluronic acid as a mucosal carrier. That said, supplements aren't for everyone — if you have a health condition or take medication, talk to your doctor first.

Question 6

Who shouldn't use it?

Accepted Answer

Not for use by pregnant or nursing women, people under 18, or anyone with a known allergy to any listed ingredient. Not recommended for people with active nasal infections, severe nasal polyps, or recent nasal surgery. Consult your physician if you have any underlying medical condition.

Question 7

Is this FDA approved?

Accepted Answer

Dietary supplements are not FDA approved — that's true across the industry. Our facility is FDA-registered and GMP-certified, and every batch is third-party tested before sale. These statements have not been evaluated by the Food and Drug Administration.

Question 8

Can this treat or cure a disease?

Accepted Answer

No. Lumivux is a dietary supplement, not a drug. It is not intended to diagnose, treat, cure, or prevent any disease. If you have a medical condition, work with your healthcare provider.

Question 9

How long does shipping take?

Accepted Answer

US standard: 3–7 business days. Expedited options at checkout. International: 7–21 business days depending on destination.

Question 10

Can I track my order?

Accepted Answer

Yes. A tracking number is emailed once your order ships, typically within 1–2 business days of placing your order.
