Hair loss is a significant issue that affects millions of men across the globe.

What’s more, modern science and medicine have yet to discover a definitive cure/treatment for resolving the issue.

It leads to countless men searching aimlessly across the Web for a reliable solution.

Fortunately, RU58841 may offer hope compared to other hair loss products that have let you down in the past.

The substance, also known as PSK-3841 or HMR-3841, is classified as a non-steroidal antiandrogen (NSAA).3

RU58841 is believed to prevent dihydrotestosterone (DHT) as well as other androgens from binding to receptors in the hair follicles.

In other words, RU58841 promotes healthy hair by enabling follicles to grow under natural, unrestricted conditions.

The drug was originally developed by French scientists in the 1970s to combat hair loss and skin conditions.

However, it has yet to receive the same acknowledgment and support from The Food and Drug Administration (FDA).

It’s unfortunate considering that one NIH study found enough supporting evidence to encourage more clinical trials.4

Nevertheless, more studies are necessary before experts can reach a sound conclusion on RU58841 as well as the conditions it may treat.

Benefits of RU58841

RU58841 has been in existence for decades despite resistance from the FDA.

Consequently, most of its reputation has been earned by word-of-mouth endorsements and reviews.

Nonetheless, the reported benefits of RU58841 are both impressive and optimistic for treating hair loss in the future.

The non-steroidal antiandrogen (NSAA) is believed to prevent androgens like DHT from binding to receptors in the hair follicles.

As a result, the NSAA promotes healthy hair by not restricting hair follicles from their natural production.

In addition to preserving current hair follicles, RU58841 also stimulates new hair growth.

Additionally, the NSAA is linked to treating acne and other skin conditions like hirsutism and androgenetic alopecia.5

RU58841 improves several aspects of your hair, including:

  • Density/Thickness
  • Length
  • Durability

Unfortunately, finding pure and reliable RU58841 is not always straightforward.

Furthermore, since the substance is not approved by the FDA, it’s not available over-the-counter or with a prescription.

Thus, you should consider shopping for RU58841 powder at Sports Technology Labs.

Sports Technology Labs independently tests its RU58841 to maintain high purity and consistency standards.

Moreover, unlike most suppliers, each purchase includes a Certificate of Analysis to confirm you are getting the real thing.

How Long Does It Take to See Results?

RU58841 features a chemical structure comparable to RU58642 – another powerful antiandrogen.

Both of these antiandrogens are effective at reversing processes of aging as well as promoting healthy growth.

Thus, there is limited clinical research to support RU58841 for treating hair loss and skin disorders (like acne).

RU58841 has an especially strong word-of-mouth reputation since it has been around for decades.

You can find a wide variety of suppliers online that sell RU58841.

However, that doesn’t make all suppliers of RU58841 equal since many deceive their customers with cheap, knock-off alternatives.

For this reason, you should only buy from a reliable manufacturer that third-party tests all of its antiandrogens for quality.

Furthermore, you should only buy from suppliers that are willing to produce a Certificate of Analysis confirming the purity of the substance.

It will make you a smarter customer when you start shopping for RU58841 online.

More importantly, buying pure and reliable RU58841 will deliver stronger results.

There are varying opinions on how long it takes to witness results from RU58841.

In general, most notice improvements in hair growth within 2-4 months with regular use.

While the results may vary widely, several studies (more information, below) support the use of RU58841 for treating hair loss.

The below Youtube video does a pretty good job of explaining when you would see the results: 

How Does RU58841 Work?

RU58841 is a non-steroidal antiandrogen (NSAA).

In other words, it’s an androgen receptor antagonist or “anti-androgen”.

If you view the body as a fight between good and evil, antiandrogens are actually the good guys in terms of hair growth.

They prevent harmful androgens like dihydrotestosterone (DHT) from disrupting normal hair growth.

These androgens not only bind to hair follicle receptors but also trigger a chain reaction that amplifies the process over time.

Consequently, RU58841 is intended to prevent hair loss as well as stimulate new growth/repair.

Furthermore, the chemical increases cellular proliferation and replication which is necessary to restore your hair to its previous health.

More importantly, RU58841 does not appear to produce any negative effects on body hormone levels while treating hair loss.

You can learn more about how RU58841 works by studying its cousin – RU58642.6

Side Effects of RU58841

The side effects of RU58841 appear minimal and not significant.

However, information is limited since the substance remains unregulated outside of the FDA.

Thus, most rely on word-of-mouth reputation and online reviews to determine if RU58841 is safe.

It’s unfortunate yet the reality for most suffering from hair loss.

In general, the side effects of RU58841 are well-tolerated and not life-threatening.

Since the NSAA does block androgen receptors, it may also reach the bloodstream and impact issues like low libido or erectile dysfunction (ED).

It may also impact fatigue in some users, especially those new to supplementing RU58841.

The good news is that the limited research related to RU58841 is promising even if currently restricted to test animals.7

Still, research is ongoing and more is necessary to make a final determination on the effectiveness of RU58841.

How To Use RU58841

RU58841 is available in liquid or powder form.

The method of intake may depend on if you are using RU58841 for hair growth or treating a particular skin disorder.

In general, most apply RU58841 as a topical agent (directly to the scalp) or digest it orally through a powder substance.

The typical starting dose is 50mg while some users bump the dosage to 75-100mg per day.

We suggest starting with a smaller dosage and monitoring side effects before adjusting to a higher number.

Also, speak with a physician before use if you currently take other medications.

RU58841 does not produce rapid, immediate results.

Rather, you need to exercise patience and apply it daily (just like with any other type of supplementation).

It can take 2-4 months to notice improvements in hair loss yet some report changes in as little as 4 weeks.8

How To Get the Best Results

There are several suggestions for achieving the best results with RU58841.

For starters, only purchase from a reliable manufacturer that is willing to share its Certificate of Analysis.

Also, avoid any supplier that refuses to third-party test its formula for purity and consistency.

You would be shocked at the number of suppliers that advertise RU58841 which is not actually legit.

Secondly, determine a method of application and correct dosage.

RU58841 powder is reliable because you can mix it into your own solution for daily supplementation.

Third, starting with a low dosage (30-50mg) will avoid producing any serious or harmful effects.

You need to exercise patience and allow your body time to counter the negative effects of androgen receptors binding to your hair follicles.

Notwithstanding, patience does pay off as RU58841 can save your hair with the proper administration.

Lastly, stacking RU58841 with other substances like Minoxidil may accelerate hair growth and prevent hair loss.9

There are plenty of options for stacking including solutions for combating low libido and ED (two side effects of RU58841).

Does RU58841 Work?

RU58841 is an experimental drug that has yet to receive approval from the FDA.

Regardless, the word-of-mouth reputation is worthy enough for some to experiment with the antiandrogen.

While human trials are still lacking, limited evidence supports using RU58841 for hair loss.

The study conducted on female mice witnessed remarkable improvements in linear hair-growth rates (LHGR).

More importantly, RU58841 has reached Phase 3 in clinical trials which demonstrates it has the potential to serve as a safe, effective remedy.

Be that as it may, research is ongoing, and more is necessary to receive approval from the FDA.

Who doesn’t want to return to their former glory?

For men, there are few characteristics of the body that matter more than hair, especially when it starts to vanish.

Hair loss can contribute to low self-esteem and confidence, particularly when it occurs at a younger age.

Fortunately, you do not have to settle for what would have been an inevitable aspect of aging in the past.

New science and medicine are leading to impressive discoveries, including remedies for hair loss.

RU58841 is a non-steroidal antiandrogen (NSAA) that combats the effects of damaging agents like DHT.

It has the potential to reverse hair loss as well as stimulate new growth.

Consequently, you can return to that former glory with a scalp of hair anyone would be proud of.

The positive results of RU58841 are especially noteworthy when you shop from a reliable manufacturer and supplement properly.
