  •  
    Study finds injectable contraception in men leaves delayed suppressed LH and Testosterone. This drug design is by those devoid of overall knowledge of physiology. Lower Testosterone in men has significant negative metabolic effect, neurotransmitter impact, and what about epigenetics. Some men have epigenetically increased risk of hypogonadism. This contraception is a bad idea physiologically.

    Birth control pills were found to reduce IGF-1 levels in the short term and long term.  Those that had used birth control pills had lower IGF-1 levels compared to those that had never used birth control pills.  This fits with the current knowledge that oral estrogen reduces HGH and IGF-1.  Those were in post-menopausal women, but this is in pre-menopaus women.  This has implications on health, weight, disease...
