I'm in Australia.. I don't usually say this, but I've found the best place to buy it is on Amazon. Just make sure it's the actual brand selling it and not some 3rd party unknown. I've bought 2 brands - https://www.amazon.com/Paraxanthine-Supplement-Concentration-Productivity-Nootropic/dp/B0CC68SS6T And https://www.amazon.com/Paraxanthine-Energy-Focus-Nootropic-Caffeine/dp/B0DHR55JXS/ref=pd_aw_subss_hxwPER_sspa_mw_detail_m_sccl_5_1/130-0820518-1311611 Both the same price, both are only available on the US site unfortunately. Personally I prefer the 2nd link because of the more premium feel to the brand. But both are the same price and the same thing. Both also have they're own websites where you can order from. Just for me Amazon is cheaper and faster with shipping. Hope this helps
