Gamertell has posted a mixed review of the Harcos' Mana Energy Potion energy drinks.
From the review:
"The Health Energy Potion seems to focus on both energy and the extra folic acid, biotin, ginseng and elderberry added in, while the Mana Energy Potion focuses on the energy and the dietary enzyme blend included in the drink. Both provided a substantial energy boost when needed, so I'd have to say a purchase would be dependent on what flavor a person prefers. I personally preferred the Health Energy Potion's apple cinnamon flavor to the Mana Energy Potion's undefined, possibly citrus blend. Plus the Health Energy Potion looked much more appetizing."
