Pros and Cons

Ever since two former Harvard rowers got together and formed Force Factor in 2007, the company hasn’t stopped growing and evolving.

Their first product, the original Force Factor, was actually one of the first supplements I tested on Supplement Critique.

In fact, in the summer of 2008 I can remember Force Factor as being one of the most heavily talked about supplements on the market.

You can see why by this Google trends analysis.

In addition to several pre workout formulas, they make intra-workout powders, fat burners like LeanFire XT, post workout recovery products, daily nutrition, and a number of natural testosterone boosters.

We’ve tested and reviewed several, including:

test x180 vs Ignite and Alpha
^ I’ve tested ALL of them

All of these testosterone boosters use an ingredient called Testofen as the primary testosterone boosting component.

What is Testofen?

Manufactured by a company called Gencor, Testofen is a proprietary form of Fenugreek that is standardized for at least 50% Fenusides (furostanol saponins).

Some manufacturer sponsored studies have shown that it improves erectile function and libido.

Additionally, other independent studies show that Testofen had significant impacts on both upper AND lower body strength, and had no side effects.

effects of testofen on body strength and composition

It remains a popular ingredient in many testosterone boosters for it’s ability to mimic an increase in testosterone levels.

It’s been shown to improve muscle and erection strength, but evidence that it actually increases testosterone remains questionable.

What is Alpha King Testosterone Booster?

alpha king testosterone review

With Alpha King Testosterone Booster, Force Factor introduced a new and improved primary ingredient called AlphaFen.

This is also a proprietary form of Fenugreek, but it is more bio-available than Testofen.

So what’s the advantage of this?

One of the main advantages of this is that each pill can use less of the ingredient and still get the same results.

Instead of the commonly used doses of 2 capsules per day, with Alpha King you’ll only need to take 1.

Additionally, Alphafen is said to be superior in its ability to improve both sexual performance and muscle composition.

Who makes Alphafen?

The name has recently been trademarked by a company called SpecNova.

They are a Florida-based reseller and distributor of chemical ingredients used in nutritional supplements.

It’s been stated that clinical trials of Alphafen are currently underway, though I have been unable to confirm this.

Alpha King Testosterone Booster Ingredients

To get you familiar with the product, here’s a snapshot of the Alpha King Testosterone label:

alpha king testosterone ingredients label

With Alphafen at the helm, the Alpha King Testosterone Booster formula is rounded out with several other ingredients, including:

Black Maca Root

This herbal remedy is a powerful herbal aphrodisiac used for centuries in its native Peru.

Maca is also known to build stamina, boost athletic performance, improve mood and focus, and support bone strength and density. (Source)

Alpha King contains 100 mg of Black Maca Root.

Tribulus Terrestris

Tribulus is one of the most commonly used ingredients in testosterone boosters, and even in some male enhancement pills like Viril X and Virectin.tribulus terrestris benefits infographic
The science behind it remains inconclusive, but it is believed to boost total testosterone levels by increasing the amount of testosterone your body produces in the first place.

The theory is that Tribulus signals the pituitary gland to release Luteinizing Hormone, which in turn signals the testes to produce and release an increased amount of testosterone. (Source)

^ How Tribulus Terrestris Works

Over the years, this has been challenged by various researchers as a myth.

As a result, the notion that it actual increases serum testosterone (and doesn’t just mimic it) has become less and less accepted.

does tribulus help increase testosteroneThe debate now is whether it actually matters.

If you’re getting the benefits of a testosterone boost from Alpha King pills, what’s the difference?

Diindolylmethane (DIM)

A metabolite of a substance naturally found in cruciferous vegetables such as broccoli and cauliflower, DIM serves to balance male and female hormones in the body. (Source)

As such, it’s known to reduce the risk of hormone-driven cancers, such as prostate and breast cancers.

what does dim doThe way it works is by inhibiting the conversion of testosterone to estrogen, thereby increasing testosterone levels. (Source)

A secondary effect of this action is a reduction in Sex Hormone Binding Globulin (SHBG).

SHBG attaches itself to testosterone molecules, rendering them useless.

Increased estrogen in turn increases SHBG, so by inhibiting conversion of testosterone to estrogen, DIM prevents some of the activity of SHBG.

Most of the Test X180 formulas contain some additional nutrients aimed at improving energy and/or overall health.

This is NOT the case with Alpha King.

Another question is whether or not Alphafen will become the anchor ingredient for a whole new line of testosterone boosting products from Force Factor.

We’ll have to wait and see about this one as well.

Alpha King Side Effects

As with any supplement, adverse reactions are always possible.

Some of the more common side effects associated with one of the ingredients in Alpha King testosterone, specifically Tribulus Terrestris, include:

  • Difficulty sleeping
  • Tachycardia
  • Restlessness
  • Increased libido Source: WebMD

My Personal Alpha King Results

I finally got a chance to try out Alpha King, and I have to say I’m pretty impressed.

I only had a 2 weeks supply, but I could definitely tell it was working after just a few days.

The biggest effects I noticed were:

  • Enhanced libido
  • Increased energy
  • Improved mood
  • Improved athletic performance

The improved athletic performance aspect was actually more noticeable than one may think.

For me, it seemed like I was sleeping WAY better when taking Alpha King, which of course can make a big difference in how your performance is affected overall.

I didn’t notice any kind of effects on lean muscle mass, but then again, I only used it for 2 weeks, so that’s to be expected.

My guess is, if I were on it for a longer period of time (think 6 – 8 weeks), there would have been some improvement in this area.

Other Alpha King Testosterone Booster Reviews

When we originally wrote this article, there weren’t any reviews of Alpha King posted online.

Average rating of 3.8 / 5 stars on

Since then, a number of them have sprouted up on the GNC official website and Amazon.

On GNC, the reviews are fairly favorable, albeit mixed.

For example, one reviewer stated that he was thoroughly impressed by the supplement, noting that he could tell the difference in his stamina and workout endurance.

On the other end of the review spectrum, one reviewer stated that he was severely disappointed with his lack of results.

To add in some even more confusing feedback, one final testimonial noted that he’d only been taking the supplement for about 2 weeks and had nothing to report.

It should be noted that there were only 2 Alpha King reviews posted on Amazon, which is hardly a good sample testing size.

Alpha King Vs. Other Force Factor Products

As mentioned in the beginning of this review, Force Factor has a wide range of other testosterone boosting supplements in their product line. I’ve personally used almost all of them, and can attest to their effectiveness.

Where to Buy Alpha King Testosterone Booster

Along with many of the other Force Factor product line, you can find Alpha King at both GNC and Amazon.

Categorized as a “hardcore supplement” at GNC, the price is a whopping $69.99.

You’ll find it a little bit cheaper on Amazon, with the average price rounding out at $65.99.

This is actually at the higher end of the price range when compared to other competing testosterone boosters like Nugenix, Test Freak, and others.

As far as I can tell, it’s not available in stores like Vitamin Shoppe, CVS, Walgreens, or Walmart.

You can also find Alpha King on their official website ( for the same price you would find it on GNC.

A Note About The Free Trial

If you visit the official Force Factor website, you’ll see that they offer a free sample of Alpha King.

What you need to realize is, there’s a difference between a “Sample” and a “Trial”.

What that essentially means is that you will have 18 days to use the product, and then they will bill your credit card the full price of the product, in this case $69.99 (plus the cost of shipping).

force factor alpha king free trial and cancellation phone number

The only way you can stop them from billing you is if you call the Alpha King customer service phone number and tell them you would like to cancel.

Here’s their phone number in case you need it: 1-800-938-4314

Force Factor is actually REALLY reputable when it comes to cancelling, and they won’t try to scam you in any way.

I know this, because I have ordered free trials of practically ALL of their products, and when it came time to cancelling they would do so with ease.

Alpha King Testosterone Booster Pros and Cons

At this point, this is how things fall given what we know.

Advantages of Alpha King Testosterone Booster

  • I experienced fairly good results with it.
  • It contains a newly developed form of Fenugreek, one of the most popular ingredients in natural testosterone boosters.
  • The supporting ingredients include some effective components.
  • The price will be on the low end of Force Factor products.
  • Backed up by a well respected company.

Disadvantages of Alpha King Testosterone Booster

  • A good portion of Alpha King reviews are not very favorable.
  • There’s not a ton of info available on the effectiveness of Alphafen.

Alpha King Testosterone Booster – The Bottom Line

The Force Factor company burst onto the scene in 2009 with one pre workout supplement. 8 years later they’ve grown to selling more than 20 products in 7 categories.

The fact that the brand is sold in GNC stores has lent a great deal of credibility to the brand, which has allowed them to grow and expand so quickly.

With Alpha King, they’re staying in a category they know – testosterone boosters. –

However, they’ve updated their signature ingredient from Testofen to the new and improved Alphafen.

They’ve chosen an interesting strategy by adding to their growing list of testosterone boosting products, banking on the fact that providing a different choice for each small niche will have them cornering the market in the end.

After personally testing it out, I can honestly say that Alpha King is worth the price tag (and maybe even more).

If you’re on the fence, get off of it and head down to your local GNC. It will be well worth the drive.

What is the difference between Alpha King by Force Factor and Nugenix for workouts and testosterone? Which is better? -Vito

Tough call. Nugenix worked VERY well for me, but so did Alpha King. If I had to choose right now, I would still go with Nugenix. But that's also from years of using it on and off, so there's a slight advantage there.- Rob
