Is there a topical peptide for hair growth?

I’ve personally spent time researching GLP-1 pathways (Reta / Tirzepatide class) and mitochondrial support (MOTS-C, NAD+). What stood out for me wasn’t “fast weight loss”…It was things like: • steadier appetite 🍽️ • less energy crash mid-day ⚡ • better recovery between sessions 💤 Curious how this lines up with others here 👇Have you researched GLP-1s, MOTS-C, NAD+, or something else from the shelf? 👉 What was the first thing you noticed working (or not working)?
