Do more research into HGH before taking. It stops your natural production. They recommend it to 40+ year olds when IGF-1 levels go below 100. If you're ok with running it for the rest of your life, by all means dive in head first. Otherwise there is plenty other ways you can cut fat. Don't worry about height if it's going to impair the rest of your life lmao. People can be fucking retarded tho so up to you bro. I guarantee at your stage in life if you do 10-12k steps a day on 1800 calories (1500 is relatively low if doing exercise), prioritise 2.2g per kg/1lb per lb bw protein, resistance training/weights/gym in general youll have no issue. use Chatgpt to create a basic program and watch basic youtube videos to help you learn form for exercises. Get foundations right and in 6 months youll laugh. I lost 20kg/44lb in 6 months by not eating shit and training 4x a week 60-90mins.
