Size Up XL Review

By: Rob Miller
Fact Checked On: 6-19-2024

size up xlLet’s just open this review by admitting right away that we will NOT be recommending the Size Up XL product.

This is due to the simple fact that the manufacturer makes a great many claims about the effectiveness of this “enlargement product”, but offers absolutely no information about the product itself.

Our research provided us with a great deal of hyperbolic language about the “longer, thicker, and harder erections” a customer would acquire, and even that these would be permanent effects, but there was nothing to backup all of this hot air.

We decided to do a solid investigation of the product anyway, looked for customer feedback, and even checked out the price per dose to before making this decision.

How It Works and Ingredients

Size Up XL claims to use “a blend pharmaceutical grade ingredients,” that work in two phases, but they fail to indicate exactly what these ingredients are.

Upon reading the description of the processes described “drastically increasing the blood flow to the penis and stretching the walls of the Corpora Cavernosa” we can only guess at what the product contains.

We feel confident in saying that there are probably one or more of the best nitric oxide, or NO enhancers at work.

For instance, many bodybuilding formulas rely on NO to create vasodilators in the blood stream.

These dilate the blood vessels – allowing them to easily receive increased supplies of blood, nutrients, and oxygen. Body builders use this to get that engorged or bursting look in their veins and muscle tissue.

This exact same process is what occurs in the penis when it is introduced to NO and vasodilators.

The key compound used to create this effect is Arginine, and we assume that is what is at work in Size Up XL.

Over time the amount of engorgement in the penis is going to stretch out the walls and cells, and this will allow erections to get bigger for quite a while.

We can assume that Size Up XL uses this sort of technology, but it is ONLY AN ASSUMPTION because the manufacturer fails to reveal even a single ingredient.

The fact that the manufacturers also claim that this product handles problems with PE (premature ejaculation) left us scratching our heads because enlarging the penis has nothing, scientifically, to do with the underlying causes of PE.

Customer Reviews

There are a few reviews on Amazon that suggest that the product may work, but the validity of these reviews of size up xl are called into question. There are no documented results in the form of picture proof or doctor testimonials, something that should be necessary when making claims such as these.

Furthermore, some reviews have actually questioned whether the feedback has actually been placed by company personnel. Naturally, we were surprised to see a money back guarantee, but then the “contact seller for full details” made it clear that this guarantee had absolutely nothing to do with the manufacturer.

Where To Buy

Buying the Size Up XL product is more than a simple leap of faith because the literature available does not explain how many pills are contained in each bottle.

Instead, the consumer is told only that it is going to take four to six bottles to get the best results. The prices ranged between the standard retail value of $70 to the price of $40 for a single bottle.


We do not recommend the Size Up XL product.Its claims have no clinical evidence and there is no list of ingredients provided, no quality assurances, and no way to easily get your money back if the product is not satisfactory.

We know that there are a lot of people looking for a quick fix for a small penis, and that a product that uses such bold and aggressive language in its official descriptions as Size Up XL does might be convincing, but customers would be far better off doing a bit more searching because this product is just too vague to be trustworthy.

If there was more information readily available, then maybe I would not be so apprehensive to give Size Up XL a glowing recommendation, but the fact is that I am not going to get in the corner of a product that doesn’t have a lot out there on it when there are store shelves and websites that are stocked to the brim with similar supplements that have a whole lot of information that you can easily access without having to dig around like you’re Indiana Jones.

    1. Hey Kina,

      Unfortunately, I’ve yet to find a permanent enlargement pill. The closest thing I’ve tested that works well for temporary enlargement is Vigrx Plus, which you can read about in my review here:

      However, the gains are not permanent. You need to either use it continually, or use an extender device called the Phallosan Forte or a water based pump called the Bathmate.

      Check out my reviews of each below:

      Phallosan Forte –

      Bathmate –

      Hope this helps and let me know if you have any other questions.
  1. I’ve had great results from this product so far. I’ve been able to gain nearly 1.5 inches in length and 1.2 inches in girth in the 4 months I’ve been taking it. That may not sound like much but going from 5.5″ to 7″ is a big difference. I’m hoping to get to 8″ eventually, that would be awesome.

    I also noticed that since taking this I have some more stamina too though I don’t know if this product had anything to do with that.
  2. It worked for me and am pretty satisfied with the results. At start I was unsure about the ingredients but I have to say it has given me nothing except a good erection whenever I need it.
