Fact Checked On: 12-20-2016

Probolan 50 is a new bodybuilding supplement coming out of Poland that promises to replace all the stacks you used to need with just one product.

By taking Probolan 50, you’ll put on maximum muscle mass, and your results will start to be visible in as little as 48 hours.

They claim that until recently, it was only available to a select group of elite athletes, but now anyone can experience the benefits of results in 48 hours.

In just 48 hours, your testosterone will be boosted by 400%, you’ll see visible growth in muscle mass, you’ll feel an increase in strength and motivation, and your fat will be converted to pure muscle.

Those are pretty huge promises, so we’ll have to look into the Probolan 50 formula to see if it can deliver.

Probolan 50 ReviewProbolan 50 Ingredients and How They Work

The official Probolan 50 website has a very complete FAQ section, with one very important piece of the puzzle missing.

The piece that’s missing is the formula.

There is almost no information about the ingredients used to get you to these amazing results.

A few hints are provided:

They say that it blocks conversion of testosterone to DHT.

They say that only organic ingredients are used in the formula and there are no harmful or illegal substances.

They say it contains an estrogen blocker and inhibits the action of Sex Hormone Binding Globulin (SHBG).

But that’s as specific as Probolan 50gets for most of its ingredients.

The one named substance is Epihydroxetiolan-17-Ester Matrix which is said to be “made from” the unique blend in Probolan 50. This matrix is what drives the 400% increase in testosterone levels.

I did a little research on Epihydroxetiolan-17-Ester, and there really isn’t a ton of information on it apart from some vague mentions in other Probolan 50 reviews.

There’s no Wiki page describing the compound, nor will you find any info on it in’s forum, WebMD, or

According to their official website, there was a clinical study conducted by a Dr. Steven Price, who we’re guessing is the renowned gastroenterologist who practices in Miami, FL.

Probolan 50 provides excerpts of his report on their website, showing that he was very surprised at how effective Probolan 50 turned out to be.

Here’s an excerpt from his report:

However, they don’t link to the studies themselves.

This is very concerning.

While they may be showing you the positive aspects of this trial, they may be hiding some of the negative aspects of his report, including details on potential side effects with Probolan 50.

How To Use It

The recommended dosing depends on how long of a cycle you intend to use.

If you’re just using it for a month, during the first week, take 1 capsule daily, during the second week, take 2 capsules daily, during the 3rd week take 3 capsules daily, during the 4th week, take 2 capsules daily, during the 5th week take 1 capsule daily.

This protocol changes if you’re using a longer cycle.

Customer Reviews

There’s plenty of Probolan 50 reviews from customers who appear to have used it. However, most of those reviews are in other languages like Polish, Spanish, and Italian, none of which I speak.

There was one youtube video review that actually had english subtitles, and the reviewer noted very positive results with Probolan 50. Check it out below:

Right around the 1:20 mark he makes a claim that can’t be substantiated, and that’s “It helps transform fat into muscles”.

This is physiologically impossible to do.

The fact that he says this leads me to believe that he either:

a. Has no idea what he’s talking about, or

b. Is nothing more than a shill, ie someone just trying to pitch the product to you.

Looking deeper into the Youtube reviews you’ll find this relatively useless unboxing of Probolan 50.

I never understood why people post vids like this. Maybe they’re thinking people want to see if it’s shipped discreetly or something?

I don’t know, but I wouldn’t waste your time watching the whole thing.

Lastly, I found this video review, which luckily is in English.

Basically he mentions that he got a sample pack of Probolan 50 from one of his friends, and wasn’t expecting much. He says he noticed big results after just 2 days of using it, including increased mental focus in the gym, as well as visible fat reduction.

This of course correlates with their claims, but he doesn’t put a before and after picture of his results with Probolan 50, so we can only take his word for it.

Pros and Cons


  • The ingredients are said to be all natural.
  • There’s a money back guarantee.


  • They don’t provide an ingredients list.
  • Shipping costs $25.
  • They promise that you’ll see visible results in just 48 hours.
  • They claim to offer an unconditional money back guarantee, but when you read more closely you see that it only applies to unopened packages.
  • There are independent Probolan 50 reviews posted on Youtube, but many are in languages other than English.

Where to Buy

You can only purchase Probolan 50 through the official website, It seems like they ship to virtually every country, including the UK, Australia, Canada, and the US.

However, with no list of ingredients there’s no way we can tell if it would be banned in certain countries.

A one month supply costs $49 plus $25 for shipping.A 10 week cycle goes for $98, and the 16 week cycle sells for $147. There’s a 90-day money back guarantee, but it only applies to unopened packages, meaning that there really is no way to try it and still get your money back if it doesn’t work.

probolan 50 money back guarantee

I checked around with my local retailers and it doesn’t appear that they sell Probolan 50 in stores like GNC, Vitamin Shoppe, Walgreens, CVS, or Walmart.

However, I did see it for sale on ebay for about $33, which is significantly cheaper than buying it on their official website.


Probolan 50 looks like all hype and very little help to me.

A supplement that wants to be judged on its actual merits won’t make ridiculous claims like “permanent muscle growth” and they’ll tell you what’s in it.

They also won’t try to tell you there’s a money back guarantee, then refuse to accept the return after you’ve tried it.

I see no reason at all to recommend Probolan 50.
