Force Factor Alpha King Immortal Reviews

Does Alpha King Immortal  Work?

Alpha King Immortal has a couple of good ingredients and a lot of fluff.

Alpha King Immortal is a testosterone booster and male vitality supplement produced by Force Factor. Made with what Force Factor call their Ultimate Formula, it is said to help you unleash your full potential and achieve sexual supremacy and peak physical performance.

Force Factor say it is capable of maximizing masculinity and the production of essential hormones, helping you to build muscle, strength, and force, and promoting enhanced libido, sexual performance, and male sexual health. Unfortunately for our Force Factor Alpha King Immortal review it could be a lot better at this. It misses out on a couple of better ingredients for stregnths like DAA, and loads up on a few ingredients that looked good a few years ago, but have since been disproven.

Alpha King Immortal ingredients consist of dicalcium phosphate, zinc, selenium, potassium, ashwagandha root, fenugreek extract, tribulus terrestris, maca root extract, tongkat ali, PrimaVie, stinging nettle extract, DIM, nitrosigine, alpha gpc, spectra, panax ginseng, astragalus root extract, and black pepper extract.

While a number of the ingredients in Alpha King Immortal can indeed benefit your t levels, most are present in dosages that are far too low. They are then surrounded by ingredients that have never been proven to be of use in a testosterone booster, further watering down the entire formula. This is ostensibly why they're charging $160 for a months supply, which is double what the best in class testosterone boosters charge. Ultimately it's not a terrible supplement, just you can get testosterone boosters with all of the effective ingredients in Alpha King and more for half the price.

Throw in complaints by both customers and healthcare professionals about its efficacy and side effects or its insanely high price tag and there is really no reason to try Alpha King Immortal.

Customers Alpha King Immortal Reviews

Customer reviews of the Force Factor testosterone booster look decent, as Alpha King Immortal has a 4.1 out of 5 stars average rating on Amazon.

When looking at the positive reviews of Alpha King Immortal, people mentioned experiencing things like heightened energy levels, which allowed them to train harder in the gym. However, what was notably absent was the mention of any effects directly associated with heightened testosterone levels.

When looking at the negative Alpha King Immortal reviews, however, there was a litany of people complaining about it both doing absolutely nothing, being horrifically overpriced, or causing side effects like abdominal pain and diarrhoea. The latter of which isn't surprising based on the overdone ingredients profile.

Some people have also stated that their healthcare professional did not deem Alpha King Immortal safe for them to use, as it can exacerbate certain illnesses.

This seems to confirm our initial findings, which were that Alpha King Immortal is not a good testosterone booster and it is certainly not worth what they are charging for it.

Force Factor Alpha King Immortal Ingredients

Dicalcium Phosphate - 107 MG (60 MG Calcium, 47 MG Phosphorus)

Calcium is a mineral that is well known to improve bone and heart health, and studies have also shown that it can lead to more testosterone being produced in elite athletes, provided they take at least 35mg per day and work out (1).

The mineral phosphorous also benefits the health of your bones, teeth, cells, and bodily tissues, but your levels can drop drop significantly when taking calcium supplements, hence why the two are used together here (2).

This means the first ingredient in Alpha King Immortal can indeed improve your t levels, but only if you work out hard each day while taking the supplement.

Zinc (OptiZinc Zinc Monomethionine) - 15 MG

Zinc is a metal element and mineral that stimulates the pituitary gland, causing it to increase the production of luteinizing hormone, boosting testosterone levels in the process. It will also enhance your eyesight, DNA synthesis, immunity, metabolism, and recovery time and reduce inflammation and the signs of aging (3).

Unfortunately, you will only see the benefits of zinc if you consume at least 25 mg per day. This means the 15 mg in Alpha King Immortal is of no use.

Selenium (Lalmin Se1000 L-Selenomethionine) - 80 MCG

The trace mineral selenium is known to be a potent antioxidant and anti inflammatory that can improve joint, skin, and hair health. However, no studies have ever proven that it boosts testosterone, so its inclusion in a supplement such as Alpha King Immortal makes no real sense and serves no purpose (4).

Potassium (Inositol Stabilized Arginine Silicate) - 40 MG

Potassium is a mineral which, while not said to boost testosterone, a deficiency in has been said to cause low testosterone levels.

However, as this correlation has never been proven, it is very possible it will not be of any use in a test booster like Alpha King Immoral and won't be of use to people who aren't potassium deficient or suffering from low testosterone even if it is (5).

Testosterone & Estrogen Modulation Matrix - 2150 MG

KSM-66 Ashwagandha Extract (Root) - 600 MG

Ashwagandha is a herbal extract produced from the roots of the winter cherry shrub.

A staple of ayurvedic medicine for many years, it is said to bring your blood sugar and testosterone to optimal levels, boost brain and heart health, fat loss, focus, memory, muscular contractions, physical performance, strength, and sleep, while reducing stress and anxiety.

The only problem is, while 600 mg is the recommended daily dosage, it should be taken in multiple doses of no more than 300 mg. This means the 600 mg in each serving of Alpha King Immortal is too strong and could cause side effects (6). It should however still work though.

AlphaFen Fenugreek Liposomal Extract (Seed) - 500 MG

Fenugreek extract has been proven to boost testosterone levels, sex drive, and male health and reproductive functions, while also lowering blood sugar levels and helping to treat diabetes.

The issue is, for these effects to occur at optimal levels, you must consume 600 mg of fenugreek extract per day. This means, while the 500 mg present in servings of Alpha King Immortal may have some effect, it is far from what it would be capable of if it had been properly dosed (7).

Tribulus Terrestris Extract (Fruit) - 250 MG

Extracts from the Tribulus plant have long been used in ayurvedic medicine, due to the belief that it can improve libido and testosterone production, support male sexual performance and health, and boost heart health and blood flow.

Unfortunately, while many studies have been conducted, no conclusive evidence has ever been produced to support these claims, so its presence in a testosterone booster such as Alpha King Immortal is likely pointless (8).

Black Maca Extract (Root) - 200 MG

Maca root extract is widely used in traditional medicines around the world, due to claims that it can enhance your mood, sex drive, and sexual performance, provide anxiety, depression, and stress relief, and combat the symptoms of the menopause (9).

However, not only have none of these claims been conclusively proven, but even the studies that support its use say at least 1,500 mg must be taken daily to produce results. The 200 mg in each serving of Alpha King Immortal is therefore virtually guaranteed to do nothing at all.

Tongkat Ali Extract (Root) - 200 MG

Tongkat ali is a herb extract used to enhance libido and fertility and reduce estrogen production. The issue is none of these benefits have ever been proven and it is not known to do anything in doses under 300 mg. This means the 200 mg of tongkat ali root in each Alpha King Immortal serving is totally worthless (10).

PrimaVie (Shilajit Fulvic Acid Complex) - 200 MG

PrimaVie is an extract from Himalayan rocks that has a high fulvic acid content, which is said to improve testosterone synthesis, muscle strength, and your overall health, while reducing the signs of aging.

However, as all of these claims are unproven and even supporting studies say a minimum of 250 mg must be consumed each day to be of use, the 200 mg in each Alpha King Immortal serving will do nothing (11).

Stinging Nettle Extract (Root) - 100 MG

Stinging nettle extract binds to SHBG (sex hormone binding globulin).

As SHBG inhibits testosterone production, binding to it will cause your body to produce less estrogen and more testosterone. Beyond just balanced hormones, it also offers other benefits, like reducing inflammation and boosting prostate and urinary tract health.

The problem is, as a minimum of 120mg of nettle root extract is needed each day to produce these effects, the 100 mg in each serving of Alpha King Immortal won't produce the desired results (12).

DIM (Diindolylmethane) - 100 MG

DIM (diindolylmethane) is a compound made by combining indole and methane molecules. An oestrogen regulator and anti aromatase modulator, it interacts with oestrogen binding sites to prevent poor testosterone levels and keep all three hormones perfectly balanced.

Beyond this, it can also boost sexual performance, health, and functions and reduce stress, inflammation, and the risk of some illnesses, provided you take 100 mg per day (13). This makes DIM one of the only instances where you will find an ingredient in Alpha King Immortal work as intended.

HGH Secretagogue Arterial Pump Activation Blend - 1700 MG

Nitrosigine (Inositol Stabilized Arginine Silicate) - 1000 MG

Inositol stabilized arginine silicate is an ergogenic aid that improves arterial nitric oxide levels, leading to greater testosterone production, cognitive functions, and energy levels.

Unfortunately, these effects are only produced if you consume at least 1,500 mg per day, so the 1,000 mg in each serving of Alpha King Immortal is insufficient to be effective (14).

AlphaSize (50% Alpha Glycerylphosphorylcholine) - 600 MG

Alpha glycerylphosphorylcholine (alpha gpc) is similar to amino acids and improves mental health and clarity, as well as the body's ability to contract muscles, burn body fat, metabolise nutrients, and regulate cholesterol levels (15).

Unfortunately, it will only do any of these things if you take three 400 mg doses per day. This means the single 600 mg dose in each serving of Alpha King Immortal is both too big and too small at the same time.

Spectra - 100 MG

Spectra is a patented proprietary blend of antioxidants that boasts coffee arabica extract, kale, green tea extract, broccoli sprout, onion extract, apple extract, tomato, camu camu, garlic, turmeric, basil, oregano, cinnamon, elderberry, mangosteen, blackcurrant extract, blueberry extract, sweet cherry, spinach, carrot, chokeberry, blackberry, bilberry extract, Brussel sprout, acai berry, raspberry, and acerola cherry extract.

Much like with the rest of the active ingredients in Alpha King Immortal though, while some, such as green tea extract, offer potential benefits, they are present in miniscule doses and surrounded by others that are not proven to be of use, making the whole blend essentially a waste of space (16)

Rapid Bioavailability Acceleration Complex - 30 MG

AstraGin (Panax Notoginseng Root & Astragalus Membranaceus Root Extracts) - 25 MG

Panax ginseng plant extracts can boost testosterone levels, mood, immunity, and brain functions, and treat or prevent erectile dysfunction and many other illnesses when taken in daily doses of at least 200 mg (17).

Astragalus is an anti-inflammatory that can boost testosterone levels, heart, immune, and liver health, and blood flow and reduce cholesterol levels if you take 30 mg per day (18).

This unfortunately means that, while both ingredients are beneficial, Force Factor have used so little that they won't be in Alpha King Immortal.

BioPerine Black Pepper Fruit Extract - 5 MG

Black pepper extract will not improve your testosterone levels directly. However, it is put in many dietary supplements as it is a bioavailability enhancer, which means it will make all of the other ingredients they contain easier to absorb and more effective.

As with everything else in Alpha King Immortal though, the 5 mg of black pepper extract Force Factor have used is far lower than the required dose of 20 mg, so it won't be able to do its job (19).

Force Factor Alpha King Immortal Pros & Cons


  • Many of the key ingredients Force Factor use are proven to be beneficial in a testosterone booster


  • Extremely expensive and requires you to take massive servings

  • Most of the proven ingredients are present in dosages far lower than required

  • Many of the ingredients Force Factor have used have not been proven to work

Force Factor Alpha King Immortal Review Conclusion

At first glance, Alpha King Immortal looks like it may be a premium and potent testosterone booster supplement. However, once you look just a little bit closer, it quickly becomes clear that there are better options. It's definitely not the worst on the market though. The Ashwagandha dosage and the maca are pretty decent, as is the vitamin blend, however the method in which you take it is likely to cause nausea. You'd also be better off with DAA instead of a lot of the bulk ingredients in Force Factor Alpha King. 

From missing some better ingredients and adding in countless unproven ones to complaints by both past users and healthcare professionals about its effects, Alpha King Immortal could be a lot better. Ultimately sometimes less is more, at least if you want to avoid cramps.

There are much better options out there at the same price point. Generally we'd recommend TestoFuel if you're looking for a muscle focused testosterone booster as Alpha King Immortal advertises itself.
