Someone told me milk. I don't understand how milk would potentiate methamphetamine or stimulants, but honestly I've always been one who felt that with the exception of synergistic combinations, which isn't the same thing, potentiators usually just enhance unwanted side effects especially with stims. Better to just take more, or switch to a more powerful ROA. Either way, you'll never find yourself satisfied for a period of time longer than a few days, without just increasing your stim dose or your potentiators.
