High Quality Liquid RU 58841 for Sale

RU-58841 is a nonsteroidal anti androgen (NSAA) originally developed by French scientists in the 1970s. It is believed to stop dihydrotestosterone (DHT) and other androgens that cause androgenic alopecia from binding to receptors in the hair follicles, allowing hair to grow normally.

The Food and Drug Administration (FDA) has not approved the use of RU-58841, and it cannot be prescribed and sold at pharmacies. 

RU 58841 Mechanism of Action

Sometimes referred to as PSK-3841 or HMR-3841, RU58841 has a chemical structure similar to RU58642, a potent antiandrogen that blocks the androgen receptor. It can be applied topically and may be useful to treat acne, androgenetic alopecia, hirsutism, and other androgen-dependent skin disorders. Sports Technology Labs is the best place to buy RU 58841 online. RU58841 should be stored at room temperature to maximize shelf life.

RU-58841 is believed to promote hair growth and is being studied in clinical trials as a topical anti alopecia agent. Topical application is widely believed to improve the following qualities in hair:

  • Density
  • Length
  • Hair Diameter

Studies Involving RU58841

To date, in vivo testing on hamsters and rats has been used to assess the safety and efficacy on RU58841. The initial results have been promising: 

  • In one study, researchers transplanted scalp samples from men with androgen-dependent alopecia on to nude female mice. The scalps were maintained for eight months after grafting on to the mice, with monthly monitoring for six months. The grafts treated by RU-58841 produced 29 active follicles, eight of which (28%) showed a second cycle. Also, the values for the linear hair-growth rates (LHGR) were higher in the RU58841-treated group.
  • Researchers synthesized RU-58841 and discovered it has a high affinity for the hamster prostate and flank organ (F.O.) androgen receptors. When RU-58841 was topically applied in vivo, it delivered a potent quantity-dependent regression of the F.O. area at a dose as low as 1 microgram/animal. Furthermore, in intact rats, no side effects of RU 58841 were observed up to 1 microgram/animal.

RU-58841 research is ongoing. More studies that highlight RU58841’s potential benefits could become available soon. While as a topical treatment it is presumed to have less side effects than a systemic treatment it is still new and side effects are not fully known.

RU-58841 FAQs

Data suggests that RU58841 may mitigate symptoms of male pattern baldness (alopecia) by antagonizing androgen receptors when applied topically to the scalp. More research is needed to determine the safety and efficacy of RU58841

RU58841 is chemically similar to Finasteride, the difference however is that RU58841 was designed for topical application while Finasteride is prepared for oral administration.

RU58841 is a nonsteroidal anti-androgen that blocks DHT, testosterone, and other androgens from binding to the androgen receptor without reducing circulating androgen levels.
