If you’ve ever checked out the male enhancement products sold in gas stations, convenience stores and elsewhere, you may have come across a variety of pills sold under the brand name “Rhino.”

Rhino pills, as they’re known, claim to offer the usual benefits common to over-the-counter sex supplements: harder erections, extra stamina and better sex overall.

Like with almost all other male enhancement products, there’s no scientific evidence to back up these claims. 

Furthermore, investigations have found that many Rhino brand products contain undeclared and potentially dangerous ingredients. 

Below, we’ve explained what Rhino pills are, how they typically claim to work and the many risks that are associated with these products.

We’ve also shared real, science-based products that you can use to safely treat common sexual performance issues such as erectile dysfunction (ED) and premature ejaculation (PE).

What Are Rhino Pills?

Rhino is a common brand of male sexual enhancement products. Rhino pills are typically sold in gas stations, drug stores and online. 

Supplements sold under the Rhino brand have a variety of names, including: 

  • Krazzy Rhino 25000

  • Platinum Rhino 25000

  • Rhino 30000

  • Gold Rhino 25000

  • Mega Rhino 82000

  • Rhino Blitz Gold

  • Rhino 69

  • Rhino 7

  • Rhino x

Most Rhino pills come in similar packaging, with a distinctive design that’s dominated by a large, holographic rhino. 

Some appear to use similar packaging with alternative brand names, such as “Jet Black™,” “Jet Blue™” and others. 

Rhino male enhancement products are marketed as offering numerous sexual performance and health benefits, such as:

  • Maximizing the time of sexual intercourse

  • Stopping premature ejaculation

  • Maximizing ejaculate volume

  • Providing “rock hard” erections

  • Increasing penis length, width and thickness

  • Making orgasms more intense and explosive

  • Improving sexual confidence

  • “Guaranteed” enhancement

Rhino products aren’t approved by the FDA, nor do they require a prescription. Because they’re cheap, widely available and don’t require a visit to the doctor’s office, they’re often perceived as an over-the-counter alternative to drugs like sildenafil (the active ingredient in Viagra®).

Do Rhino Pills Work?

Like many dietary supplements promoted as male sex aids, Rhino pills as marketed as using a blend of herbal ingredients that claim to naturally improve sexual performance.

For example, the supplement label for Mega Rhino 82000 lists zinc gluconate, horny goat weed (epimedium), white willow bark, black pepper and Rauvolfia serpentina (devil pepper) as active ingredients.

There's no scientific evidence that Rhino pills work, nor is there anything to suggest that the various exotic-sounding ingredients used in Rhino pills or similar over-the-counter products have any positive effects on your sexual performance.

Before we get into the specifics of Rhino pills, let's quickly go over the basics of how erections and male sexual health work.

Erections are about mental and physical stimulation. When you feel sexually stimulated, extra blood flows into the erectile tissue located inside your penis, causing you to develop and keep maintain an erection during sexual activity.

As for your sex drive and general level of interest in sex, it's caused by a wide range of factors, including your body's production of androgen hormones like testosterone, the amount of stress you're under and your level of sexual attraction to your partner.

Most medications for improving sexual performance have a clearly understood mechanism of action. For example, most ED medications work by increasing blood flow to your penis, which can make it easier for you to get and maintain an erection when you feel aroused.

Likewise, medications for increasing your sexual stamina and stopping premature ejaculation either work by reducing sensitivity in your penis or by delaying your body's internal process of reaching orgasm and ejaculating.

As for increasing penis size and length, currently the only real options are surgical procedures, which come with their own significant risks and issues.

Not only is there no scientific evidence that Rhino pills increase your stamina in bed, get rid of erectile dysfunction or enlarge your penis -- there also isn't any reputable evidence that any of the ingredients in them (at least the ingredients on the label) have any significant effects at all. 

Now, this doesn't necessarily mean that Rhino pills can't possibly work at all, or that they don't cause some kind of placebo effect in men who use them.

However, medicine is built around evidence -- both that a specific supplement or medication is effective as a treatment for a specific condition and that it's safe to use. 

Right now, we just don't have any high quality scientific evidence to suggest that Rhino pills or any of the herbal ingredients in them live up to the ambitious claims about sexual performance made on their product labels, or have any real clinically significant effects at all.

Rhino Pill Warnings

However, what we do have is evidence that many sexual enhancement products sold under the "Rhino" brand name contain hidden ingredients, including some that may be dangerous.

Because there are so many different products sold under the Rhino brand name, it’s challenging to know precisely what goes into each capsule.

However, several investigations by the FDA have found that many Rhino pills contain unlabeled ingredients and other substances, including active ingredients from prescription drugs that can't legally be sold in herbal supplements.

Some lab tests have even found that certain Rhino pills contain potentially harmful ingredients that are similar to those that have been withdrawn from the market due to side effects.

In one lab test, the FDA found that the product Rhino 8 Platinum 8000 contained the ingredients sildenafil, N-desmethylsibutramine, phenolphthalein and diclofenac.

Sildenafil is the active ingredient in Viagra. It’s a prescription ED medication that’s only available for people who have been diagnosed with erectile dysfunction by a licensed healthcare provider. 

N-desmethylsibutramine is an ingredient that’s structurally similar to sibutramine -- a controlled substance that was withdrawn from the market in 2010 due to concerns about its safety. It was previously used as a weight loss medication.

Overall, the FDA has identified more than 25 products sold under the “Rhino” brand name that contain undeclared ingredients, often prescription medications.

In response to these issues, the FDA has warned customers not to purchase or use any Rhino enhancement pills or other products.

The FDA has also produced several more general public warnings about over-the-counter sex enhancement pills as a whole. Many of these products, like Rhino pills, are sold in gas stations, sex stores and online without any need for a prescription.

Time and time again, lab testing has revealed that these products are often manufactured with harmful ingredients and unlabeled prescription drugs.

To put the scale of this problem into perspective, a 2021 news release from the FDA found that all 26 of the male sexual health supplements the agency purchased from Amazon for laboratory testing contained hidden ingredients.

Furthermore, 80 percent of the supplements the FDA purchased on eBay contained undeclared active pharmaceutical ingredients.

This is particularly concerning because many of these products are made in facilities that aren't regulated in any meaningful way, meaning ingredients may be contaminated, or the dosages of ingredients (including those that aren't properly labeled) may exceed the safe limit for humans. 

In an announcement from 2022, the FDA stated the following:

"It is clear from the results of our decade of testing that retailers and distributors, including online marketplaces, do not effectively prevent these types of potentially harmful products from being sold to consumers.”

“FDA cannot test all products on the market that contain potentially harmful hidden ingredients. Enforcement actions and consumer advisories for tainted products only cover a small fraction of the tainted over-the-counter products on the market."

Put simply, many of the "too good to be true" male sexual performance supplements sold online are, well, too good to be true. 

Not only do they often use ingredients that aren't supported by any real scientific evidence, but there's minimal oversight or interest in safety from the often disreputable companies that create and sell them.

Our recommendation? Avoid any male sexual enhancement pills, creams or other supplements that aren't supported by real scientific research, and especially any brand that's been mentioned by the FDA as a common offender when it comes to tainted or unsafe goods. 

Risks & Side Effects of Rhino Pills

So, why is it so important to avoid Rhino Pills and other products that contain unlabeled, hidden ingredients? 

The biggest reason is that many of the secret ingredients used in these products can potentially cause side effects and have major safety risks, including the risk of causing drug interactions.

Many of these products contain sildenafil, tadalafil and other ingredients that are typically used in prescription medications for ED. 

These active drug ingredients can interact with other medications and cause potentially serious complications. 

For example, sildenafil can interact with nitrates and other medications used to treat high blood pressure, angina and other cardiovascular health issues. When used at the same time, these medications can cause sudden, potentially fatal drops in blood pressure. 

Other medications for conditions such as heart disease and high blood pressure can also cause interactions when used with sildenafil and other ED drugs.

To lower your risk of experiencing interactions when using FDA-approved prescription drugs for erectile dysfunction, your healthcare provider will ask you about your health status and your use of other medications. 

If a combination of drugs is unsafe, they’ll be able to alert you ahead of time and make changes to your use of erectile dysfunction drugs to avoid adverse events and keep you safe.

Because Rhino pills and other sexual enhancement capsules aren’t FDA-approved prescription drugs, they aren’t subject to the same strict testing and licensing rules. And because they don’t require a prescription, there’s no opportunity for a healthcare provider to assess their safety.

These supplements may be produced in unsafe or unsanitary environments. The hidden drugs used in these products may not be measured accurately, meaning some supplements may use an unsafe amount of these unlabeled active ingredients.

Put simply, these numerous factors combine to create products that aren’t effective, aren’t safe and should never be viewed as replacements for prescription pills for ED or PE. 

Because of these risks, using Rhino pills or other dietary supplements that claim to treat ED or enhance sexual performance is not recommended.

Safer Options for Improving Your Sexual Performance

While Rhino pills and other over-the-counter sex pills aren’t recommended, there are safe and effective options available for treating erectile dysfunction, stopping premature ejaculation and improving your sexual performance.

These include prescription ED medications such as sildenafil (the active ingredient in Viagra), tadalafil (Cialis®), vardenafil (Levitra®) and avanafil (Stendra®).

These medications, which are referred to as PDE5 inhibitors, work by increasing blood flow to your penis. When used before sex, they make it easier to get and maintain an erection while you’re sexually aroused.

Safe and effective treatments are also available for other sexual performance issues, such as premature ejaculation.

These include products such as our Delay Spray for Men, which limits sensitivity to slow down orgasm and ejaculation, and prescription medications such as sertraline and paroxetine, which delay the process of reaching orgasm and ejaculating.

Before using any sexual enhancement products, supplements or medications, it’s important to consult your healthcare practitioner.

Not only can they tell you what works and what likely doesn’t -- they can also make sure you’re safe while using supplements or medication to improve your erections and sexual function.

Understanding the Risks of Rhino Pills

Like other over the counter sex pills and unregulated supplements for male enhancement, the Rhino pills available online and in gas stations aren’t recommended.

Not only are these pills of questionable efficacy -- many contain unlabeled or unapproved drugs that could put your health at risk, especially if you use other medications.

If you’re worried about erectile dysfunction or premature ejaculation, the best option is to talk to your healthcare provider or look into FDA-approved ED treatments.

Unlike Rhino pills, these medications contain exactly what they say on the label, meaning you’ll be able to treat ED, PE and other sexual performance issues with confidence.

We offer a range of evidence-based erectile dysfunction medications and premature ejaculation treatments online, with prescription products available following a consultation with a healthcare provider.
