Cost – “What is Quality Worth?”

Our first issue related to the cost of Cellucor products. “There’s a saying that you get what you pay for,” said our Research Editor. “With this line, you get quality supplements.”

One consumer said, “I bought one of the products from Cellucor and thought it was mostly affordable.”

Another reported, “This is deff worth the price, and it’s actually $10 less on Amazon.”

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– “Positive”

When you think of Cellucor side effects, people forget that they are positive. Based upon the ingredients, users should notice beneficial changes. “I use Cellucor Whey Protein after my workouts and it really helps me speed up recovery,” commented a customer.

Another reported, “It helps with my gains and recovery.”

Others enjoyed the effect the stimulants had on  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 dieter commented, “I love having that little extra boost to get through my spinning class, these work great.”

According to our research, positive side effects has lasting results. There are benefits if customers notice positive results while using Cellucor products.

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 Dietspotlight Burn. 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 Dietspotlight Burn 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 line of weight loss and muscle building supplements. Delivered in capsule and powdered form, the manufacturer claims the line boosts metabolism, promotes muscle gain, promotes weight-loss, and curbs appetite, among other things. There are also claims the supplements boost 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 contain stimulants.


Cellucor products seem to be primarily marketed to those involved in weightlifting and bodybuilding. The muscle gaining supplements feature state of the art ingredients. 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.. We believe these products may work well if you already have a strict exercise regimen.
