Black 3K Overview

With so many players in the male enhancement supplement market, you’re bound to run into some that might be not so on the up and up.

A budding entrepreneur gets an idea that he can produce and sell a supplement on the cheap, and voila, a new contender is born.

Every time we come across a product we haven’t seen before, we necessarily approach it with this in mind.

It might be perfectly legit, but then again it may not.

So we look at each of them with fresh eyes, with the goal of finding the truth.

Black 3K is a male enhancement supplement you can find online. Sometimes you’ll see it listed as Rhino Black 3K.

It’s the kind of fast acting pill that everyone wants, something that can replace Viagra and the other prescription pills.

By simply taking one Black 3K capsules an hour before sex, you’ll achieve a great erection, you’ll perform better than ever before, you’ll last longer than you thought possible, and you’ll reach an explosive orgasm in the end.

Those, of course, are the claims, so lets take a closer look at the ingredients to see if they hold water.

Black 3K ReviewBlack 3K Ingredients and How They Work

There is no specific product web page for Black 3K, but you can find information on the formula listed on some of the websites that sell it.

The full ingredients list includes:

Goji Extract, Deng Sen Extract, Atractylodes, Cinnamon Bark, Dismutase, Cornus, Cuscuta, Dang Gui, Licorice, Condonopsis, Cordyseps Sinensis, Rubus, Panax Ginseng, Pueraria lobata, Superoxide, and Dismutase.

Most of these are not the usual suspects when it comes to enhancement ingredients.

Sure there’s Goji which is meant to increase virility, Ginseng for energy and stamina, and Cordyceps for libido, but most of the others are pretty unfamiliar.

The label warns that you need to consult your doctor if you have a heart condition or experience any side effects. There’s actually another product that’s come out recently called Black 4K, which by all accounts is virtually the same thing as Black 3K.

Black 3K Pros and Cons

Advantages of Black 3K

  • You don’t have to take it every day.

    There’s no commitment necessary.
  • It’s not expensive to try.
  • The few Black 3K reviews we’ve found have been very favorable, saying it really helps erections.

Disadvantages of Black 3K

  • The ingredients are mostly unfamiliar.
  • The warnings about heart problems may raise suspicions that there may be some undisclosed ingredients in the formula that will cause problems for anyone taking medications for a heart condition.

Where to Buy

You can purchase Black 3Konline at Amazon among other retail sites.

I’ve seen prices from $8.99 to $12.99 so make sure you shop around.

Update (5/19/2018) – Black 3K contains hidden ingredient!

So I was taking a brief look through this post, seeing if there was any info I could add since I last took a look into it.

It turns out that the FDA issued a public notification on Black 3K back in December of 2016, recalling the product from the market.

Why did they do that?

Well, an FDA lab analysis confirmed that Black 3K contains Sildenafil, which happens to be the active ingredient in Viagra.

This is not the first time this has happened.

In fact, in the last year alone the FDA has recalled literally DOZENS of tainted sexual enhancement products, including:


It happens all the time that fast acting male enhancements get recalled when the FDA discovers they use undisclosed ingredients, potentially dangerous for people with heart conditions and those taking medications for them.This hasn’t been the case with Black 3K, but the formula looks like the same kind of formula usually found in these products.

The reviews for Black 3K are very favorable.

Just proceed with caution if you’re going to use it.

Black 3k pill review

By Frank,  Dec 21, 2015

It took almost 6 hours before it started working for me but once it kicked in it worked for 3-4 days for me which was awesome. Thumbs up (or should I say something else was up) for this product.

I bought 1 pill for $10 from an adult store and was not disappointed. The owner said it was the last one and could not keep them in stock more than 3 days.


An hour after ingestion, I began to get minor head rushes but no headache, increased heart rate and increased energy. No automatic erections, but libido is ready to go.


The slightest encouragement from your partner provides immediate response with increased proportions and lasts as long as you are still interested. The single pill was good for 2 days, before another was required.


Goodbye Cialis.

I found it very helpful

By Lorenzo,  Apr 6, 2015

When I bought the capsule, the guy behind the counter told me that I could open the capsule and divide the dosage in half if I was afraid of it being too strong. I did that and both half dosages worked well for me, making me harder and giving me more endurance than I had expected.


I did have a slight headache when I used the second half dose. I plan on buying another tablet and splitting it into three parts to see how that works.

I’ve used Black 3K twice and was VERY happy with the results. I did experience a slight headache and some sleeplessness, but nothing different than my experiences with Viagra.


I felt larger, my erection was harder, and I lasted much longer than usual. Quite honestly, I felt I could have gone even longer, but was in complete control of the timing of my release.


It does say on the package to only use one dose within a 60-hour period. My second dose was slightly earlier than 60 hours, but I noticed no adverse effects.


I look forward to trying it again.

Will any male enhancement pill make you fail a jobs drug test? -Zack

Generally, they won't. But I can't vouch for all of them. In fact, there are plenty that sneak undisclosed ingredients into their formula, and when that happens, it's completely impossible to tell.- Rob

Can I divide the capsule in half? Will this affect my heart condition??? -Ellis

I would not recommend this for anyone with a heart condition. Rhino products often contain undisclosed prescription ingredients - namely the active ingredient in Viagra, which may interfere dangerously with a heart condition and/or heart medication.- Rob
