Are you taking this ??? Boron is one of the most androgenic 'natty' supps out there, tons of people tend to feel it's androgenic effect more than Fadogia, Tongkat and so on.... Most of the time, This androgenic effect is attributed to: 1 increases Free T by lowering SHBG 2 reduced aromatization of Test → Estrogen 3 enhanced Test → DHT conversion (through 5ar) But one of the more interesting mechanism would probably be it's effects on the metabolism itself and how that further promotes steroidgenesis. Boron doesn't have a RDA, because it's not seen by the mainstream as something humans 'need for biological function', but Boron deprivation in animals has been shown to cause deficits in insulin sensitivity through preventing β-cell deterioration one small study (n=8) on healthy male human adults showed that 10mg a day for 2 weeks lowered hs-CRP levels with 50% on average, a biomarker strongly associated with insulin and leptin tolerance. Tons of papers show the connection between Boron supplementation improving bio-markers indicative of Leptin tolerance, we lack big high-quality studies on Boron it's effects on metabolism, but almost all small studies are fairly consistent with their results. Tons of papers also show low-Boron diets to cause an increase in bio-markers of Leptin resistance. Boron it's effects on improving leptin and insulin sensitivity is likely another way through which Boron produces these 'androgenic' effects many people describe from supplementation of it as well as libido. Leptin plays a MASSIVE role in steroidgenesis and the HPG axis through a special pathway: Leptin → Melanocortin → Kisspeptin Boron improves metabolism → Leptin sensitivity → Leptin stimulates α-MSH release → α-MSH skyrockets libido by binding to MC3R and MC4R → α-MSH & Leptin stimulate mRNA expression of Kisspeptins → Kisspeptins kickstart steroidgenesis through GnRH This could also explain why Boron has such different effects between men and women, Boron supplementation increases serum E2 in women, but strongly reduces it in men.
