Very good for libido and memory, does not leave the person irritated, controls hormones.
Husband using to replace bio-identical progesterone. He felt more libido, more erection, the period is still short, only two weeks, but works well for those who want to increase libido. Improves recall of facts. At first it regulated the hormones, did not make him angry and nor did he give acne as the terrestrial tribulus causes in him. The principle meets the need, we will see evaluations after one month. Would buy again.
