Factor 2 Review - Does This Pre-Workout Supplement Work? Are ineffectiveness and poor customer service deal breakers?

Factor 2 Review

Well over half of all diet supplements out there today have absolutely NO scientific backing. Is Factor 2 one of these? We decided to do a complete 360-degree review of the ingredients, side effects, clinical research and the quality of customer service. We also investigated consumer comments. We then condensed and summarized to give you the info you need.

EDITOR'S TIP: Click here to combine Factor 2 with a proven testosterone booster such as Pronabolin for better results.

What You Need to Know

To start, Factor 2 is a pre-workout supplement containing l-citrulline, lovage root extract, CoQ10, l-taurine, l-norvaline, folic acid and vitamins. The recommended serving is two capsules per day, which supposedly supports increases in muscle and strength. One of the benefits of the product is the ease of use.

The supplement, introduced in 2009 by Force Factor, doesn’t appear to use artificial ingredients, a good start. The product is available to purchase on the official website and via outside retailers. We do like that we located some positive customer comments and the company has a favorable BBB rating, but read on…

Ineffectiveness – “No Results?”

The first concern about Factor 2 ingredients is that they are ineffective. “When consumers use pre-workout supplements, there is an expectation that the products will produce results,” said our Research Editor. “If they don’t, users will not buy into anything the company is selling.”

“After taking the product for ~3 months, I see no energy increases, no strength increases, and the product is overpriced,” commented a customer.

“I tried this and it did nothing for me. I tried 4 (max) capsules before each workout and felt absolutely nothing,” reported a user.

Customer Service – “Poor Quality”

Based upon comments in forums, the Factor 2 customer service department is unsupportive. “I have tried many times to phone the company back but all I get is a recorded message saying the office is closed. They haven’t got an email address or any place you can leave a message,” said a user.

“I have taken action to cancel any further debits from my account in writing. They do not have an email address and the phone number has a message to call back during business hours,” offers another.

“Next thing every month I get a new batch and an Invoice for over a hundred dollars taken out my card. When you try to contact you are not able, phone numbers do not answer,” reported a customer.

Our research shows it takes only one small factor, such as poor customer service quality, to hinder your chances of long-term success. If Factor 2 doesn’t provide supportive consumer care, there is a problem.

The Science – “Is There Any Research?”

According to Factor 2, the supplement is backed by science, but we couldn’t locate clinical research on the official website linking the formula to these claims. The product statements aren’t exactly false. Some of the ingredients do support nitric oxide production, but the company doesn’t bother to show proof that taking more than is already in the body is beneficial. At DietSpotlight, we need facts and if those aren’t available, the user should probably switch things up.

The Bottom Line – Does Factor 2 Work?

Let’s get all the facts in line, shall we? After a complete assessment of Factor 2, we’ve reached a verdict. There are some positives; we located some favorable comments and we like the “A+” BBB rating, but we have doubts about it because of the lack of published clinical research supporting muscle and strength building claims. Plus, we’re concerned that Factor 2 is ineffective and the customer service department is unhelpful.

If you’d like to gain more muscle and strength, we recommend going with a supplement shown in published clinical research showing the formula promotes boosting free testosterone, fat burning and enhanced muscle mass.

Among the best products we’ve seen in 2016 is one called Pronabolin. The formula contains a nine-ingredient proprietary blend, which has been backed by published scientific studies to help build strength, boost libido and spark energy. There’s no one talking about negative side effects and the reviews on the web show people are seeing exceptional results.

Also, the company behind Pronabolin is showing confidence in the supplement by providing a 120-day money-back guarantee and multiple-bottle discounts, an excellent decision.

What You Should Know

Muscle building supplements litter the industry. Which one is the best? When you consider a muscle-building supplement, individuals consider the production of lean muscle, increased strength and improved endurance. Dieters and athletes alike need a product containing proven ingredients and not mystery ingredients commonly associated with weight loss and dietary supplements. Force Factor is a manufacturer of several dietary supplements, in particular Factor 2. The product is available n the official website and claims to improve muscle development. Is Factor 2 the miracle diet pill everyone is looking for? We will find out.

Product Features

Factor 2 is a nitrous-boosting supplement designed to improve the production of lean muscle, increase strength and improve overall health and wellness. The product is available on the official website as well as on ecommerce sites. The cost is $70. This is expensive compared to similar products. Throughout the website, there is information relating to the product and the effectiveness. What is not present is scientific research or clinical trials. The only information we found relating to the effectiveness was one online testimonial. Other than this particular one, there is not information available. Not having scientific research associated with a product raises a red flag with us. It leads us to believe the company could potentially include just about anything and say the product works. We have to note there is no proven weight loss ingredients listed. You will notice energy boosters and vitamins. This leads us to believe Factor 2 is not ideal for the average dieter. The product is designed more for the bodybuilder and the professional athlete.

Factor 2 could potentially be an effective product. Unfortunately, there is no proven ingredients available proving effectiveness. There is no scientific research proving any of the ingredients are effectiveness with weight management. We tend to avoid unproven products. Compared to similar products on the market, Factor 2 is rather expensive. We feel the average dieter will not pay $70 for a product that does not guarantee weight loss.
