Cialix is a male enhancement supplement for testosterone and libido support. The brand previously claimed its supplement could also increase penis size, but appears to have removed those claims from their website at the time of updating this article.
But does Cialix contain ingredients proven in clinical studies to be effective for increasing testosterone and sex drive? Is it possible for an oral supplement to increase penis size? And does Cialix cause side effects?
In this article we'll answer all of these questions and more, as we analyze the ingredients in Cialix to give our take on whether or not the supplement is likely to be effective, and whether or not it's healthy.
We'll explain whether or not a dietary supplement can really increase penis size, give our take on whether Cialix is likely to cause side effects, and share our concerns about the brand generally.
Key takeaways:
- We consider most active ingredients likely underdosed
- Contains one potentially effective active ingredient for boosting T
- We do not currently recommend Cialix
Ingredient Analysis
The active ingredients in Cialix are shown below:

The supplement contains a proprietary (prop) blend with a total dosage of 500 milligrams (mg), which equates to an average ingredient dose of 29 mg.
As we explained in our review of Alpha Brain ingredients, prop blends only publish the total dose rather than the individual dose of each ingredient, which makes it challenging to assess the safety and efficacy of a supplement.
Eurycoma longfolia was shown in a 2017 medical review to improve symptoms of erectile dysfunction (ED).
Saw palmetto extract was shown in a clinical trial published in the Urology journal to improve erectile function in animals.
Bovine orchic susbtance is derived from the testicles of cows.
Boron is the only ingredient in this formulation we consider potentially effective, since it's been clinically shown to support testosterone (T) increases at a lower dose than the average ingredient dose in Cialix.
The good news about this supplement is its inactive ingredients, shown below, should be safe and non-toxic:

Overall, we consider Cialix potentially effective for improving T levels in men.
However, we can't confirm this because of the prop blend.
Can Supplements Increase Penis Size?
Upon our initial publication of this article, the Cialix website suggested that the supplement could increase penis size.
The brand failed to cite any research or provide any proof of this claim, and we haven't come across any clinical studies suggesting that oral supplements can permanently increase penis size. The brand has since removed these claims.
As we explained in our VigorNow review article on another supplement for penis size, it seems logically impossible for an oral supplement to alter the length and girth of the penis.
The penis is an appendage, just like the fingers. There is no biological mechanism for its permanent growth beyond puberty.
Some supplements can increase erection size by improving blood flow or arousal, but only to a maximum determined by the existing size of the penis.
Does Cialix Cause Side Effects?
Cialix doesn't appear to have been studied in any clinical trials, so it's challenging to say for certain whether or not the supplement is likely to cause side effects.
However, we can make an educated guess based on its ingredients.
The active ingredients in Cialix are mostly safe and well-studied, however, the fact that the brand fails to publish the individual ingredient dosage increases the risk of side effects in our opinion.
Side effect risk is intractably tied to dosage.
An active ingredient may not cause side effects at a dose of 200 mg, but it may cause side effects at a 400 mg dose.
Without knowing the individual ingredient doses, we can't establish whether or not those doses are within a safe range.
For this reason, we generally recommend avoiding supplements containing prop blends that aren't studied in clinical trials, because it's very challenging to assess their safety or risk of side effects.
