In Vitro [7-3H]-Testosterone Metabolism by the Rat Ventral Prostate—Effect of Some Exogenous Compounds

The efficacy of degrading the androgen receptor through dermal application in DP cells, a delivery system for topical drugs that involves dissolving microneedles, and rosemary oil as an alternative anti-androgen.

Finasteride may have positive effects by keeping testosterone levels higher, potentially maintaining youthfulness and physical performance as one ages. It could also help with conditions related to aging like andropause and sarcopenia without increasing estradiol levels.

Finasteride has no effect on the user's estradiol levels, and body fat may influence aromatization. The user is on testosterone replacement therapy and uses everyday injections to manage high RBC count, with plans to measure DHT, DHEA-S, and pregnenolone levels.

FCE 28260 (PNU 156765), an under-explored 5α-reductase inhibitor, showcases promising results in research by Giudici et al., outperforming well-known treatments like Finasteride in reducing the conversion of testosterone to DHT. Its superior efficacy, demonstrated through lower IC50 values in both natural and human recombinant enzyme studies, suggests it could offer more effective management of DHT-related conditions. Additionally, its lower molecular weight hints at better potential for topical application, potentially offering advantages in treating conditions such as androgenic alopecia. Despite its potential, it has not advanced in development, possibly due to financial limitations, leaving its therapeutic prospects and side effect profile largely unexplored.

A user experienced unexpected hormone test results after 7 months on 1mg daily finasteride, noting a decrease in estradiol despite expectations of an increase. Other users suggested that hormone responses can vary and that finasteride might still be effective if DHT levels are within range, while also mentioning factors like circadian rhythm and stress that could impact results.
