39, day three, and already overthinking the hormone threads

Honestly, hi everyone — I’m brand new here, 39, and I think I’m on day three of this whole journey. I feel a little silly posting because I don’t have a big before-and-after or a neat timeline yet. My only habits so far are one protein shake in the morning and a short walk after dinner, and I’m already reading every TRT and sermorelin thread like it’s required homework. Is it normal to feel like there’s a whole second language around hormones and peptides when you’re just trying to get through the first week? I’m not looking for medical advice, just wondering if I should keep my head down and focus on the basics for now. Thanks for having me.
