A note before we start. If you have symptoms of low testosterone — very low energy, low libido, low mood — see your GP for a proper assessment. This article is general information, not medical advice. LifeWave X39 is a non-transdermal, general-wellness phototherapy patch that gently stimulates the skin with light to support the body’s natural energy flow for strength and stamina. It has no effect on hormones claimed or implied, and is not a treatment for any condition.
Testosterone falls gradually with age — roughly 1% a year from your thirties on average — but lifestyle has a big say in where your levels sit. The levers that matter are the same ones that matter for overall health.
Key takeaways
- Sleep is one of the biggest levers.
- Excess body fat, especially around the waist, lowers testosterone.
- Strength training and enough protein help.
- Nutrients help mainly when correcting a deficiency.
- Most “testosterone boosters” don’t work.
Sleep
Much testosterone release happens during sleep. One study found that a week of five-hour nights significantly lowered testosterone in healthy young men. Aim for seven to nine hours. See sleep and longevity.
Body composition
Fat tissue contains aromatase, which converts testosterone into oestrogen, so excess fat tends to lower testosterone. Losing fat while keeping muscle helps. I track composition monthly on a Hume Body Pod.
Strength training and protein
Compound lifts build muscle, improve insulin sensitivity and help reduce fat — all good for hormonal health. I lift every second day with the RP Hypertrophy app and take 10 PerfectAmino tablets a day alongside food.
Nutrients
- Vitamin D — low levels are common; follow official guidance (10µg/400 IU a day in autumn and winter in Ireland and the UK). See vitamin D after 40.
- Zinc — needed for testosterone production; supplementing only helps if you’re low.
- Magnesium — commonly under-consumed.
- Healthy fats — very low-fat diets may lower testosterone.
Stress
Chronically high cortisol tends to go with lower testosterone. Sleep, exercise, time outdoors and breathing practices all help.

Frequently asked questions
Do testosterone boosters work?
Most have little good evidence. No supplement reliably raises testosterone in men who aren’t deficient.
Does losing weight raise testosterone?
Losing excess fat often helps, especially around the waist.
Should I see a doctor?
Yes, if you have persistent symptoms. Low testosterone is a medical diagnosis that needs blood tests.
Does X39 treat any condition?
No. No such claim is made. X39 is not intended to diagnose, treat, cure or prevent any disease.
