3x Small Bottles KetoneAid KE4 Ketone Ester (up to 18 days worth)
This is 3 small bottles like you may have seen on Instagram.
Each bottle is technically one serving, but ignore that (unless you are a pro athlete). The bottle has 60ml (30g of ester). Many are taking as little as 10ml on a daily basis (about $5 worth). It comes with a measuring tube, that you can dilute the ester by filling the rest up with cold water.
