Does Shilajit Increase Size?

The short answer is no. Shilajit does not increase penis size. Shilajit supplements, pills, or resins of any kind available on the market do not have any clinically proven methods for penis enlargement.

If you have searched “does shilajit increase size,” you are not the only one. Every year, millions of men all over the world search for answers to the same question. Most of these men do not know whom to turn to for answers, so they suffer their anxiety, embarrassment, and insecurities.

The anxiety stems from all of the marketing claims from supplement companies that, mixed with a small quantity of curiosity and a lot of insecurity, appear to be extremely convincing.

The anxiety is certainly warranted. Many men spend an enormous amount of money on products that literally do not work due to biological limitations. Many of these products do great harm.

Meanwhile, the evidence-backed benefits of Shilajit Gold, when formulated with genuine Himalayan Shilajit such as its potential effects on testosterone levels and sperm quality, are often overshadowed by misleading enlargement claims.

The purpose of this article is to give you evidence-backed science to support what we say, as well as what clinical trials have been done and what we suggest you do if your real concern is among the following: erectile function, low testosterone, or infertility.

We will keep the science as is and will not soften or exaggerate the benefits. We will present the facts to you.

Now that we have set the stage regarding why many men are concerned about size issues, let us take a look and see what is actually “normal”.

Is Size Anxiety Normal?

Size anxiety is widespread, and most men who experience this anxiety are fully within a typical range the data supports this.

Multiple large studies from 2014-2024 show that many men link perceived smallness to poorer sexual function, anxiety, or body dysmorphic disorder while also showing many men are objectively average in size^[1].

This is worth stating plainly. Having size anxiety means absolutely nothing is wrong with you. Small penis anxiety arises when a man observes his flaccid penile size and feels concerned it is less than normal a concern that often persists even when it has been clinically refuted^[2].

A 2024 study published in the Aging Male journal (Sonbahar, Izmir Katip Celebi University) confirmed a moderately negative correlation between male genital self-image scores and anxiety meaning lower genital self-image is directly associated with higher depression and anxiety scores^[3].

Shilajit benefits for men are one of the most common things searched in correlation with this size anxiety and the reason this is the case is mostly because of how pervasive this anxiety is and how rarely it is discussed.

Concerns about penile size affect self-esteem, sexual function, and satisfaction as well as physical and mental health and these concerns are increasing partly because men compare themselves to pornographic content rather than clinical norms^[2].

How Common Is Worry?

The data shows the numbers are greater than most expect.

What “Normal” Actually Is

The same 2015 BJU International review (Veale et al., n = 15,521)^[4] set out reliable population means:

Measurement	Average
Erect length	≈13.12 cm (5.16 in)
Flaccid length	≈9.16 cm (3.6 in)
Erect circumference	≈11.66 cm (4.59 in)

Most men tend to gather closely around these figures. This research, referring to an earlier Mondaini (2002) study, observed that most men who are in the market for penis enlargement products possess a penis of normal Size. The grievance is of a psychological nature, rather than of an anatomical nature.

Why the Myth Is Risky

Everywhere you look, there is enlargement advertising. The Mayo Clinic directly states^[6] that no pill or lotion that claims to assist enlargement has been proven to help, and many have caused irreversible damage.

The consequence of these products is not just money wasted, but also:

Satisfaction with one’s Size is common among many people in the population, but most of the time these products do not help at all because Size is often normal. Many enlargement products are dangerous and lack evidence of effectiveness.

What about Shilajit? Can this be considered male enhancement, or is there any actual truth to these rumours? Let us address these questions.

What Actually Determines Size – And Where Shilajit Fits In

Adult penis size is determined by genetics and two developmental periods that ‘lock in’ after puberty. Supplements cannot interrupt these.

What Determines Penis Size (and Why Adult Size Is Fixed)

According to Medscape’s clinical reference on treating micropenis, penile growth is not a continuing biological process.

It only occurs during two major phases in someone’s life:

There is a fixed adult size after skeletal and sexual development is complete. Medscape’s reference states that after someone becomes an adult, their penis size is fixed for life.

Testosterone therapy of adult men with normal testosterone levels will not increase the Size of their penis. It is reported that the firmness of erections will improve with therapy, but the organ will not become larger. 

The only exception that has been documented for testosterone causing an increase in Size is when the individual is a prepubertal boy and has micropenis due to a hormone deficiency. This is not a treatment developed for adult men to enhance their penis size.

Penis size is established from an individual’s genetic development and their development in utero and during puberty. No adult penis size can be changed with a supplement.

What Is Shilajit?

Himalayan Shilajit Gummies are a convenient and enjoyable way to consume Shilajit, a herbomineral resin, or “mineral pitch,” that naturally oozes from high-altitude Himalayan rock formations. Shilajit contains fulvic acid, dibenzo-α-pyrones^[8], along with humic substances and trace minerals, which are considered its primary bioactive constituents.

In traditional Ayurveda, Shilajit is regarded as a rasayana, or rejuvenator[8], and has historically been used to support energy, reduce fatigue, promote general vitality, and help with “sexual disorders.” Himalayan Shilajit Gummies provide a modern, easy-to-consume format while retaining the traditional ingredient.

While this historical use provides valuable context, it is not a substitute for modern clinical evidence and should not be interpreted as proof of effectiveness for any specific health claim, including enlargement.

Why Shilajit Cannot Change Size

Pathways that researchers have studied with Shilajit, including mild testosterone support, antioxidant and fulvic acid activity, and mitochondrial energy effects, all lead to dead ends, with no way to achieve longer or wider adult penile tissue. Once it reaches adulthood, that kind of growth is no longer possible.

It is useful to understand why this cannot happen. This prevents concern for money wasted on purchasing Shilajit and the health risks that come with it.

Physical growth of tissues does not occur after puberty. Thus, after puberty, Size is determined by genetics.

Continued hormone levels do not impact tissue size. Since Shilajit does not offer these effects, Shilajit’s studied effects of mild testosterone support, antioxidant and mitochondrial energy effects that are of no significance to adult tissue further support the claim of Shilajit’s ineffectiveness.

Now that we have demonstrated what Shilajit cannot do, it is time to look at what it has demonstrated in clinical trials.

What Shilajit Is Actually Good For

Small clinical trials connect the use of purified Shilajit to supplemental testosterone, improved sperm parameters, and a decrease in fatigue. Each benefit is unique and does not correlate to the Size of the trials.

As you will see in the trials listed below, all were small and a few were short studies as well. The ingredient manufacturers even funded some of these studies. 

Even though Shilajit is not a moonshot by itself, these studies should not be discredited. Rather, these studies should be viewed with caution until larger, more independent studies are completed.

Testosterone Support in Older Men

Pandit et al. (2016, Andrologia) conducted a randomized, double-blind, placebo-controlled study in which 250 mg of Shilajit was administered to men aged 45–55 for 90 days^[9]. 

The participants were healthy men, and Shilajit was administered in purified form.

The results indicated that compared to the placebo, the treatment group had:

Older men tend to have higher testosterone levels, which can positively affect a man’s energy and mood.

However, increased testosterone will not affect a man’s libido or penis size. Increased levels of testosterone in a man’s body are not guaranteed. 

These results were based on a small number of participants, and these studies were funded by an industry that stands to gain financially from them.

It is better to replicate these studies repeatedly until there is substantial evidence to support these claims.

Sperm Quality and Fertility

Biswas et al. (2010, Andrologia)^[11] also conducted a study in which processed Shilajit was administered to a sample of men diagnosed with oligospermia. Shilajit was used at a dose of 100 mg twice daily for 90 days, and 28 of the 35 men in the sample participated and completed the study.

Their findings included:

There was no change in Liver and kidney function tests – a preliminary safety assessment for this dose.

A systematic review and meta-analysis published in 2023 in the Journal of Clinical Medicine on Shilajit and male infertility aimed to evaluate androgen levels and sperm quality.

This study, among the studies reviewed and published, substantiates the most valid and measurable benefit of Shilajit.

Energy, Fatigue, and Exercise Recovery

Fulvic acid, one of Shilajit’s primary components, is associated with cellular energy production.

The Journal of the International Society of Sports Nutrition published Keller et al.’s 2019 study, which used purified Shilajit with an approximate daily intake of 500 mg^[12]. The study documented a decrease in fatigue-related strength decline during the subject’s exercise.

That could enhance stamina and recovery more likely, the main thing men really mean by “performance” supplements is that.

Libido and Erectile Function (Indirect)

Because testosterone impacts libido and erection quality, some mild testosterone support from Shilajit may help desire and firmness in men who are actually low.

However, this is an indirect and unproven way; it is definitely not a direct effect of Shilajit. Men who actually have erection issues should see a clinician and not self-treat.

The effects that most support Shilajit are testosterone support (approximately 20%^[13], small RCT), improvement in sperm count (+61.4%^[11], small RCT), and mild support in energy, all of which are completely separate from and unrelated to Size.

We have now seen what the research looks like. Now, let us see what is effective for the issues that most commonly cause the size issue.

What Actually Works for the Real Concerns

After examining the latest research, it seems that most searches of “does Shilajit increase size” stem from concerns regarding anxiety, erectile dysfunction, low testosterone, or fertility. There are evidence-based solutions for each of these concerns.

If the Concern Is Size Anxiety

The first step is to provide data-reinforced reassurance. Looking back at the Veale (2015) numbers, you are likely within the normal range. Speaking with a partner, a counsellor, or a sex therapist is generally more effective than any product.

If the Concern Is Erectile Dysfunction (ED)

ED is treatable. PDE5 inhibitors, highlighted in the table below, are the first-line treatment. However, patients need a cardiac, hormonal, and psychological evaluation before treatment since these could be the underlying cause. This is not something one can easily self-diagnose.

If the Concern Is Low Testosterone

Do not make assumptions. A medical professional should carry out a clinical diagnosis for hypogonadism before making any decisions regarding the need for testosterone replacement therapy. 

It cannot be used for penis enlargement after adulthood. There are potential health risks involved that should be taken seriously.

If the Concern Is Fertility

See a fertility specialist to get a full workup. There is some supportive evidence for Shilajit and sperm parameters, but it is not a comprehensive fertility treatment.

Evidence-Based General Levers

Mayo Clinic identifies several elements^[15] that genuinely improve male sexual health without the aid of any supplements:

There is a separate evidence-based next step to take for each of anxiety, ED, low testosterone, and fertility, and buying an enlargement product is not one of them.

So, with all that covered, we can move on to the next part of the discussion: how to actually buy Shilajit safely, because this is where the real danger lies.

How to Buy Safe, Purified Shilajit

With Shilajit, the herb is not the safety concern. The concern is heavy-metal contamination. Since Shilajit is an exudate, it can contain mycotoxins and free radicals and may be contaminated with lead, arsenic, cadmium, and mercury.

Consuming contaminated Shilajit can cause poisoning. Shilajit should be purified and must be tested by labs.

Use this buyer checklist when purchasing:

Side-effect note: purified Shilajit has been well tolerated, and dose studies (100-250 mg twice daily) have shown no adverse effects on Liver or kidney function.

However, the data pool is small. Caution is advised for anyone taking other medications, with health conditions, or pregnant women, as a doctor should be consulted.

Claim vs. Evidence – Quick Verdict

Common Claim About Shilajit	What the Evidence Actually Shows
Increases penis size	No scientific evidence shows that Shilajit increases the size of the adult penis. The Mayo Clinic states that no pills or supplements have been proven to enlarge the adult penis.	Myth
Boosts testosterone	A small randomized controlled trial (Pandit et al., 2016) reported approximately a 20% increase in total testosterone in healthy men aged 45–55 after 90 days[13] of purified Shilajit supplementation.	Mild evidence (some support)
Improves sperm count/fertility	A clinical study (Biswas et al., 2010) found a 61.4% increase in sperm count[11] in men with oligospermia following purified Shilajit supplementation.	Strong evidence
Improves libido/erections	No direct evidence shows that Shilajit treats erectile dysfunction. Any improvement in libido or erection quality is thought to occur indirectly through increased testosterone in men with low levels.	Strong indirect evidence
Increases energy and reduces fatigue	Limited studies suggest purified Shilajit (primarily its fulvic acid content) may improve energy production, reduce fatigue, and support exercise performance. However, evidence remains limited.	Plausible; supported by limited evidence
Totally safe/natural	Raw or unprocessed Shilajit may contain heavy metals and contaminants. Only purified, standardized, and laboratory-tested products are considered appropriate for use.	Only if purified and tested

Conclusion

When asked “does shilajit increase size“, the answer is simply no. While some may view this answer as disappointing, the truth is that adult body size is determined by genetics and two stages of development. 

Because of the limitations set by nature, shilajit (or any other resin, pill, or supplement) cannot overcome these biological constraints. The Mayo Clinic states that products marketed for penis enlargement are potentially dangerous, and rightfully so.

While shilajit will not help you as you hope, it has shown positive results in small clinical trials. These studies show that when used in the purified form, shilajit may yield a 20% increase in testosterone with a 61.4% increase in sperm count (in patients with low sperm counts). 

Other studies suggest increased energy and reduced fatigue. These results are positive and are certainly not disappointing.

If your concerns are around the issues listed, then it would be far more beneficial to have a closed-door conversation with your doctor instead of spending your hard-earned cash on shilajit or other non-prescription, potentially harmful supplements. 

Should you decide to use shilajit, only use a product that is purified and is lab-tested. The heavy metal risk associated with unpurified shilajit is a serious safety concern, not just a trivial fact.
