Prime Labs – Prime Test Testosterone Booster Review

A viable option for a health boost?

Prime Labs is a distributor of dietary supplements derived from herbal ingredients/superfoods which may support overall health and well-being.

And their testosterone booster is sure to draw a lot of curiosity and skepticism from those interested in finding natural ways to boost their own levels.

But in a world where testosterone and sex drive are dipping to unhealthy levels more than ever; it’s no wonder many individuals are seeking alternative options.

Prime Test is one of the top choices on the market and we wanted to do a review to see what it was all about…

Note: Testosterone boosters are by no means a substitute for testosterone replacement therapy. And they should not be used as a treatment for any condition.

Test Booster Benefits

Let’s discuss the active ingredients in the Prime Test formula to determine the potential benefits of each…

Note: The following ingredients are generally considered safe for consumption.

But you should always consult with your doctor before use if taking any medications or if you suffer from any health conditions.

Horny Goat Weed

Horny Goat Weed is an herbal supplement typically used to improve erectile dysfunction (ED) which affects nearly 30 million men in the United States. (1)

And the active ingredient in Horny Goat Weed is icariin which is the extract of a Epimedium plant.

Now, although there’s limited evidence for the positive effects of Horny Goat Weed on ED, one study showed a significant improvement in nerve-injured rats. (2)

But this is promising evidence for human use.

Tongkat Ali Extract

Tongkat Ali (Eurycoma longifolia) is another promising medicinal herb but with more evidence for its efficacy from several studies.

One study tested the potential positive effects of Tongkat Ali for stress and psychological mood in 63 (32 men and 31 women) moderately-stressed subjects subjects for 4 weeks. (3)

And by the end of those 4 weeks, the study found that daily supplementation of Tongkat Ali does, in fact, have promise for stress reduction.

The study noted that it may be an effective approach to staving off detrimental effects of chronic modern stress as it relates to common lifestyle factors (diet, sleep deprivation, exercise, etc).

Another study took 25 (13 men and 12 women) senior-aged (57-72 yrs) volunteers and gave them 400-mg of TA extract daily for 5 weeks. (4)

And there was a significant increase in total and free testosterone in both genders, with equal improvements in muscular force.

This is great news for individuals in this age range who desire to elicit an improvement in performance. But for stress and mood, Tongkat Ali seems to be a viable option for anyone.

Although, results may vary and are not typical for everyone, especially to the same extent.

Saw Palmetto

Saw Palmetto extract is used in Europe and the United States to potentially treat and/or improve the symptoms and health conditions relating to the prostate, decreased sex drive, and other conditions.

But evidence is lacking for the potential effects of Saw Palmetto in improving any health condition, even relating to the prostate; which it’s primarily used for. (5, 6)

Orchic Substance Wild Yam Extract

Wild Yam extract is another ingredient with little evidence to support any positive effects it may have on the human body.

One study found that it has no effects on menopausal symptoms in women. And it seems according to related information that wild yam is no better than a placebo. (7)


Sarsaparilla may have anti-cancer properties according to one study. And in another, it was found to dramatically improve psoriasis. But it’s also known to have anti-inflammatory, and anti-bacterial properties. (8, 9)

Nettle Extract

Nettle extract shows some promise for prostate health, male pattern baldness, and restorative benefits. It also has diuretic and possibly anti-inflammatory effects as well. Plus, it’s rich in zinc, iron, and chloropyll.  (10)


Boron (in chelated form) offers several benefits which includes improving magnesium metabolism, calcium, phosphorous to prevent excessive loss of these nutrients through urine. (10)

And it’s also necessary for the prevention of rapid hormone breakdown in the body.

How Much Should I Take?

If you’re new to supplementing with herbal substances, always start with the lowest dose first for a few weeks to see how your body may respond to the ingredients.

But if you’ve taken your daily doses for at least a few weeks with no effects, you can try the higher serving recommendation. However, you should keep in mind that natural, plant-based ingredients take longer to feel the effects.

And even if the main ingredients are derived from plant sources, they can still cause side effects which is something to keep in mind.

Best Time To Take a Test Booster

As long as you’re taking the caplets daily at the same time, it really doesn’t matter. Take them in the morning, afternoon, or evening, the results will not differ.

But, of course, you can never go wrong with following the directions on the product label.

Prime Test directions are to take 2 caplets once or twice daily.

Why Prime Test?

Prime Test contains all-natural, active ingredients and the product is made in an FDA-registered facility. It’s also a USA-made product which is thoroughly tested for quality.

And many of the ingredients are promising for potential health benefits relating to slight elevations in testosterone and sex drive. Plus, you may get the positive effects on mood as well.

However, certain ingredients may not have any effects at all.


While there are several potentially beneficial ingredients in the formula, a proprietary blend is often frowned upon due to the lack of full transparency for the ingredients amounts contained in the product.

Proprietary blends are sort of a workaround for not having to disclose the full amounts of all the ingredients included.

Also, fillers and additives are often used to make up a portion of each serving and with a proprietary blend, it’s hard to know exactly how much of the beneficial ingredients you’re actually getting.

And a few of the ingredients like Horny Goat Weed, Saw Palmetto, and Wild Yam may not even have any beneficial effects.

But even if a product like a testosterone booster has positive user feedback, the only way to know for sure exactly how effective a product is, would be to give it a run.

How Much Does It Cost?

A bottle costs $20 for 30 servings (2 caplets per serving).

A once-daily serving will last you 30 days, and a twice-daily serving will last you 15 days. And at a $20 price point, it’s reasonably-priced, although we’re not exactly sure how much of each ingredient is contained in the product.

Final Thoughts

Prime Labs – Prime Test Testosterone booster is one of the more popular supplements which may help to give you a slight boost in testosterone, along with additional health benefits as well.

You likely won’t see a huge change in performance or health but that’s typically expected with dietary “supplementation”.

However, natural substances do take at least a week or more for the potential effects to be evident.

So, take Prime Test for what it is… a possibly beneficial addition to your health regime.

T-levels are an important aspect for any bodybuilder to keep in check. If you’re looking for alternative ways to boost your testosterone naturally, you can check out our official top 5 guide right here.
