Following on the heels of 2009’s original Force Factor, Factor 2 was designed by Force Factor to help you build muscles and gain energy more efficiently.

While Force Factor relied on arginine to boost nitric oxide levels, Factor 2 uses L-citrulline to open blood vessels in the body and help you work out longer and harder to the tune of better results.

But because Factor 2 is a relatively new product, I think it merits a closer look. In this review, I’ll get to the bottom of Factor 2’s reliance on L-citrulline, whether the product is effective, and whether there are any side effects with which you should be concerned.

What Does Factor 2 Do?

The main goal of Factor 2 is to increase the amount of blood delivered to the muscles through the use of L-citrulline and nitric oxide. These twice-a-day pills enable a continuous release of nitric oxide, allowing more nutrients and oxygen to reach your muscles.

By expanding the capacity of blood vessels, Force Factor claims that Factor 2 amplifies strength, increases power, and greatly lengthens your personal stamina.

What Ingredients Are In Factor 2?

L-citrulline is the prime ingredient in Factor 2. Advertised to be twice as effective as arginine in boosting nitric oxide levels, this amino acid is an offshoot of arginine and relaxes blood vessels, allowing them to expand. L-citrulline is also vital in the production of nitric oxide.

Nitric Oxide is a binary molecule that is extremely popular in bodybuilding supplements for its ability to increase blood flow to the muscles.

The heightened amounts of nutrients delivered to the muscles while under stress help the muscles grow and prevent them from being damaged by overexertion, meaning you can work out longer.

Vitamin C is an essential nutrient that Force Factor claims also aids in the production of nitric oxide. It also helps to prevent the damage that oxygen can do to the muscles.

Calcium helps to regulate muscle contractions and eliminate fatigue in the body, helping you to a stronger and lengthier workout.

Are There Any Side Effects Associated With Factor 2?

Any concern levied against Factor 2 has to do with its inclusion of nitric oxide. While nitric oxide is widely accepted as a way to increase nutrient delivery to the muscles, it has also been associated with negative side effects like mild headaches and migraines, as well as nausea and diarrhea.

More serious side effects have also been observed. Changes in heartbeat, vomiting, and collapse have been known to occur in bodybuilders using Factor 2.

Some studies have even pinned nitric oxide as being responsible for hypotension in 13 percent of body builders.

Should I Try Factor 2?

Considering Force Factor’s reputation and its inclusion of commonly used bodybuilding ingredients, I’m fairly confident that Factor 2 will help give you the kind of endurance and muscle mass you’re after.

Positive customer reviews echo these sentiments, with many reviewers praising the product’s energy boost and ability to build muscles.

However, if you have a history of reacting strongly to changes in your body, you may want to be careful with such a nitric oxide-reliant product. Shop around for a product with less of a concentration of this molecule, or one not so reliant on its effects.

You can buy Factor 2 from the official Force Factor site for $69.99 a bottle.
