When most guys start thinking about using a male performance enhancing supplement, they’re looking for something that works like Viagra – quickly and effectively.

They don’t want to have to remember to take a pill every day like it’s medicine.

They just want to pop a pill or two when the time is right and know that they’ll be legendary.

That’s what Black 4K claims to do for you.It’s the newest in a long line of supplements from the Rhino brand (at least I think it’s the newest – it can be hard to keep up).

And that brings up a valid question – if any of these products worked, why would the company keep replacing the old versions with new versions?

If it worked, wouldn’t they just stick with it?

Well, maybe.

I’ve looked into it and I think I have the answer, but we’ll get to that in due time.

First, lets take a look directly at Black 4K and see what it can and cannot do.

to jump to my personal review.

Black 4K Benefits

Like we mentioned up above, Black 4K is a take-as-needed male performance enhancement supplement.

You don’t need to take it every day, just one pill about an hour before you’re ready to have sex.

What happens is you’ll:

  • Achieve your erection practically at will.
  • See your hardest, thickest, longest erections ever.
  • Last longer than you thought possible.
  • Have zero concerns about premature ejaculation.
  • Explode in the end with massive amounts of ejaculate.

And it claims to do all of this using a completely herbal formula that we’ll take a look at now.

Black 4K Ingredients

The ingredients in Black 4K are all listed in a proprietary formula on the product packaging.The fact that it’s proprietary means that they’ll tell you what ingredients make up the formula, but they won’t tell you how much of each there is.

Here’s the list they provide:

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

Click Here to see a picture of the label.

There are only a couple of familiar ingredients in the list, including Goji Berries, Panax Ginseng, and Vitamin B12, which may all be decent supporting ingredients in a strong formula, but can’t carry one on their backs.

Goji Berries are an aphrodisiac.

Ginseng provides energy and some libido support.

And Vitamin B12 gives you lasting energy.

Again, all good components, but not enough to make a very effective formula on their own.

A little research into the others shows that Dang Gui supports healthy blood flow and Condonopsis is an energy booster.

But on the other hand, Licorice and Rubus should not be used as sexual enhancements for men. Licorice can lower your libido, and Rubus has an estrogenic effect, so we’re not sure what these two are doing in the mix.

All in all, I’d say the formula looks quite weak.

If it works like they say, I would be surprised.

I have some on order, so after I check it out, I’ll come back and post my results.

Black 4K Review Black 3KBlack 4K vs Black 3K

We did a review for Black 3K, the previous version of Black 4K, and surprisingly there’s very little difference between the formulas. The only difference I could find is that Black 4K contains Vitamin B12, whereas Black 3K left that out.

Black 4K Reviews

For a new product, there are lots of customer reviews posted on Amazon.com, where the range of opinion varies a great deal, and it’s a relatively even split.

A large percentage of reviewers give Black 4K 5 stars, but an almost as large percentage give it only 1 star.

The rest fall somewhere in between.

A typical 5-Star Review looks something like this one from “Amazon Customer”:

“Wow this stuff really works.

One capsule lasted over seven days….

Awesome!”

The typical 1-star review basically states that Black 4K just doesn’t work, but they often compare their results to Black 3K:

“I’ve bought 3K before, That worked wonders, Not sure whether this is counterfeit garbage or 4K sucks overall, but this stuff does absolutely nothing”.

“I had tried the Black 3K before and had great results, Don’t really know what the difference in the two are”.

Is Black 4K Better Than Black 3K?

As far as we can tell, Black 4K and Black 3K have almost the exact same stated formula, the only difference being a little Vitamin B12. Of course, they may have played with amounts, and since we don’t have that information, we don’t know, but I have a different theory.

Rhino male enhancement products frequently get recalled when the FDA discovers that they contain undisclosed ingredients – most often and most notably Sildenafil, the active ingredient in Viagra.

It’s something that a lot of these fast acting enhancements do.

They inject a little of the stuff that works into each pill without letting anyone know (because it’s illegal), then they pass themselves off as all natural so they can sell it over the counter.

It’s sort of a double-edged sword.

Now all of a sudden the product works, but it’s no longer an herbal supplement and it could potentially be dangerous for some guys to use.

If you take heart medication or blood pressure medication, you should stay away from Viagra, and by extension, Rhino products.

Even if you don’t have a heart condition, do you want to trust a company and take their pill when you know they’ve been dishonest about their ingredients several times in the past?

Is Black 4K Safe?

Usually, it’s fairly easy to spot potential offenders.

Customers who’ve used it will complain of headaches, stuffy noses, and racing heartbeats.

These are common side effects from Viagra.

If you see feedback about a “natural enhancement supplement” and they mention these, it’s a pretty good sign that there are undisclosed ingredients involved.

The “good” news is the Black 4K feedback doesn’t say this at all.

Instead, they just say it doesn’t work, which leads me to believe it doesn’t have the Sildenafil in it (at least not yet).

Since it’s a Rhino product and they get so much attention, I’m planning to test this one myself.

I’ve used Viagra before, and I’ve taken pill that turned out to be more than just supplements in the end, so I know what to look for and will be able to tell you whether or not Black 4K is on the up and up or just as shady as the other Rhino supplements.

My Personal Results

black 4k reviewI finally got a chance to try out Black 4K, and I have to say I’m quite impressed.  It’s not the best fast acting male enhancement pill I’ve used (click here to see that one), but it seemed to get the job done.

For me, it seemed to start working in about 30 min., and the effects were pretty good.  I experienced relatively rock hard erections, and it definitely gave me a marked improvement in libido.

One thing I did notice was one of the side effects I got from it was a REALLY bad headache.  I can’t be absolutely certain that Black 4K was responsible for it, but I didn’t take anything else that day and I don’t normally suffer from random headaches.

Another random thing I seemed to notice was it made me tired.  I’m not completely sure that Black 4K was the culprit, but I was in bed about 1 hour before I normally would be that night.

Update 12/23:  Black 4K Contains Hidden Ingredient

It’s been a long time since I’ve done a follow up review for Black 4K, but I just so happened to come across the FDA website and found out that they’re actually putting an illegal ingredient into their supposed all natural formula.

It’s called Sildenafil, and it’s the active ingredient in prescription ED medications.

This would explain why it works as well as they say it does, and also explains why I got a headache from taking it.

Where to Buy

Black 4K is available online through a bunch of different retailers, and I know some of them sell to convenience stores and sex shops, so you might be able to find some out in the world too.

It’s sold in single packs for around $8 a pill, including on Amazon.com.

Look around for your best price.

Black 4K Pros and Cons

Advantages of Black 4K

  • You don’t have to take it every day.
  • The ingredients appear to be all natural.
  • Since you buy it in single packs, it doesn’t cost very much to try.

Disadvantages of Black 4K

  • Black 4K reviews are not very promising as far as how effective it is.
  • It’s made by Rhino, which is making quite a name for itself in the business of trying to sell medication as supplements.

Conclusion

At this point, it looks like Black 4K is indeed all natural, but that it doesn’t work as advertised.

In the end, the reason Rhino puts undisclosed ingredients in their formulas is because they work, and people are willing to risk the potential side effects for the potential success.

And without the prescription medication, a fast acting herbal formulation doesn’t have much of a shot.

Since personally testing it, I agree, it actually does work.  However, the fact that they MIGHT be putting illegal ingredients in it knocks down my overall rating quite a bit.

Hi, I have 2 questions.  1- Can I take Black 4K with Alcohol and 2- Can I take Balck 4K before 2 or 3 hours before sex?  Thanks. -


Alcohol in moderation shouldn't be a problem, and 2 or 3 hours before sex is probably fine. You want to shoot for an hour before, but 2-3 hours should work just fine.- Rob

Can you take Black 4K daily? -


If it truly doesn't contain undisclosed ingredients, then it would be safe to take daily. But at $8 a pill, I wouldn't recommend it.  If you're looking for a pill to take daily, the best is VigRx Plus.- Rob
