Sometimes a product’s popularity can fool us. When we see that something has sold “millions of bottles,” we may think to ourselves that only a product that works can sell so well. Unfortunately, that’s not always the case.
When someone brought up to me that Prime Test, made by Prime Labs, was one of the best-selling T-Boosters on the market, I expected to find an air-tight formula with scientifically backed doses. Instead, I found a label with no transparency, and several highly questionable ingredients. So let’s dig in and see how Prime Test stacks up to the evidence, and whether their sales are all hot air.
Prime Test
Overall Rating: 3.5/5
Who is Prime Labs?
Prime Labs has founded their company on the premise that their products are founded in science. They even have a tab right at the top of their website proudly proclaiming “The Science.” Problem is, there’s no scientific study or proof cited on this page. They don’t offer much in the way of who they are or what they stand for outside of helping men live their “optimal life,” and offering “vitality-boosting supplements.”
I notice that they don’t actually use the word “Testosterone” on any page of their website. That is to say they don’t actually claim to boost your hormone levels, a telling omission that seems to indicate they know their product doesn’t increase Testosterone.
Pros & Cons
Pros
Cons
Best Alternatives
If you’ve read enough about Prime Test, and want to move on right away to something formulated with quality ingredients proven to increase Testosterone, I don’t blame you. Here are the tried-and-true supplements we’ve extensively researched.
TestoPrime
Overall Rating: 5/5
One of the few supplements we’ve ever reviewed to get a 5 out of 5 rating, TestoPrime has 12 ingredients scientifically proven to help build Testosterone. It can not only help you generate more total-T, but also retain Free Testosterone so you can build muscle and stay lean.
Testo-Max
Overall Rating: 4.7/5
For the people who are looking for fast results in the gym, Testo-Max is the no-frills, muscle-gaining, fat-burning T-Booster many athletes are looking for.
Prime Male
Overall Rating: 4.5/5
A well-rounded T-Booster with proven aromatase-blockers, so that you can keep all the Testosterone you produce. Perhaps the best version for people new to T-Boosters.
Claims of Prime Test
It’s difficult to say exactly what Prime Test claims it will do for you, or anyone else for that matter. They use language like “optimize performance” without saying what that means. Is it more lean muscle? Better sexual function? Longer stamina during workouts? Hard to say. Especially when they say their ingredients are “associated” with “male performance.
This is typically where I would give you a breakdown of claims, but really Prime Test doesn’t make any. They say their product is “the perfect pairing to a workout or a night out,” but they don’t say why. I suppose that protects them from any accusations of false advertising, because their formula appears to be largely absent any effective ingredients. And what good ingredients they do have we can’t see the doses of. It’s entirely possible there are as little as a few milligrams of anything.
Ingredients
At least we have a dose for this ingredient. And there is a tenuous link between athletes with high calcium and higher T-levels. But the issue here is relativity. Put another way, a glass of milk has 283 mg of Calcium. Do you need a supplement to get what a couple glasses of milk or yogurt gives you?
Horny Goat weed
I’ve almost worn out my keyboard dispelling myths about T-production, and one of those myths is Horny Goat Weed. I’ve even found one study where it lowered T in lab animals. The one study we’ve found with some evidence used 50 to 200 mg per kg of body weight. Quick maths for you, that’s over 4,000 mg for a 180 lb. man. Way more than in this product. No secret then why top-rated product slike TestoPrime don’t include it in their formulas.
Tongkat Ali
This is another of the possibly effective herbs in Prime Test. Tongkat Ali can raise T-Levels. Two problems: we again don’t know how much is really in this Prime Test, and Tongkat cannot be sold in some European countries because of possible safety concerns. Two good reasons we don’t see it in our top T-Boosters.
Saw Palmetto
Results on Saw Palmetto have been mixed. In some studies, it helps, but in some studies Testosterone actually goes down with Palmetto use. Yet again, something we don’t see in our Top male supplements.
Orchic Substance
The biggest head scratcher of them all. First of all, I don’t like anything called a “substance” on my supplement label. Second, I don’t like that this one specifically is bull testicles. I have nothing against anyone’s dietary choices. I myself like to try exotic foods. But I firmly believe in transparency. And putting bovine glands in a supplement and not calling it that goes foul for me. Especially as there’s no proof that bull testicles do anything for male performance, testosterone, or anything else.
Wild Yam Root
I have hunted an scoured the databases for something about Wild Yam and testosterone. I’ve found two studies. One saw a rise in T-Production following a highly specific preparation, rats did indeed have more Testosterone; but this experiment was conducted on rats with intentionally damaged testes, which may not have a lot of bearing on normal healthy humans.
Sarsaparilla Root
Here we need to pay a bit of attention to the scientific name of the plant used. Prime Labs says they use Smilax galbra, which is used traditionally as an aphrodisiac. Some studies of Smilax calophylla have been studied for Testosterone effect. But no clinical trials I could find had done any work on this particular Sarsaparilla Root benefiting male health.
Nettle Root
With the next three ingredients, Prime Test finds itself back on good scientific footing. I’ve written previously about Nettle Leaf, and there is some of the same benefit to the Root of the plant to help prevent aromatase.
Boron
This essential mineral not only helps us break up Testosterone from binding into sex-hormone binding globulin, but it also helps us retain and use Vitamin D more effectively for our hormone health.
Magnesium
Here I’m giving Prime Test credit for something they may have done by accident. Magnesium isn’t even listed as an “active” ingredient on their label, even though Magnesium has demonstrated T-Boosting benefits in aging men.
Should You Try Prime Test
Prime Test seems geared toward people who want an aphrodisiac benefit rather than a true Testosterone boost. They don’t have ingredients like D-Asp or Ashwagandha that are in proven supplements like TestoPrime, and what they do include has questionable evidence, or no evidence, supporting it.
Top Alternatives
Final Verdict
In the end I think my responsibility as a fitness and health writer impels me to advise you to seek a male supplement elsewhere. It would take a large body of clinical evidence for me to support putting bull testicle extract into a supplement, not listing it clearly on a label, and selling it. Especially when there are so many other proven, transparent formulas on the market.
