Here's what you need to do. I know because I've been in TRT for 10+years. Always keep yourself hydrated. The day you get your blood work done, drink a ton of water, starting several hours before you get your blood drawn. You NEVER have blood work done first thing in the morning like the doctor says. Why? Because you're dehydrated from not drinking water overnight. You're blood is thicker when you are dehydrated. That throws a false high hemoglobin level. It's not accurate in the morning. You MUST hydrate!
