I found out about Doctorplus and bought for my twins when they were 12 (they are 16 now). Both grew up so fast and so tall, taller than their dads and grandpas. This product is the only natural supplement for height growth that I trust to give my precious children. They want to become models when they grow up so that's why I gave them this product in the first place. Till my best decision!
10-18 I guess .. heard that you can't grow taller after 18 but not 100% sure
From 10 yo, but if you are 18 yo, it's best to consult your doctor's advice bc when your growth plate closes, you cannot grow taller.
Teens only i guess. Adults can't grow even with magic capsules
