community Androsterone as a Neurosteroid Replacement Strategy for 5α-Reductase Inhibitor–Associated Sexual and Affective Dysfunction
Androsterone may help with sexual and affective dysfunction from finasteride by replacing disrupted neurosteroids without increasing androgenic side effects. Controlled testing is needed to confirm its effectiveness and safety.
community Latest study on RU58841 done 19. August 2026.
RU58841 can be absorbed systemically after topical application, but the study did not find immediate hormonal disruption. The study highlights the need for more research on long-term safety and effects of RU58841, as well as the importance of quality control in products from the grey market.
community Weed/THC effects on hair growth/hair loss, and vitality of organ-culture human follicle studies (research review)
Cannabis and THC may have mixed effects on hair, with some studies suggesting potential negative impacts on hair growth in isolated hair follicles, but these results are hard to apply to living humans. Treatments like minoxidil and finasteride are commonly used for hair loss, and the effects of cannabis might be neutral or vary based on individual factors.
community My Theory Of Androgenic Alopecia
Hair loss is linked to cellular physiology and the IGF-1 to TGF-B1 ratio, not just androgen sensitivity. The theory lacks evidence, while finasteride and minoxidil are effective treatments.
