Testosterone peaks in the early morning after a full night of sleep. One week of 5-hour nights lowered T by 10–15% in a University of Chicago study — the equivalent of ageing a decade.
Untreated apnea is one of the most common hidden causes of low T and low energy in men over 40. Loud snoring plus daytime sleepiness warrants a sleep study.
Fixed wake time, dark cool room, no alcohol within 3 hours of bed. Then, and only then, consider a supplement like Maxorin.
