Testadrox: An Evidence-Based Review

Testadrox is a natural testosterone boosting supplement by the makers of Megadrox which is supposed to build muscle and improve sexual wellbeing/function.  It contains very similar ingredients to many other natural test-boosters we’ve seen…


If you read our review of Megadrox, you know that we were unable to obtain a valid Supplement Facts panel for it and it seemed like the manufacturer was going out of their way to make sure it wasn’t obtainable.  We’re thrilled to see that isn’t the case with Testadrox, as the above supplement facts panel was pulled directly from the Testadrox site.

Testadrox Ingredients

Testadrox contains 8 active ingredients, all of which can be found in various other “natural test-boosting” supplements.  The individual doses are concealed within the FlowViv Max-Test Blend, but we can assume, based on an overall weight of 1484mg, that most of the ingredients are probably under-dosed.

Horny Goat Weed

Horny Goat Weed is generally standardized for the active component Icariin which is believed to underlie the erectogenic properties of the herb itself.  Icariin has been shown to improve erectile dysfunction by inhibiting phosphodiesterase type 5 (PDE5), the same basic mechanism of action as many other erectile-aids out there.

Unfortunately, there is no evidence to suggest that Horny Goat Weed can increase Testosterone in humans, but Icariin has demonstrated Testosterone mimicking properties in mice.  More research is needed to understand it’s effects on Testosterone, but as an erectile-aid, it’s effective.

It’s possible that Testadrox contains an effective dose, but we can’t be sure (because of the proprietary blend).

Tongkat Ali

Tongkat Ali, also known as Longjack, has been used in traditional medicine as an aphrodisiac and sexual dysfunction-aid.  Research indicates it can help restore Testosterone in men with abnormally low levels, but it’s never been shown to “boost” Test levels beyond the normal range.

In the context of Testadrox, Tongkat Ali may increase libido and provide the illusion of increased Testosterone, but it can’t actaully increase Testosterone (unless you have abnormally low Test levels already).

Saw Palmetto

Saw Palmetto is commonly used as a treatment for Benign Prostatic Hyperplasia (BPH) because it suppresses conversion of Testosterone into DHT (a cause of BPH).  If you’re looking to raise free Testosterone levels, this is a good thing because the less Testosterone that gets converted to DHT, the more free Testosterone remains.

However, studies in healthy human subjects are non-existent so it’s not clear whether Saw Palmetto really increases free Test levels under normal conditions.  In the context of Testadrox, it’s a pretty speculative ingredients.

Orchic Substance

Orchic Substance is obtained from Cattle testicles and is supposed to promote healthy testiculur function in humans.  However, there is absolutely no evidence to support this claim.  No study has shown that substances obtained from animal testicles can somehow improve testicular function in human males, and honestly, it sound ridiculous when you think about it.

It would appear as though the makers of Testadrox are just reaching here.  Trying to use an ingredient that sounds effective, but probably isn’t.

Wild Yam

Wild Yam appears in a lot of natural test-boosters because of preliminary evidence that suggests it may help control Estrogen.  Most of the studies are involving cancer, where high Estrogen leads to the spread of cancer cells, so it’s not clear how Wild Yam effects healthy males.

For now, we’d still consider it pretty speculative.  In the context of Testadrox, it probably isn’t very useful.


Like Wild Yam, Sarsparilla appears to possess some anti-estrogenic activity, but no studies have been conducted in human males, just cancer patients.

Nettle Extract

Resaerch indicates that Nettle Extract may reduce the binding of DHT to Sex Hormone Binding Globulin which may indirectly increase free Testosterone levels.  However, there is not much research to go on, especially in healthy human subjects.


Boron is a mineral that you may have come across in multi-vitamins or mineral supplements before.  It fulfills a wide variety of functions in the human body but research also indicates it may be able to boost Testosterone levels to some degree, but not to a particularly significant degree. It’s worth noting that Boron supplementation has also failed to influence Testosterone parameters, so it can’t be considered reliable.

Testadrox Ingredient Takeaway

The ingredients in Testadrox are most ineffective for boosting Testosterone beyond the normal range or suppressing Estrogen below the normal range.  If you’re someone who suffers from abnormally low Testosterone levels already, you may benefit to some degree, but the same benefits could easily be obtained with other clinically dosed Testosterone Boosters.

Is Testadrox Safe?

Testadrox is entirely safe, assuming that the ingreidents listed on the label are really in the product and nothing else.

Fake Reviews

If you look around the internet for reviews of Testadrox, you’ll stumble across a bunch of websites that appear to be review sites but are actually set up by the company that makes Testadrox to funnel people to their main site to buy it.  Beware of review websites that claim to be fair and unbiased but then try to get you to click on some sort of “Free Trial” or “Limited Time Offer”.  These aren’t review sites, they’re just a scam.

The Bottom Line

Testadrox has what it takes to increase your libido and improve sexual function, but it won’t boost your Testosterone beyond the normal range and help you to build muscle.  If you want to actually put on pounds of lean muscle, check out our Best Muscle Builders List.  If you’re someone who suffers from abnormally low Testosterone levels, some of the ingredients in Testadrox might help you, but there are much better Test Booster formulas out there as well. exists to educate the supplement community and seperate the science from the hype.
