You've got questions, and we've got answers. If you're the 1 in 10 who doesn't just email us for an answer, then today is your lucky day.

Q. How quickly will my order arrive?

Our shipping is SUPER fast! Most orders are shipped within 24-hours. Not only that, all orders are shipped express via AusPost for the price of regular shipping. As such, most customers can expect to receive their order within 48 hours. Please note that if you placed a backorder, your order will be shipped once we're back in stock (an estimate will be sent to you).

Q. What’s our refund policy?

It’s awesome! Okay, jokes aside we believe that people should only pay for stuff they get value out of, and we're so confident that you will like our products that we have a "no questions asked" money back guarantee policy! Instead of selling mediocre products and not offering refunds when customers are inevitably let down, we instead focus on formulating products that actually work and provide ongoing value. How crazy are we!? But if you were let down and would like a refund, simply shoot a message to help@gethapi.me for your money back.

Q. I want to know more about the research.

Each of our products use natural earth grown ingredients which follow strict clinical profiles, in regards to safety and efficacy. You can learn more about our research and development process, as well as our quality assurance protocols on our science page here.

Q. How are our products formulated?

Our products are formulated by our in-house team of neuropharmacologists and nutritionists. Our lead researchers are Adam and Jack. Adam is a nutritionist and data-scientist from Monash University in Australia. Jack holds a PhD in Neuroscience from the University of Melbourne, and a BSc in Neuropharmacology from King’s College in London. You can learn more about the process they used to formulate our products here.

Q. I want to know more about your products safety.

Each of the ingredients in our products have clinically-proven, long-term human safety and toxicity profiles to ensure there are no side effects. Second to that each ingredient falls under the “GRAS” framework, which means Generally Recognised as Safe. All clinical safety data has been studied on human models, not just animal models. Finally, all of the ingredients we use are natural. We don’t use any man-made ingredients invented in a laboratory.

Q. Are our products vegan?

All of our products are vegan, gluten-free, heavy metal and pesticide free! How cool is that.

Q. Where do we ship to?

Currently we just ship to Australian customers! In the future we plan to utilise distributed warehousing to stock our product in many locations around the world, to offer fast and affordable shipping.

Q. What is the shelf life of our products?

Our Flow product will be good to consume for a good two years after purchase! Check the expiry date on your bottle for the exact details.

Q. Can our products be taken with coffee?

Yes! In general we recommend consuming less coffee when you take our Flow product, because it already includes ingredients which boost energy and reduce mental fatigue. In addition, one of the main ingredients (TeaCrine) actually potentiates the effects of coffee, meaning that if you have Flow + coffee you will get quite a kick. Experiment with different amounts and see what works best for you.

Q. How can I learn more about your Ts&Cs?

You can read our terms and conditions here. Unlike most companies, we provide a ‘plain english’ explanation under each paragraph of legal info, so that everyone who buys our products are 100% aware of our terms.

Q. Does Flow interact with any medications?

One of the ingredients in Flow inhibits cytochrome P450 which is important for drug metabolism.  Persons taking immunosuppressants (e.g. Sandimmune), calcium channel blockers (Norvasc), anti-arrhythmics/hypertensives (Coreg, Avapro, Cozaar), sedatives (Xanax, Ambien, Clozaril, Phenobarbital) or any other medications known to be metabolized by P450 enzymes should consult with a doctor before using this product.

For Doctors: This product exhibits non-competitive inhibition of CYP2C19, CYP2C9, CYP1A2; competitive inhibition of CYP3A4; and weak inhibition of CYP2D6
