**I am writing this thread because I know a lot of people especially teens want to increase their IGF-1 and GH levels without possibly causing irreversible damage to their body and/or hormone levels.**

Free GH for males (A) and females (B) expressed as the delta values for the peak changes pre- and post-exercise relative to baseline values. * Significantly different from placebo (p < 0.05). † Significantly different from the corresponding values for females (p < 0.05)

1. Diet and nutrition
Protein intake - sufficient and quality protein intake is necessary for your body to produce IGF-1, Include lean meats, eggs, dairy, and organ meats in your diet. Follow the 80/20 rule, eat 80% healthy and 20% whatever slop you crave take cheat meals not cheat days, this helps keep a stable diet and prevents crashing and binging on slop. You'll want to hit around 1g of protein per pound of body weight (1g per .45 kg for non-Americans).
Zinc - Zinc is essential for IGF-1 synthesis the recommended intake for men is 11mg of zinc you can achieve this daily by taking multivitamins with zinc and/or zinc supplements make sure you don't take too much, or you can possibly become deficient in copper which already 25% of American's are, you can prevent his by taking copper supplements at a different time from your zinc supplements because they fight for absorption.

2. Lifestyle and activity
Sleep - Sleep is one of the most if not is most important factor for maintaining and/or increasing GH and IGF-1 levels. GH and IGF-1 secretion occur predominantly during deep sleep. Ensure 8–10 hours per night during puberty. to increase sleep quality take 250mcg of melatonin daily, more than this can mess with your natural melatonin production.

Exercise - High intensity training triggers GH release because your pituitary has to repair muscle damage. Multiple studies back this up (Haff & Triplett, 2016; Hoffman, 2014). Aim to train at least 4 times per week and walk 10k steps daily. More intensity and longer sessions = better GH response.

TL;DR
Eat enough protein (~1g/lb bodyweight), Eat mostly clean but 20% can be slop.
Get 11mg of zinc (supp or multi) but balance with copper to avoid deficiency.
Sleep 8–10 hrs, deep sleep = peak GH/IGF-1. Tiny melatonin dose (250 mcg) can help.
Train hard 4+ days/week + 10k steps/day = good GH release.
