We accept all major credit and debit cards, PayPal, Apple Pay, Google Pay, and Shop Pay. We also accept bank transfer (EFT) within Australia — note that bank transfer orders require one additional business day to process before despatch.

We also accept Bitcoin for those who prefer it. At checkout, select the cryptocurrency payment option and follow the prompts.

We despatch orders quickly — often the same day. If you need to make a change, email us at info@optimoz.com.au or message us on WhatsApp as soon as possible. If your order hasn't been packed yet, we'll do our best to accommodate changes.

If your order has already been despatched, we won't be able to redirect or modify it, but you can return items under our 90-day satisfaction guarantee.

Yes. We supply wholesale quantities of selected brands including Bulletproof®, BiOptimizers, Kimera Koffee, and Primal Collective™. To enquire, email us at wholesale@optimoz.com.au with your business details and the products you're interested in.

Check your spam or junk folder first — our emails occasionally land there. If you still can't find it, there may have been a typo in your email address at checkout. Contact us at info@optimoz.com.au with your name and approximate order date and we'll locate it for you.

We don't offer phone support — our small team operates remotely across different time zones, so calls aren't something we can reliably staff. Email and WhatsApp both work well and typically get faster, more accurate responses than a phone call would.

First, check your tracking at track.optimoz.com.au. Delays around public holidays and in regional areas are common with Australia Post.

If tracking shows your parcel as delivered but you haven't received it, check with neighbours or your building manager — Australia Post sometimes leaves parcels in unexpected locations. If you still can't locate it, email us at info@optimoz.com.au and we'll follow up with the carrier on your behalf.

We offer a 90-day satisfaction guarantee. If you don't see the results you expected from any supplement, contact us within 90 days of purchase and we'll issue a full refund — no questions asked, no restocking fee.

See our full returns policy for details on damaged items, exchanges, and exclusions.

Email info@optimoz.com.au with your order number and a brief description. We'll respond within one business day and, for approved returns, provide a Reply Paid return label — no cost to you for return shipping within Australia.

We're sorry to hear that. Send us a photo of the issue to info@optimoz.com.au and we'll despatch a replacement or process a full refund immediately — no need to return the item.

Once we receive your return, we'll inspect and process it within 7 business days. Your bank or payment provider then takes a further 2–4 business days to post the refund to your account.

If you haven't received your refund after 5 business days of your confirmation email, check your bank statement first — refunds can sometimes appear without a clear label. If it's still missing, contact us.

The Inner Balance Bluetooth works with both iOS and Android and is the most versatile option for everyday use — portable, app-driven, and ideal for on-the-go coherence training. The Inner Balance Lightning version is iPhone-only.

The emWave2 is a standalone device (no phone required) that suits desktop or home use, and offers more detailed biofeedback data for advanced users. It's less portable but provides richer analytics.

For most people, the Inner Balance Bluetooth is the best starting point. If you're unsure, email us — we're happy to help narrow it down based on how you intend to use it.

Brew 2 cups of Bulletproof Coffee, then blend it with 1–2 tbsp of Brain Octane or C8 MCT oil and 1–2 tbsp of grass-fed butter or ghee until frothy. The blending step is essential — it emulsifies the fats and creates the signature creamy texture.

A full step-by-step guide including tips on ratios and variations is available in our Bulletproof Coffee recipe post.

VitalityIQ™ is OptimOZ's own supplement brand, developed after 12 years of sourcing the world's best supplements. We built it to fill the precise gaps that no other brand in Australia currently covers — particularly in the areas of cellular defence, NRF2 pathway activation, and plant-derived longevity compounds.

The range launched with Sulforaphane (broccoli seed extract) and is expanding to include DIM, Fisetin, NAC, EGCG, and more. All VitalityIQ products are formulated to clinical dosing standards with no fillers.

Many of our supplements are designed to be taken together — for example, NMN pairs well with resveratrol and TMG, and magnesium complements most evening protocols. However, we're a supplement retailer, not a medical practice, and can't provide personalised health advice.

If you're taking prescription medication or managing a health condition, we recommend consulting your GP or a qualified naturopath before starting any new supplement regimen.
