About Invigorate RX
Invigorate RX is a male enhancement dietary supplement that promises to help boost blood flow to the penis and expand penile chambers, leading to bigger, longer lasting erections.
Specifically, the website tells us this dual action formula of herbal extracts and active botanicals stimulates nitric oxide and free testosterone production. In turn, this also leads to longer stamina and staying power, stronger performance, a surge in youthful energy, intensified orgasms, and increased sexual confidence.
Despite all of this, the website emphasizes that the supplement is completely safe to use and 100 percent free of side effects.
But will Invigorate RX deliver added inches, whether in length or girth? As a matter of fact, based on the available clinical evidence, can you expect it to deliver at all?
Here, we’ll briefly help you weave the facts together and come to an informed conclusion. We’ll start by unpacking the core concepts mentioned on the supplement’s website, which will come in handy later.
Your Quick Reference Guide to Erections
Achieving an Erection & Erectile Dysfunction
On the surface, the Cleveland Clinic reports that an erection is a fairly straightforward biological function; blood flows into two parallel chambers, called the corpora cavernosa, which are filled with a sponge-like tissue. As this occurs, the penis grows in length and girth sufficient enough to enable sexual penetration.
Then, once climax has been reached or the sexual stimulus ceases, the blood flows away from these chambers and the penis becomes flaccid.
However, the Mayo Clinic emphasizes that, “sexual arousal is a complex process that involves the brain, hormones, emotions, nerves, muscles, and blood vessels.” Consequently, erectile dysfunction—or the inability to achieve an erection sufficient enough for sexual intercourse—“can result from a problem with any of these.”
Common culprits include cardiovascular issues (e.g., heart disease, atherosclerosis, high cholesterol and blood pressure, etc.), diabetes, obesity, tobacco use and alcoholism, depression, excessive stress, and prostate treatments, to name just a few.
Next, let’s take a look at the nitric oxide and testosterone mentioned on the Invigorate RX website.
The Link Between Nitric Oxide, Testosterone, & Erections
According to registered dietitian and American Dietetic Association spokesperson Jim White, nitric oxide is a signaling molecule naturally produced in the body that, among other things, is responsible for controlling blood circulation.
This gas is created once the “enzymes in the body break down the amino acid, arginine,” commonly found in foods like spinach, sesame seeds, and shrimp. We’ll talk more about this in the ingredients section next.
Testosterone, on the other hand, is a hormone responsible for increasing hair growth, muscle size, and strength, which peaks during the late twenties and starts decreasing after the 40s. And while WebMD indicates this drop could decrease the size of a man’s flaccid penis, ChoosingWisely.org reports that it doesn’t seem to impact erectile function (or dysfunction, as the case may be).
Finally, outside of an increase in firmness as a result of boosted blood flow, and the slight increase in length/girth this might cause, Psychology Today’s Michael Castleman emphasizes that penis enlargement products don’t work, by and large.
Alright, now that we’ve covered the basics, let’s take what we’ve learned and apply it to Invigorate RX’s ingredients.
What Ingredients Does Invigorate RX Contain?
While no supplement facts label was listed on the Invigorate RX website at the time of our research (we called service for more details, who didn’t have any available), we’re told it contains the following:
- Muira Puama Extract
- Asian Red Ginger Extract
- Saw Palmetto Berry
- Ginkgo Biloba Extract
- Horny Goat Weed Extract
While we’re not medical professionals, according to their summaries of the available clinical evidence, sites like WebMD, the Natural Medicines Database, and Examine.com indicate that taking 5 grams of l-arginine per day may help improve sexual function in men with ED.
They emphasize that taking lower doses might not be effective, so we think it’s important to reemphasize that we’re not told how much Invigorate RX contains.
Outside of this, these same sites cumulatively indicate there’s insufficient clinical evidence the remainder of the supplement’s ingredients will deliver on the manufacturer’s claims.
With this said, there are two potentially supportive individual studies cited on the Invigorate RX website:
- A 16-week 2002 study conducted at the University of Ulsan College of Medicine, which found that 2,700mg of Korean red ginseng increased mean erectile function and tip rigidity
- An overview (not a published study) references three trials (one of which is above) indicating that ginseng shows promise for erection quality
Could Invigorate RX’s Ingredients Cause Side Effects?
Overall, these same sites indicate that most of these ingredients won’t cause anything worse than mild, temporary digestive upset (no specifics or dosages provided).
However, they also emphasize that l-arginine can have a moderate interaction with medications that lower blood pressure. Furthermore, in some individuals (again, no specifics provided), ginseng can lead to mild heartburn, diarrhea, and general stomach discomfort, while saw palmetto can cause mild dizziness, headache, nausea, vomiting, constipation, and diarrhea.
Finally, they indicate there isn’t enough known about muira puama to understand if it’s safe, or what the possible side effects might be.
How Much Does Invigorate RX Cost?
The only way to purchase Invigorate RX at the time of our research was through a 14-day trial for $6.96 S&H, for which you’ll receive a full 30-day supply (60 caplets).
Once the trial ends, you'll be charged the full price of $89.97. Then, you’ll be enrolled in monthly recurring shipments and billed $89.97 each time.
Outside of the trial, all unopened bottles of Invigorate RX come with a 30-day refund policy, less S&H and a $9.97 restocking fee. In order to request one, support can be reached at 888-465-4650 or Support@EliteMemberArea.com.
Pro tip: When we reached out to customer service earlier, we learned that Invigorate RX is supported by a third-party billing company, who don't have access to anything other than what's listed on the supplement's website. In other words, if your question doesn't revolve around billing, we were told they're probably not going to be able to help.
Do You Need a Testosterone Supplement Like Invigorate RX in the First Place?
A quick online search will reveal that there are perhaps thousands of testosterone and male enhancement supplements competing with Invigorate RX, with prices ranging anywhere from less than $20 to well over $100. In fact, the HighYa team has written about more than 70 of these products alone. What have we learned during all this research?
As we discuss in Do Testosterone Booster Supplements Work, sites like the Natural Medicines Database, Examine.com, and WebMD typically report that most of the ingredients these products commonly contain won’t impact testosterone levels—or, by proxy, erection size or quality.
Because of this, as well as the fact that low testosterone levels and frequent sexual performance problems can be difficult to handle, we’d recommend speaking with your physician before purchasing a supplement like Invigorate RX. They can run the appropriate tests and recommend science-backed options based on your diagnosis.
With this said, if they recommend you proceed with a dietary supplement, we’ve learned that you’ll only want to do business with companies that:
- Provide a clear list of ingredients, including dosages, with little-to-no proprietary blends
- Support their claims with double-blind, placebo-controlled, peer-reviewed clinical research
- Don’t automatically sign customers up for free trials and recurring shipments. And if they do, they should be very clear about what you’re agreeing to.
- Come with mostly positive online customer reviews
- Price their products more-or-less in line with the competition

Our Final Thoughts About Invigorate RX
Based on what we learned during our research, neither the individual ingredients nor the complete blend found in Invigorate RX has ever required a prescription, despite what's claimed on the supplement's website.
On top of this, sites like the Natural Medicines Database and WebMD report that, outside of l-arginine, there’s insufficient clinical evidence supporting the manufacturer’s claims for any of its ingredients.
And when it comes to l-arginine, we can’t be sure if it contains the same levels as supporting studies, since no dosages are listed on the website and customer support was unable to provide additional details.
Given these important details alone, we think you should speak with your doctor about whether or not Invigorate RX—or any other testosterone, male enhancement, or nitric oxide supplement, for that matter—will provide meaningful value based on your individual diagnosis.
