It's true, finding reliable information on peptide dosages can be tricky. What works for one person might not work for another, and it often depends on your individual goals and body composition. I was actually browsing the other day and found this site:
https://misterolympia.to/buy/retatrutide/. It seemed to have some decent information about retatrutide for fat loss and the various products available, though it didn't have explicit dosage advice. However, it might be a good starting point to explore and see what's out there before diving in. Definitely consult with a healthcare professional though!
