What you get
This post is a bit different. I can’t tell you if this works, because the box literally landed today and I haven’t taken anything. What I can do is show the receipt and read the box out loud. Ordered July 19 through the Barneys New York Beauty online mall in Korea. Checkout math: product ₩82,000, shipping ₩3,000, discount −₩62,200. Actual amount paid: ₩22,800. 6g {29. 8g (25ml liquid + 800mg tablet × 2) × 7 bottles}’ — so one box is 7 days, two boxes is 14. A daily dose is one liquid vial plus two tablets, which I assume is where the ‘Double Action’ name comes from. Ingredients printed on the box: indigestible maltodextrin, Coleus forskohlii extract, green tea extract, vitamin B1, vitamin B6, pantothenic acid. The front prints three function labels: body fat · bowel function · energy. That’s the box talking, not me. One thing worth knowing about Korea: products like this carry an official ‘health functional food’ mark, and on the same panel the box is required to print — and mine does — ‘this product is not a medicine intended for the prevention or treatment of disease. ‘ Straight off the packaging. If I actually finish the 14 days, follow-up post. For now: ₩22,800, two boxes, zero opinions.
