First, I shake it. I always take 7,5 ml (1,5 teaspoon) during breakfast and 7,5 ml before dinner. I drink it pure or dilute in water. I do it for 16 days with the conviction of resisting the temptation of failing. I rely on me.
After opening, I keep it in the fridge, away from heat and light, for no more than 30 days.
