Sleep is testosterone's best friend
Sleeping only 5 hours reduces testosterone by 10-15%. One study showed that men sleeping 4 hours had testosterone levels of a man 15 years older.
Total T is the wrong test
Total testosterone misses the picture. Free testosterone — the unbound, biologically active fraction — and SHBG (the binding protein) tell you what's actually reaching your tissues. Always draw between 7-9am, fasted; T peaks then and declines through the day.

Key Takeaway
Lift heavy, sleep deep, manage stress, and maintain healthy body fat. These four habits preserve testosterone better than any supplement.
