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

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.

A user on Finasteride for 7-8 years reported unexpectedly high testosterone levels despite expecting lower levels due to age, with discussions on the impact of SHBG and suggestions to use boron to lower SHBG. Another user noted that Dutasteride significantly increased their testosterone and free testosterone levels.

Pyrilutamide and RU58841 are androgen receptor antagonists that block receptors without significantly reducing testosterone or DHT levels. Any indirect effect on androgen levels is likely negligible.

Finasteride may affect male offspring's fertility and hormonal balance, with debates on whether to discontinue use before conception. Some users report no issues, while others highlight the high doses used in rat studies.

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.

RU58841 is absorbed systemically in humans, contradicting claims it stays local, but no harm is proven. Alternatives like CB-03-01 or KX-826, especially with finasteride, are suggested for safety.
