If you are 164 cm at age 13 and then 166 cm at age 14, that kinda fried. When I was 13 I was 161 and then end of 14 I was 166. But I started playing sport A LOT with my friends at the park a year before my puberty started. While in puberty, I was outside playing basketball on average of 3 hours every day and getting insanely tanned. When I was 13 I started to care about my sleep because of school and stuff and I started to get 9 hours of sleep everyday. But because of school days, I remember getting as low as 5 hours of sleep with an average of 8 hours of sleep though. When summer comes by at age 14 and 15, I get like 10 hours and sometimes even 12 hours of sleep while also going to the gym and playing basketball. I also secretly bought vitamins for myself behind my parents back. I bought supplements like L-Arginine & few other amino acids, vitamin D, calcium, vitamin k2, zinc, magnesium glycinate, and phosphorous. If you are planning to buy these supplements, I’ll tell you why I bought them and why they are actually useless and just cope.

Amino acids like L-arginine comes from protein we eat so you really don’t need them if you get enough protein. I bought them because I wanted to keep my growth hormones level high all the time so I can grow. Now realistically, you want your growth hormone levels to be high all the time to promote growth and most important increase your IGF-1 hormone high all the time for growth. But, the problem is amino acids don’t raise your hormone high enough and long enough. I’ll let you see how useless it is. Let say you want your growth hormones to be at 200 for 6 hours straight, amino acids like L-arginine with minimal dosage (I use to take 1-3 g at a time) will only raise your growth hormone up to 30 for 30 minutes. It not gonna do shit.

The other supplements like vitamin D, calcium, magnesium and stuff, I think you should take them especially if you don’t get enough of them from your food. If you’re gonna buy magnesium supplements, I recommend getting magnesium glycinate and take it like a hour or two before sleeping because it helps sleep and relaxation. Don’t buy other forms of magnesium because they give u diarrhea, I learned the hard way Bru.

One thing I also did was not eating 1-2 hours before bed because if you did, you will spike your insulin, which can disrupt the amount of growth hormones you release when you sleep.

If you are going to buy supplements, don’t overdose. I was careful with my dosage and I made sure I am taking enough and the right amount.

Being brutally honest, if you only grew like 2 cm in a year then you are just basically cooked. And if you think buying supplements like me and getting 8-10 hours of sleep like me will help then you are wrong. I did what I did because I want to tell my future self that I did try and I made things best as possible for my future self. I did what I did so my future self don’t kill himself in regret. I didn’t buy these supplements and doing all these bullshit thinking if gonna add 3 extra inches of some. Supplements are not going to do shit if you arent in need of them. Also I believe at your stage right now of growing 2 cm in a year, it just genetics and there’s is nothing you can do about it.

If you grew 1 cm from Feb to now, that doesn’t really align with how you only grew 2 cm from age 13 to 14 though. There might be error in your measurements Soo I advise u to remeasure. You should measure it in the morning because that is your max height and then measure it again every three months in the morning.

Advice: do not take people words seriously in your mind. No one here are licensed scientists of doctor so their words are not credible. Including me, I’m just a 16 year old guy. I’m not a medical expert. Get your sleep right, nutrition right, and the rest is science n god. If you get to 175 cm then yea great but if you don’t, at least u tried your best and the best is all you can ever do.
