Why 90 days
Sperm development takes roughly three months, so changes made now show up later. That is the logic behind Fathr 90.
Where to start
- Sleep consistently
- Reduce alcohol
- Stop smoking and vaping
- Move most days, without extreme heat exposure
- Eat enough protein, fibre and vegetables
- Get your weight into a healthier range if it is not
