Hormones of growth 1st edition not revised
Testosterone is the hormone responsible for sexual maturation and dimorphic development of bones and other traits. Higher testosterone triggers puberty, deeper voice and facial/body hair. Amplifies IGF-1 production which is the main reason for growth. IGF-1 is an insulin-like peptide hormone which is produced in the liver and is released in response to HGH. In short, testosterone amplifies IGF-1 production and HGH (Somatotropin) releases it resulting in growth. Production of HGH declines after adolescence, it stops supporting growth but rather supports bodily functions such as maintaining bone density, muscle mass, repair tissue and regulate metabolism.
Dimorphic traits supported by testosterone:
-Deeper voice
-Adam’s apple prominence
-Body and facial hair
-Broader shoulders
-Larger ribcage
-Larger jaw and chin
-More prominent browridge
-Longer limbs to torso ratio
-Fat distributed at abdomen and upper body rather than hips and thighs
-Greater muscle mass, fiber size and strength
-Thicker skin with increased oil production which may increase acne
-Increased competitiveness
-Higher risk tolerance
Traits supported by HGH:
-Height
-Bone size and thickness
-Stronger joints
-Growth of organs
-Increased fat breakdown
-Preserving muscle mass during fasting
-Tissue regeneration

Cortisol is released when stressed and can alter your hormones. To prevent this, learn how to release endorphin which is a peptide hormone that blocks cortisol.
HGH:
-Short term cortisol release can increase HGH especially whilst exercising
-Long term stress leads to smaller pulses of HGH release during sleep
Testosterone:
-Short term cortisol release can mildly decrease testosterone levels temporarily
-Long term stress will significantly lower testosterone levels
Endorphin:
-Short term cortisol release causes endorphin to release as a regulator, it lowers cortisol
-Long term stress will cause endorphin to release less to stimuli due to adaptation
Short spikes of cortisol are not harmful to your growth in any meaningful way. Many actions which cause temporary increased cortisol, such as sprinting, lifting, cardio or sports, decrease long-term stress and are therefore recommended.

HGH:
Somatotropin(HGH) is released in pulses during sleep. Sleep deficiency leads to HGH deficiency which in turn leads to less IGF-1 being released which causes general underdevelopment, like shorter stature or weaker bones.
Testosterone:
Also released in pulses during REM-sleep and lack of sleep will also lead to testosterone deficiency which causes more feminine physical features, less growth during puberty and less bone mass especially for jaw and upper body.
During adolescence you should sleep as much as you can. Aim to be in bed around 10 hours before you have to wake up. Don’t stimulate your brain before sleeping. Exercise daily to ensure you are tired when you go to sleep. Eat and drink enough to not be hungry or thirsty when going to bed (unless fasting).

What is testosterone, HGH and IGF-1?
IGF-1 makes you grow, testosterone makes you grow like a male (dimorphism) and amplifies IFG-1 production (increases bone density), HGH releases IGF-1 and is responsible for your general growth (height, organ size, bone size).
How do I increase them?
Stress less, sleep more and eat well, I will make a nutritional guide soon.
