Liquid RU-58841 50 mg/mL Topical For Sale
High-Quality Liquid RU-58841 for Sale
RU-58841 is a nonsteroidal anti-androgen (NSAA) initially 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 or sold at pharmacies.

RU-58841 Mechanism of Action
Sometimes referred to as PSK-3841 or HMR-3841, RU-58841 has a chemical structure similar to RU-58642, a potent antiandrogen that blocks the androgen receptor. It can be applied topically and may be helpful to treat acne, androgenetic alopecia, hirsutism, and other androgen-dependent skin disorders. Sports Technology Labs is the best place to buy RU-58841 online. RU-58841 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 treatment for alopecia. Topical application is widely believed to improve the following qualities in hair:
- Density
- Length
- Hair Diameter
Studies Involving RU-58841
To date, in vivo testing on hamsters and rats has been used to assess the safety and efficacy of RU-58841. The initial results have been promising:
- In one study, researchers transplanted scalp samples from men with androgen-dependent alopecia onto nude female mice. The scalps were maintained for eight months after grafting onto 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 RU-58841-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 one 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 RU-58841’s potential benefits could become available soon. While, as a topical treatment, it is presumed to have fewer side effects than a systemic treatment, it is still new, and side effects are not fully known.

Abuse Warning
Selective androgen receptor modulators are investigational compounds still awaiting FDA approval and are not dietary supplements. At Sports Technology Labs, we are chemical suppliers, not medical doctors, and our expertise is sourcing and quality control. Sports Technology Labs does not encourage or condone consumer use of SARMs products; they are for research purposes only. Anecdotal reports and guides may not match those used in carefully designed medical research protocols and may pose a serious risk of adverse effects in users. Individual variables, comorbidities, and polypharmacy can also contribute significantly to the risk of health problems.
Selective androgen receptor modulators should only be used under the supervision and direction of a medical doctor or designated research authority. We strongly discourage the use of SARMs for performance enhancement in sports and bodybuilding, and warn against “bro science” and peer consensus when making decisions about health.
