Thank you so much for sharing! Took 600 mg most days last winter. THIS explains the sky rocketing Testo level that was found in spring. As a female in early menopause this completely threw me off to the point I lost my job. Also as Estradiol was below the gaugeable range for at least three months. Assume this excess Testo took a role in "lowering" 😀the non existing Estradiol. Thank god my doctor is US trained in nutrition, vitamins and hormones (which is like finding a pot of gold when in Germany), I am on my way back. After 4 months Testo level has lowered a bit but is still way above the upper limit. Estra and other hormones are now perfect, thanks to HRT.
