To enhance muscle growth, supplements such as creatine, protein, and polyunsaturated fatty acids have shown consistent benefits in increasing or preserving muscle mass and strength¹. Creatine is particularly well-documented for improving performance in high-intensity exercises, which can lead to greater increases in lean mass and muscular strength².

Regarding height growth, it's important to note that the closure of growth plates typically marks the end of height increase. Unfortunately, there are no well-documented supplements that can delay this process once it begins. Rather than supplements, growth potential is more influenced by genetics and overall nutrition. However, certain supplements like arginine and ornithine have been explored for their potential to increase growth hormone levels, which might have indirect effects on growth during adolescence³.

If you're considering boosting testosterone levels, the evidence supporting specific supplements in significantly affecting testosterone is mixed or unclear. Therefore, it’s important to consult with a healthcare professional before starting any supplement, especially at your age and considering your concerns about growth plate closure.
