Product Information




The same characteristics attributed to kings ultimately define all successful men: power and confidence, relentless drive and ambition, and the desire to achieve greatness and leave a lasting legacy.

Never before have these qualities been more attainable. Alpha King™, the strongest male vitality supplement to date from Force Factor®, delivers an enviable boost of free testosterone when paired with the resistance training that helps men build lean muscle.

More free testosterone leads to a heightened sexual appetite and noticeable increase in libido. It means more energy and better physical performance. It amplifies passion and virility, and it promises to give you the competitive edge you need to rise to the pinnacle of masculinity.

Bottom line, Alpha King's premium formula helps you experience fully what it means to be a man, and it endows you with the ability to truly Unleash Your Potential®.

Alpha King's AlphaFen® is a new generation of fenugreek seed extract, with enhanced bioavailability to help boost free testosterone to elite levels. It is so powerful that you only need one small capsule per day to experience its full benefits.

The secret to AlphaFen's success resides in its high concentration of sapogenins, a constituent compound of fenugreek that is believed to block the enzyme responsible for converting testosterone into estrogen. Maximizing bioavailable sapogenins in the blood is the quickest way to ensure results.

Alpha King™ also includes traditional male sexual health ingredients, including DIM (diindolylmethane), tribulus terrestris, and black maca.

Overall, Alpha King is a formula you can literally feel working, helping you ascend to the crown of manliness.

Lean and happy husband
My husband has used AlphaKing since January and while he is also strict on the right diet and training, this booster has certainly helped him become much more trim and lean, enjoy better endurance, sleep and strength.
He is 48 and I guess that males who have passed 40-45 will probably see a more notable effect than younger specimens. It would be beneficial if the reviewers would include their age range.

Bubba on Jul 29, 2018
BEST ANSWER: I believe it’s all in the application. You can simplify take it and not feel a thing, but before I started it I started back at the gym. Like anything, this also requires a little more on the users part.
