It started with feeling flat
I was sleeping enough, eating reasonably, and still dragging. That question sent me down a long reading path.
What I learned first
Most of the answer was boring: protein, sleep, strength training, and daylight. The unglamorous inputs did the heavy lifting.
Where the research reading came in
Once the basics were in place, I got genuinely curious about recovery and longevity research, including published work on peptides.
How I keep it honest
I separate what I have personally tried from what a study says, and I do not give medical advice. If something interests you, bring it to a clinician you trust.
