what criteria a progesterone product has to meet to be USP grade.
Hi both,
The following quote form the Wellsprings site may be of interest:
Each sealed jar of Serenity Natural Progesterone Cream contains 2.1ozs (60gm/60ml) of the finest quality liposome moisturising cream with not less than 1,260 mgs of USP Pharmaceutical grade bio-identical Natural Progesterone extracted in the USA from plant saponins.
The Certified-Potency Natural Progesterone content (2.34%) has been carefully calculated so those who suffer with the symptoms resulting from unopposed oestrogen can utilise the cream on a schedule which parallels their own body’s natural cycles of progesterone production.
