Product Information Factor 2™ Science
You have hundreds of options when it comes to muscle-building supplements. So how do you choose? Untested, unsafe ingredients are not the answer. Risking dangerous, long-term side effects isn’t worth any potential short-term gain. Plus, many of those “magical” mystery ingredients pumped into other products end up being useless, wasting your time and your money.

Factor 2™ is different. It was designed by the experts at Force Factor® to help you achieve your muscle-building goals safely, efficiently, and effectively. And, its clinically researched ingredients work. They work so well, in fact, that Factor 2 is endorsed by professional athletes who compete at the elite level.

You don’t need to be a pro to take advantage of the smart science behind Factor 2. Stop experimenting with pills and powders that make you feel like your heart is going to explode. Instead, harness the transformative power of Factor 2.

Factor 2™ Science
Powerful Ingredients, Incredible Results

Factor 2’s unique formula was created by biologists to help you build strength and power. Not pharmacists or university researchers – scientists serious about formulating the best products in the industry. Their mission for Factor 2: to help you add pounds of lean muscle, gain strength, and achieve the powerful physique you’ve always wanted during your newly intensified workout routine.

The unique blends in Factor 2 work to enhance your body’s nitric oxide (NO) levels. With a cutting-edge, multi-targeted pathway to boosting NO, Factor 2 is in a class by itself, leading the way for the next generation of hardcore sports nutrition products. Building upon the breakthrough science that launched Force Factor®, Factor 2 is formulated to help deliver better, longer-lasting pumps, ensuring that you get the ultimate results from your workouts. Stackable with Force Factor for mind-blowing energy and performance, Factor 2 is the powerful, preeminent supplement for helping you build muscle and sculpt the ripped body of your dreams.

The L-citrulline in Factor 2 has been shown to be even more effective than L-arginine itself at raising your body’s L-arginine levels, stimulating your body’s natural NO production as you conquer your toughest workouts. Along with Factor 2’s powerful amino acids, vitamin C and calcium work in tandem to help increase the amount of nitric oxide synthase enzyme in your body, catalyzing the NO reaction and delivering a sustained release. The result? A formulation that helps deliver incredible stamina, allowing you to see better results than ever before.

The science behind Factor 2 is trusted by fitness enthusiasts and professional athletes around the world. Factor 2’s high-quality, scientifically studied ingredients work to help you build lean muscle safely for the transformative results you crave.

Enhance Results with Stacking
Factor 2 was engineered to deliver powerful muscle-building results on its own, but works even more effectively when stacked with other premium Force Factor products. Maximize your pumps and power by combining Factor 2 with Force Factor. Get cut by stacking Factor 2 with BRX™ to add lean muscle and blast through your workouts.

Over priced and not effective
Its easy to swallow but has no effects. I took this for 2 months and I've had no increase in energy and stamina. It was a waste of money. If anyones looking into a pre-workout supplement, look into Cellucor c4 or pharmafreak.

One of the worst supplements I have used
Using this product was a very disappointing experience for me. I received a free 60 pill trial from the company, and was shipped and charged for a 120 capsule bottle the very next day. I never even had a chance to try the product. If I had I would've never have spent anymore more money on this ridiculously priced supplement. I took the pills as recommended for about two months. Within that time I felt no increase in energy, pump, or increase in muscle growth. Now comes the hugely infuriating part. I was actually losing reps in the gym. During the time that I was using Factor 2, I was feeling my muscles giving out much sooner than the usual, and my workouts were being cut short by this product. Following suit I began to lose muscle and dropped this product from my regimen. I do not recommend this product for anyone. I will go back to my tried and true 5 hour energy pre workout and warn friends and clients of this supplement going forward.

Not What It States as a energy booster
After taking the product for ~3 months, I see no energy increases, no strength increases, and the product is over priced. Would not recommend this product to anyone.

waste of money
I had high expectations for this supplement. I bought it and was very angry after taking it for a week straight and not feeling a thing.I think this product was garbage to be completely honest.

Literally did nothing
I got Factor 2 and took the pills before each workout for a month. I didn't feel any effects as the days went on so I increased the number of pills I took before each workout until I got to the maximum recommended amount to take at once, which is 4, and the pills STILL had no effect whatsoever.

Dont do it!
I took this for about a month thinking that it might take awhile for my body to get used to it but it never worked. This gives you zero energy, and I didn't see any physical improvements.

I am nearly 55 years old now and I work in a cheese packing plant. Some of this cheese is very heavy to lift throughout a 12 hour shift. I've started taking Force Factor about a month ago just to see if I could better keep up with the younger guys on my crew? The results have been wonderful indeed. My muscles do not ache during or after my shift, and I can work load for load right along side the younger stronger men. They've asked my how I've been able to do this and I just say Force Factor. To my surprise they have never heard of it before. But they have now and a couple of the guys are now eager to try it as well. Thank you very much Force Factor!!! :)
