Give me just two minutes of your time, and I’ll tell you whether or not Cellucor supplements are worth your money. We looked closely at the ingredients, potential side effects, and scientific research. We also dug through hundreds of comments to see what people were saying. Then, we condensed and refined to give you the bottom line.

What is Cellucor?

First off, Cellucor is a business that offers an extensive line of supplements. The products are broken down into goal-oriented categories such as pre-workout, post-workout, and testosterone support. The weight-loss range includes C4 Ripped, CLK, L2, Super HD, Super HD Powder, and Super HD Xtreme. The costs range between about $30 and $100. Ingredients include caffeine, dandelion extract, Slimpro, and TeaCor.

Cellucor is a sports and nutrition business that was established in 2002. The headquarters for the company is located in Bryan, Texas. They sell products from their official website and retailers in numerous countries, also offer them. We like that we saw some natural ingredients, and positive comments weren’t hard to find but read on…

Cost – “That’s a Lot!”

Our first concern is the prices mentioned in Cellucor reviews. Even the least expensive formula is $30 for ten servings. The most expensive are $100 for a one-month supply. Many of the formulas are supposed to be used together which pushes the monthly cost up even further. According to our Research Editor, “Many consumers are discouraged when they realize they need to take many supplements to get optimal results. Especially when they have to fork out this much.”

One consumer said, “I bought one of the products from Cellucor and thought it was mostly affordable but then I realized I needed two others and I just couldn’t afford all of them.”

Another buyer of Cellucor remarked, “I live on a budget and I can’t spend hundreds of dollars a month on supplements. That’s just crazy.”

Others felt the price was fair for the quality. One said, “I really love the Cellucor product line and I don’t mind paying a little more each month for it.”

A satisfied customer explained, “I am very sensitive to most supplements. If it works for me I will pay almost anything.”

Cellucor Side Effects– “Lots of Stimulants”

Many of the Cellucor weight-loss lines rely heavily on stimulants which can cause a variety of side effects.

According to one unhappy reviewer, “I tried one of the weight-loss products from Cellucor and I was so jittery and anxious I ended up throwing the rest of the bottle away.”

Another explained, “I can’t take stimulants all the time or I stop being able to sleep. Too many of these products are filled with them.”

Others enjoyed the effect the stimulants had on their energy levels and weight-loss.

One happy customer said, “I had so much energy using this product line I almost wanted to keep using it after I got to my target weight!”

A satisfied Cellucor fat burner customer, “I love having that little extra boost to get through my spinning class, these work great.”

According to our research, cost and side effects play a significant role in the overall level of satisfaction consumers associate with a product line. That can directly affect long-term results. If Cellucor prices are too high, or dieters have adverse reactions, that’s a red flag.

The Science – “A Lot of Proprietary Blends”

At DietSpotlight, we want to make sure the Cellucor ingredients are ideal for the claims. Unfortunately, several of the products rely heavily on proprietary blends. This makes it tough to prove the efficacy. However, we must note that stimulants like caffeine, used in Cellucor fat burner, are shown to help support metabolism and weight-loss.

The Bottom Line – Do Cellucor Supplements Work?

Should I race out for a bottle from the Cellucor products? The possible side effects and heavy reliance on proprietary blends in the ingredient lists cause us to have reservations about offering our support to these products. Plus, the cost, especially when stacking multiple formulas, may be too high for some customers.

If the time has come to jump-start your metabolism, you may want to check out a single supplement that can address your weight-loss needs. Ideally, it will have ingredients that are backed by clinical testing in amounts with substantial support. And, it’s great if they have a responsive customer service department.

Among the best products we’ve seen this year is one called Leptigen. It is made with a combination of four key ingredients, which have been shown in clinical testing to help increase fat loss and jump-start metabolism. We were unable to locate any negative online reviews. But, we did find numerous reports of people experiencing impressive results.

The manufacturers of Leptigen are so excited about their product they’re offering a  Special Trial Offer, which we find both reassuring and appealing.

Cellucor: What You Should Know

Cellucor is a collection of weight loss and muscle building supplements. Delivered in capsule form, the manufacturer claims that this product revs up the metabolism (thermogenesis) and promotes muscle gain with its five main ingredients. Rapid weight loss and appetite suppression are also promised by Cellucor distributors. This product also claims to give the consumer high energy without crashes. The company credits itself on only using the best products and relies on exposure through word of mouth as opposed to aggressive advertising campaigns. Cellucor offers free shipping to its customers and touts their system for only requiring six components and say other comparable programs try to sell consumers dozens of Cellucor products. This product has been criticized for being expensive or hard to access. However, this product is now sold on the official Cellucor website as opposed to only franchise organizations in the past. Cellucor also sells individual products like Cellucor P6, C4 Ripped, C4 Mass, Cellucor C4, Cellucor CLK and more.

List of Ingredients

Ingredients vary depending on specific Cellucor products.

Product Features

Many of the ingredients are said to act as adrenal stimulants which heat up the body's metabolism. The Cellucor D4 solution is delivered in bottles of 90 capsules each. There are weight loss enhancing and water loss products that can be bundled with the primary Cellucor solution. The Cellucor plan comes with six products, three each for muscle growth and weight loss. The muscle growth products are said to increase testosterone, maximize cell hydration, and minimize the body's recovery time after workouts. The weight loss compounds are said to increase adrenal output, thyroid level,s and reduce water weight.

Advantages of Cellucor Supplements

  • Cellucor offers many different weight loss and muscle gaining products.
  • Some of the Cellucor products contain thermogenic ingredients.

Disadvantages of Cellucor Supplements

  • Some Cellucor products are quite expensive. The Cellucor D4 Thermal Shock costs over $80.00 including shipping.
  • Some Cellucor products contain stimulants.
  • Third party reviews give very mixed reviews on the effectiveness of Cellucor products.


Cellucor products seem to be primarily marketed to those involved in weightlifting and bodybuilding. The muscle gaining supplements are very high tech and feature state of the art ingredients but the weight loss products contain some ingredients that aren't very well known. The weight loss products offered by Cellucor vary from fat burners to stimulants to water weight reducers. These are favored by bodybuilders to help them drop as much water weight and excess fat as possible before a competition but may not be a long term solution for weight loss. We believe these products may work well if you already have a strict exercise regimen in place but the casual dieter might want to keep looking.

hi. Im taking the Cellucor P6 BLACK. Its been like 3 weeks. I work at the oil fields and they do random drug test. Will this product show positive on a drug test???

Steven Steele

I have been using C4 for about a year with what I thought was no side effects at all. I was feeling fine, more energy on my work outs, no fautigue afterwards. I just went for my annual physical only to find that my PSA (Prostate) levels have tripled this year. I am now in for several more blood tests, uncomfortable proceedures and I am hoping for negative results. I knew that the only change I had made this year was adding the C4 to my diet so I checked the warning label a little closer. I wish I had taken it a little more serious a year ago…..




I’m in the same boat Steven. I went from a PSA count of 1.64 to 4.10 in just one year. I was taking P6 black and then red at the time.


does the pills have a expiration date?


You said p6 extreme shows on a drug test? If so, how long does it take to test clean?


probably not because your metabolic rate doesn’t show up on a drug test ; but p6 will for a fact


P6 extreme shows? If so, how long to flush the system and appear clean?

Will D4 Thermal Shock make someone fail a drug test because of the ingredients that are in it and show up as something else?
