When will Bulletproof Whey and Collagen be back in stock?

Collagen is back in stock. We continue to work on a steady supply of whey.

What's so good about Bulletproof Coffee Beans?

In order to always provide the freshest coffee beans, Bulletproof sources beans from an estate in Columbia for roasting in December to June and sources coffee beans from an estate in Guatemala to provide beans from June to December.

A meticulous processing method from picking the cherries to bagging the coffee which makes the coffee as free of mycotoxin (mold) as possible. This is a single origin (from one farm and no mixed batches), grown at high altitude, mechanically processed, passive organic and Rainforest Alliance certified coffee (farmers earn 30% more than their counterparts under FairTrade programs).

You can now drink coffee without experiencing a "high" and then crashing after a couple of hours, repeating the cycle for the rest of the work day. You can avoid the nausea, jitteriness and headaches associated with many other brands of coffee – even other premium single origin beans that can vary in quality week-to-week. You get the antioxidant benefits of coffee without negating them with mycotoxins common to 95% of coffee.

For a full list of benefits, see the manufacturer's website: www.bulletproofexec.com/coffee Combine the coffee with MCT or Brain Octane Oil and some deliciously creamy butter or ghee from grass-fed cows for an amazing Bulletproof Coffee experience that will leave you satiated, focused, energised and happy all day. :-)


How Do I Make Bulletproof Coffee?

Here's a Recipe:


  • At least 2 tbsp unsalted grass-fed butter or ghee (I like up to 6 tbsp, or 80g or 88 ml).
  • 1-2 tbsp of Brain Octane or MCT oil (15-30 ml).
  • 2 cups (~453g or 500ml) of hot coffee brewed with low-toxin beans (like Bulletproof Upgraded Coffee). You'll need 12-15g of beans which works out to about 2-3 tablespoons.
  • Also check out our neat How to Make Bulletproof Coffee video :-)


  1. Brew 2 cups of black coffee with Upgraded Coffee beans. A steep time of 60s is enough. The longer you steep, the more bitter your coffee (and potentially less flavourful).
  2. Preheat a blender with some hot water. Then remove the water and add butter and MCT oil.
  3. Pour your coffee into the blender.
  4. Blend and enjoy! (Or shake up in a Klean Kanteen)
  5. Optionally, add in raw chocolate powder, cinnamon and/or vanilla.


Do you deliver to New Zealand?

Yes! View shipping rates to New Zealand. We deliver using a trackable courier service. Please allow 4-6 business days for delivery. Note that if your order is over the allowable duty-free threshold of NZ$300 in value you will attract the attention of New Zealand customs and will have to pay applicable duties and GST. As soon as we have a large enough volume of orders from our New Zealand customers, we will set up a warehouse in Auckland so we can service you faster and at better shipping rates. :-)


Where's my order?

All Australian OptimOZ orders are sent via trackable E-Parcel with Australia Post or Star Track Express.

If you have received a dispatch notification email, you can use the tracking number included in it to find out where your order currently is by entering it at Auspost.com.au/track. You can also find your tracking number by logging into your account.

If you chose Star Track Express, you can track your order at Startrack.com.au.

If you have not received a dispatch notification within two business days of placing your order, please contact us and we will do whatever we can to help! Note that notifications are sent between 5pm-6pm.

New Zealand customers: To track your package, enter your order number at http://eretaillogistics.com.au/tracking.php.

On the rare occasion, we may run out of stock of a product which may delay your order. We will do our best to make sure this does not happen, but if it does we will keep you well informed about what's going on and give you complete flexibility to change or cancel your order.


When will my order be delivered?

Australia Post's regular parcel delivery timeframes are listed here.

Express Post deliveries can arrive as early as the next business day within metro centers.

If you live within Sydney metro, then you are unlikely to benefit from Express shipping as it will probably take just as long as regular post.

If you have received a dispatch notification from us, you can track your order here.

If you have not yet received a dispatch notification, note that if an order is received by 12pm then we dispatch the same day. Otherwise, your order will be packed and shipped on the next business day and you will typically received a dispatch notification between 5pm-6pm (AEST.)

For more information about how your order is processed and delivered, see our Shipping Information page.


What coffee gear is best for making Bulletproof Coffee?

Check out our recommended Bulletproof Coffee Making Kit or our recommended Aeropress Coffee & Espresso Maker, Porlex Mini Grinder and the Able Stainless Steel Filter in our Coffee Gear section.


Can I buy Bulletproof products in a shop?

Look for a Paleo Cafe near you in Australia. They currently stock our MCT oil and coffee, with more products being added.


Which Heartmath Heart Rate Variability training device is best for me? Inner Balance, emWave2 or emWave Pro?

If you have an iPhone, we recommend the iPhone sensor rather than the emWave2. The emWave pro is good to use while working at a computer but is inconvenient and not portable compared the the iPhone sensor. As for the technology I believe it is effective and of a high quality. The Inner Balance app (a free download from the iTunes store) is great and has all the information and recording options that 99% of users would need. The other 1% at the extreme end of the biohacking spectrum would enjoy the games and more data that you get from the emwave pro and the emwave2 as well, but to a lesser extent.


I got my Heartmath HRV trainer, now what?

So you're ready to start coherence training - great! Watch these user-friendly training videos and read this handy reference guide: Heart Rate Variability Analysis - How to Improve your Training Performance


Can you help me get started with my emWave or Inner Balance Trainer?

The manufacturer has a handy dandy support website that is in the best position to help you. You can also contact their technical support team for help: http://www.heartmath.com/support/


I have a newer iPhone or iPad, how can I use the Inner Balance Trainer?

If you have the 30-pin (older) version of the Inner Balance Trainer, you can still use it with the newer iOS devices but you will need to get a lightning adaptor: http://store.apple.com/au/product/MD823ZM/A/lightning-to-30-pin-adapter
The lightning adaptor version of the Inner Balance Trainer is now available. This is designed for all iOS devices including these versions (and newer): iPhone 5, iPad 4, iPad Mini & iPod Touch 5.


My Inner Balance Trainer isn't working. What do I do?

Is Bulletproof Glutathione supposed to taste gross?

Yes, it's nasty :) That's why it's recommended you squirt it under your tongue in an attempt to avoid violating your taste buds. Try storing and consuming after refrigeration – this definitely helps.


I love Bulletproof  Coffee and want to sell it in my shop. Do you do wholesale?

Awesome! Yes, we can supply you. Send us an email to get the ball rolling.

Why won't my coupon code work?

Five possible reasons:

  1. It may be expired.
  2. You may have typed a number instead of a letter.
  3. You have not met the minimum order amount to validate the coupon.
  4. The coupon is restricted to a particular product or collection of products.
  5. Generally, coupons are not applicable to 2.25kg bags of Upgraded Coffee, electronics, kits, protein powders or cow shares.


How can I join a cow share?

Visit the cow share product page and choose your location. Delivery available in NSW and ACT.


Where can I Buy Bulletproof Coffee, Upgraded MCT Oil and the other products?

Currently, OptimOZ.com.au is the best place to buy Upgraded Coffee, MCT Oil and the rest of the product range, together with select superfoods and nootropics. Paleo Cafes stock MCT Oil and Upgraded Coffee, with more of the like being added to their shelves each week. Find a Paleo Cafe near you.


Where can I find Grass Fed Butter in Australia?

Woolworths HomeBrand and Westgold are the most economical options. Some tastier options include Organic Times (actually states 'grass-fed' on the label), Ashgrove and Paris Creeks. For the adventurous, try Pepe Saya's grass-fed cultured butter or ghee. More information is in this blog post.


Do you have a phone number?

We have a very small team and currently don't have the capacity to take phone calls. If we did display a phone number, i'm afraid no one would answer when you called and you would be stuck with voicemail. f you want to enquire about the status of your order, please email info@optimoz.com.au. Generally, sending us an email is the fastest way to get a response on any query you have. Otherwise we have a very helpful faq


The bag of coffee I received is inflated – I don't usually buy bags of coffee like this that are distended. Is this a problem?

This is ok. Upgraded Coffee is not vacuum sealed but rather put into multi-layer foil bags that contain a one-way valve. The valve allows the freshly roasted coffee to degas while minimizing oxidization degradation. We bag our coffee directly after it is roasted to maximize it's freshness. This is not a standard practice for commercially available coffee and will cause inflation on occasion, but this does not affect the quality of the coffee negatively whatsoever.


What is your Returns Policy?

Our goal is to keep you happy. We generally will accept returns of unused products within 30 days of purchase. The returns process varies depending on the product/brand in question.

  • For food items, the product must be unused, in its original packaging and undamaged so it can be resold. You may return it for a refund or credit within 30 days of the date of dispatch.
  • For electronics, the first point of contact is the manufacturer. For Heartmath products, please contact support@heartmath.com  
  • Shipping charges are non-refundable unless the return is a result of our error, in which case we will provide you with a Reply Paid address for the return leg. Before returning an item, please obtain a return authorisation by emailing us.
  • If you receive a product that is faulty in anyway, we will of course make this right.
