Switching to Oestra® is not a one-to-one comparison - it’s a shift to a more efficient, higher-absorption delivery system.
Because of this:
Doses do not translate equally
Even a starting dose can feel stronger
A short adjustment period is normal
Consistency and patience are key—and your body will adapt.
Oestra® stands out because it:
Delivers the highest usable hormone levels due to superior absorption
Provides steady, consistent hormone support
Bypasses the liver, reducing hormone loss and conversion
Is fully adjustable, unlike pellets or injections
