AutoShip. No Hassle Automatic Regular Shipments EVERY OTHER Month - One bottle per 2 months (every other month). Progestelle ® is clinically proven and tested since 1999. DOUBLE STRENGTH means you only use one half the amount of oil - less greasiness. You should feel some difference after 10 days - full clinical effect in 3-6 months. Almost without exception after 2 months, IF customers strictly avoid xenoestrogens (chemical estrogens) on the list we give them, our customers feel better. We have been using this list since 1999 and have had good clinical results. You must avoid xenoestrogens for Progestelle ® to work. For severely affected customers, we recommend to stop all xenoestrogens for 1-2 months and THEN take Progestelle ®. This is just an observation not a recommendation. Ingredients: coconut oil, USP pharmaceutical grade bioidentical Natural Progesterone.
