    TLDR HSA nanoparticles can improve tamoxifen delivery for breast cancer treatment, reducing side effects.
    The study explored the development of tamoxifen-loaded chitosan enhanced human serum albumin (HSA) nanoparticles to improve the therapeutic efficacy of tamoxifen and reduce its harmful side effects, such as cardiotoxicity and hair loss, in breast cancer treatment. HSA, a highly soluble and biodegradable protein, was chosen for its preferential uptake in tumor tissues and lack of toxicity. The nanoparticles were 137 nm in size with a zeta potential of approximately +15 mV, and demonstrated biocompatibility and safety, as no cytotoxicity was observed with the empty nanoparticles. Under optimized conditions, about 80% of cells were successfully transfected with the HSA nanoparticles, indicating their potential as an effective carrier for anticancer drugs.

      A user shared their 9-month progress using RU58841 at 2% daily for hair regrowth, initially starting at 5% but reducing the dose due to early signs of gynecomastia, which has since mostly resolved. They achieved their goal of regrowing hair at the temples and hairline.

      A 20-year-old started taking finasteride for hair loss at 18, saw improvement, but developed erectile dysfunction (ED) after taking accutane. Despite stopping both medications, ED persisted, and hair loss worsened. Advice given includes considering tadalafil for ED, resuming finasteride, using minoxidil, and addressing psychological factors through positive thinking and lifestyle changes.

      Switching from finasteride to dutasteride and back to finasteride led to gynecomastia and fatigue, likely due to hormonal imbalances. Suggested treatments include Tamoxifen, Raloxifene, or low-dose Anastrozole, with a recommendation to test testosterone and estradiol levels.
