Bl4ck 4K Review – Do These Pills Have Side Effects?

Bl4ck 4KBl4ck 4k is a sexual health supplement made by Rhino Pills.

For those who have not heard of Rhino, this is a company that releases a lot of sexual health supplements for men.

They tend to get a lot of praise too, but I can’t help but feel that many of the reviews that you find online are fake.

Rhino claims that their product is 100% natural (it isn’t, skip ahead to the third section to find out why).

They claim that they have sourced the best natural ingredients in the world.

These natural ingredients not only help a man to achieve a stronger and longer lasting erection but to also last longer in bed.

This is the ingredient list, although I have no idea how many of these ingredients are truly in the product. I’m willing to wager that very few of them actually are:


  • Goji Extract
  • Cinnamon Bark
  • Dang Gui
  • Licorice
  • Cornus
  • Atractylodes
  • Condonopsis
  • Cordyceps Sinensis
  • Rubus
  • Pueraria Lobata
  • Superoxide Dismutase
  • Vitamin B12
  • Dismutase
  • Cuscuta
  • Deng Sen Extract
  • Panax Ginseng

How Does It Work To Boost Erections?

Throughout this page, I am going to firmly advocate that you do not take Bl4ck 4k under any circumstances (you will discover why in the next section).

However, I am going to be the first to say that it does work.

It does not work due to the natural ingredients, but more down to the fact that it has been formulated in the same way that Viagra is.

Bl4ck 4K will work by stimulating blood flow into your penis.

By doing this, you will be able to obtain stronger and longer lasting erections (I’m not going to go into the science of how this works as it really is not important in the grand scheme of things)

FDA Warnings

When the internet started to take off properly, the FDA started to run into issues.

The internet gave companies the ability to sell their products to the public without going through any sort of ‘checks’.

These companies could make whatever claim they wanted and the chances were quite high that they would be able to shift the product to the masses.

The FDA wanted to cut down on this. It was too dangerous.

As a result, they started to order products in from the internet to see which companies were telling the truth about what was included in their supplements.

One of the products that were ordered in a few years back was Bl4ck 4k.

Now, as we have mentioned previously, the team behind this supplement says that they do not need to conform to FDA regulation because their product is a supplement.

However, it only qualifies as a supplement if it contains 100% natural ingredients.

Guess what, it doesn’t?

The team at the FDA found that Bl4ck 4k contains sildenafil.

This is a key ingredient in Viagra.

This is, of course, a prescription medication.

This means that the retail of Bl4ck 4k is 100% illegal.

Side Effects

One of the problems with prescription medication is that you do need to take it under the watchful eye of the doctor.

This is especially important if you are taking Viagra (or any product which uses the same type of ingredients, including Bl4ck 4k).

This is because the medication can easily interact with certain drugs.

For example; if you are taking nitrate-based medication, then taking Bl4ck 4k could reduce your blood pressure down to dangerously low levels.

This could put your life at risk.

In addition to this, there are some serious side-effects related to Bl4ck 4K which could be life-changing.

Some people may suffer from a heart attack.

Others may lose their vision.

Of course, they are the most dangerous of side-effects.

There are some minor ones which may also pop up.

For example; many of the people who take this drug may experience blurred vision, stomach pain, painful erections, muscle pain, joint pain, headaches, and a whole lot more.

In my opinion, the side effects of Bl4ck 4k are likely to be even more dangerous because you have no control over your dosage of the sildenafil.

In fact, I’m willing to wager that the team that manufactures this product does not really pay attention to a number of ingredients they are putting into the product.

This makes it even more dangerous.

What Is The Legal Status of Bl4ck 4k?

100% illegal. Since this contains a prescription medication, it needs to be authorized for retail by the FDA or whatever the equivalent is in your country.

Since it has not received their authorization, it can’t legally be sold.

Yes. You can buy it online.

In fact, you can buy it online incredibly easy.

However, that does not mean that the product is going to be legal for you to purchase.

Nobody is going to arrest you for purchasing it, but it is still going to be legal to buy.

Anyway, this is something that you probably should not be considering buying anyway.

As I’ve already stated; it is a dangerous product to consume.

Should You Buy Bl4ck 4k?

I’m hoping and praying that you really do not trust the supplement by this point.

Anything which has a prescription medication in it but does not tell you about that prescription medication is dangerous to consume.

That is a fact.

You should not take it at all. Of course, you also have to remember that the team behind Bl4ck 4K actively lied to you about their product.

I don’t like it when companies lie to me.

What else could they possibly be hiding?
