What they REALLY do best is separate people from their money.
No, the only thing that is known to make people grow is HGH, Human Growth Hormone. But it's quite dangerous and shouldn't be used except in extreme circumstances and only under a doctors supervision.
I have been taking Peak Height Height maximizer for 2 months or so now and when i started i was 159cm tall and I am now 166cm tall... Im not sure if my stats are having an affect on my growth, i am turning 17 in around 4 months and I am probably due for a growth spurt, also Im female.... mmm not so sure if its the tablets or just mother nature, but I have noticeably grown taller... the tablets have all the ingredients and everything seems pretty safe, no side effects thank god.... hope this helps.
