Frequently Asked Questions

What is fresh activation?

You receive dry powder and base separately, then combine them at home weekly. This keeps peptides at full strength instead of sitting pre-diluted for weeks.

How do I use GHK-Cu and AHK-Cu?

GHK-Cu Skin Serum: Apply 1ml twice daily (morning and evening) to clean skin. AHK-Cu Scalp Treatment: Apply 2ml once daily in the evening directly to the scalp. Activate fresh each week by pouring powder into base. Use the activated mixture within 7 days for best results.

What's included in each monthly kit?

A 4-week supply: 4 powder vials and 4 Nano Delivery Matrix bottles. Activate weekly, use within 7 days.

When will my pre-order ship?

Pre-orders will ship in late August 2026. Shipping is via USPS Priority Mail to domestic USA addresses only. Delivery typically takes 3-5 business days after shipment. We are not responsible for carrier delays or external factors beyond our control.

What's your return policy?

Unopened products can be returned within 30 days of receipt for a full refund. Once opened or activated, products are non-returnable and non-refundable. Peptides degrade upon exposure to air and cannot be resold. See our Terms of Service for complete details.

How should I store my products?

Keep powder vials and Nano Delivery Matrix bottles in a cool, dark place, away from heat and sunlight. Both are packaged in amber glass for light protection. Once activated, use within 7 days.

What if I experience skin irritation?

Always patch test before use. If irritation occurs, discontinue immediately and rinse thoroughly with water. For persistent irritation, consult a dermatologist. We are not responsible for allergic reactions or individual sensitivities. See our Terms of Service for full liability information. Individual results vary.

Can I use these with other skincare?

Yes, AURIX 28 products can be used with other skincare. However, avoid vitamin C (ascorbic acid), EDTA-containing products, and chemical exfoliants on the same morning as GHK-Cu, as these can interfere with copper peptide stability. Space them out or use on different days for optimal results.

What is the Nano Delivery Matrix?

A nanoliposomal delivery system formulated for enhanced absorption into the skin. Zero EDTA.

What are the exact product specifications?

GHK-Cu Skin Serum: 450mg per weekly activation, 3% concentration, $175/month (4-week supply). AHK-Cu Scalp Treatment: 375mg per weekly activation, 2.5% concentration, $180/month (4-week supply). Both use Nano Delivery Matrix technology.
