This is a one-time payment. You’ll be charged today for your order, and that’s it!  In fact, we don’t offer monthly subscriptions at this time. You can only make a one-time purchase. We consciously chose not to offer subscriptions while there is uncertainty in the global supply chain. If we face shortages of any one of our premium ingredients, we simply have to stop selling until we can restore supply.  Again, that’s why we recommend you order 3+ bottles today. There’s no risk because you’re covered by our guarantee.
