Although I took this medication back when I was around 12 years old (not sure how that turned out but I received complements I was tall for a girl) , I believe that it still worked. I am now 20 and I recently took this in hopes of my height grow a bit. I was 5'7" and I recently checked that I am now about 5'8" ish . The process didn't take right away, I just realized that I'm suddenly in different eye levels with things I used to do ( like standing in front of my mirror-- I use to be eye level with it, now I have to bend down a little) so the process takes a slow one. I took one set for a month [ after lunch for every other day since that's how I took it when I was younger] however, id like to point out that this might not be for everyone since bodies are different from the rest. I gave it 4 stars since the packaging was squashed, breaking 2 pill pods open inside ( but it was sealed so all good lol) they should've places it in a sturdy box and put fragile so that packaging delivery won't ruin the product. Also, there were no instructions of intake in the box, but I just took it the way I did when I was younger [ please read the company instructions since I'm going by previous experience. So contact them just incase?] Hope this helped! (Highlighter for size reference)
