Rockstar Skinny Gal Review

Great looking brand
A reputable company
Positive signals from industry watchdogs
Some good customer reviews

Formula doesn’t inspire confidence
Positives reviews may be not legitimate
Not much information on how it works

Skinny Gal is a typical female fat burner supplement that seems to be proliferating the market at the moment. It looks great, striking packaging and all – it suffers from style over substance. But if you want a product that will help you lose weight we recommend you look elsewhere.

Recommendation Alternative: LeanBean is a women’s fat burner – it not only looks great as a brand but actually contains some excellent ingredients that can help you burn body fat and reduce your hunger cravings.

What is Skinny Gal

Rockstar Skinny Gal is a weight loss pill for women. You can only buy it online. It’s part of a range of health and wellness products distributed by Rockstar Sports Nutrition.

The Rockstar range also includes several other female orientated weight loss supplements, two of which are carb blockers.

Not all Rockstar supplements are aimed at women though. The company produces a lot of unisex products too. It also has some supplements for men.

Before going any further with this Rockstar Skinny Gal review, I feel it’s important for me to point out Rockstar Sports Nutrition is not associated with Rockstar energy drinks. The drinks are produced by a different company.

However, due to the fact Rockstar Sports Nutrition generally shortens its name to “Rockstar” there is some danger of confusion. The similarity between the emblems the two companies use only serves to make the situation worse.

Rockstar markets Skinny Gal as a thermogenic hyper metabolizer. That sounds pretty good but it’s just a fancy way of saying the product is intended to function as a thermogenic fat burner. That’s nothing special. There’s plenty of other diet pills designed to work in the same way.

The claim that Skinny Gal is a fat burner for women should make the product a little more interesting but the truth is there doesn’t appear to be anything in the formulation that is likely to make it work any differently for women than it would for men.

How Does Rockstar Skinny Gal Work?

Rockstar doesn’t provide any details about how the pills are likely to produce the promised results. However, thermogenic fat burners normally support increases in weight loss by increasing metabolism and thermogenesis.

Although the word “metabolism” has a far greater significance from a biological point of view, when people use it in relation to weight loss and weight gain they are referring to the body’s ability it extract energy from food and use it as fuel.

During sleep and other times of low activity, human metabolism slows down. When we are up and about it increases. Metabolism reaches its fastest point during exercise and other acts of strenuous activity.

When metabolism accelerates the body’s use of calories increases accordingly. That’s why exercise can be so good for increasing the amount of fat our bodies burn. Unfortunately, like diet pills, exercise only works if you use it alongside a low-calorie diet.

Any attempt to lose weight will only work if the body becomes so short of energy (measured in calories) it has to burn its stores of fat.  If Rockstar Skinny Gal can increase metabolism it will help women on a low-calorie diet to burn more calories than they could with just their diet alone.

Thermogenesis is the process that causes our bodies to become warm and lose energy into the atmosphere in the form of heat. Like metabolism, thermogenesis increases during exercise. Certain natural ingredients increase thermogenesis too. These ingredients and the weight loss products that contain them are known as thermogenic fat burners.

What’s the Best Way to Use Rockstar Skinny Gal?

The usage guidelines are somewhat vague. Customers are told to take one capsule every day before a meal. The fact that the instructions say “a meal” suggest Rockstar is saying you only need to take one dose per day. It seems unlikely that one capsule per day will provide women with the support they need to lose weight.

However, a statement on the back of the bottle points out the fact that a calorie-controlled diet and exercise are critical to any weight loss plan.

Ingredient Profile

One Rockstar Skinny Gal capsule provides:

  • Garcinia Cambogia (40mg)
  • African Mango (25mg)
  • Conjugated Linoleic Acid (15mg)
  • White Kidney Bean (10mg)

Proprietary Blend (235mg)

  • Caffeine Anhydrous
  • Guarana
  • Green Coffee
  • Raspberry Ketones
  • Cayenne Pepper
  • Hoodia Gordonii
  • Rhodiola
  • Turmeric
  • Papaya Leaf
  • Apple Cider Vinegar
  • L-Arginine
  • 5-HTP

What Do the Ingredients Do?

Garcinia Cambogia

A popular weight loss ingredient that comes from the rind of a tropical fruit. The rind is rich in hydroxycitric acid (HCA) which appears to be capable of helping people get rid of their unwanted belly fat.

Unfortunately, the quality of garcinia cambogia extracts can vary a lot. Some extracts are only 20% HCA and this may not be strong enough. Research suggests extracts that are 50-60% HCA provide the greatest level of benefit.

Many human studies support the use of garcinia cambogia for weight loss. Several studies also suggest it may not work, but that could indicate HCA may work differently on an individual basis. This is true for many things, including medications.

Overall, the evidence is supportive and suggests HCA may help people to lose two pounds over a period of 2-12 weeks. Studies also suggest the compound works by reducing appetite and inhibiting the body’s ability to store fat. (

African Mango

African mango is another popular supplement ingredient, but can it help you to lose weight? A few study results suggest it may support weight loss by improving leptin sensitivity, but there is a need for further research.

Leptin is a hormone. It’s produced within the fat cells and signals the brain to let it know the body has enough fat. The brain responds by dulling the appetite.  When leptin is low, the brain takes this as a sign of starvation, appetite increases and metabolism slows to preserve energy.

Due to its unique relationship with appetite, leptin is sometimes called the “starvation or hunger hormone.”

Conjugated Linoleic Acid

Conjugated Linoleic Acid (CLA) is a fatty acid. You can get it by eating beef and dairy products. The kind used in supplements normally comes from safflower oil.

CLA is believed to offer many different health benefits. Weight loss is one of them. The ingredient is also credited with the ability to improve muscle mass. For this reason, CLA is a key ingredient in many bodybuilding formulations.

Some research suggests CLA may help people to lose weight without loss of muscle mass. Unfortunately, a lot of studies show it has no effect at all. However, the results of a clinical review of 18 controlled trials suggest doses of 3.2 grams per day may cause modest fat loss. Rockstar Skinny Gal does not provide anywhere near that amount. (

White Kidney Bean

White kidney bean is a popular carb blocker. Ingredients of this nature reduce calorie intake by limiting the amount of carbohydrate the body can digest. The portion that remains undigested does not provide any energy to the body and, therefore, cannot contribute to weight gain.

When incorporated into a low-calorie diet, carb blockers may help people to lose more weight than they could by dieting alone.

Several studies support the use of white kidney bean extract as a carb blocker. The results of one study, conducted in Rome over a 30-day period, suggest 445 mg of white kidney bean may increase weight loss when combined with a diet that provides 2,000-2,200 calories per day.  Rockstar Skinny Gal only provides 10 mg per capsule. (

Proprietary blend (235mg)

The Rockstar Skinny Gal proprietary blend contains some credible ingredients. Cayenne has a good reputation as a fat burner and an effective appetite suppressant as well. Caffeine is a diet pill regular too. It boosts energy and helps prevent diet-related fatigue. Research suggests it may boost metabolism and fat loss too.

As is generally the case with proprietary blends, no inclusion rates are available for the individual ingredients. That makes it impossible to see if they are included in effective amounts.

Bearing in mind the fact that the entire proprietary blend is only 235 mg, it seems likely that some inclusion rates are going to be low. However, if the formulation is mostly caffeine, the amount it provides may be too high for some women to handle.

Are There Any Skinny Gal Customer Reviews?

At the time of this review, more than 5000 Amazon customers had left feedback for Rockstar Skinny Gal and a lot of it was good.

Unfortunately, some of the negative reviews suggest Amazon feedback for this product is unreliable. 

A number of customers state they were offered a free bottle of Skinny Gal in exchanges for leaving a review.

Here are a few Skinny Gal evaluations and opinion from paying customers who have purchased.

Accusations of this nature are not confidence building. However, despite the allegations, an analysis from the Fakespot website suggests 90% of the reviews may be reliable.

Rockstar Skinny Gal Side Effects?

Unfortunately, customer reviews suggest side effects may be a problem for some women who use this product.

Some of the reported side effects include:

  • Mood Swings
  • Sadness/crying
  • Stomach pain
  • Headache
  • Jitters
  • Fatigue
  • Dizziness
  • Vomiting
  • “Messed-up” hormones

In all fairness to Rockstar, customers who report bad experiences are in the minority. However, due to the range and severity of some of the side effects some women mention it would be a good idea to play it safe and always get a doctor’s approval before using this product.

Does Skinny Gal Work?

If you use Rockstar Skinny Gal alongside a low-calorie diet and exercise you may see some improvement in results.  But the formulation looks weak and white kidney bean may as well be omitted.

Rockstar Skinny Gal doesn’t provide enough white kidney bean to make its presence worthwhile. All it’s doing is diluting the other ingredients.

As for the proprietary blend, there is no way to predict what it will do. The lack of inclusion rates sees to that.

Additionally, It’s possible the side effects some customers report experiencing may be due to one or more of the ingredients it contains. People often get headaches and jitters when they consume too much caffeine. In some cases, it can cause vomiting too.

It’s harder to say why some women report other side effects. There are quite a lot of ingredients in the formulation and it could be that some of them clash.

Having said that, many women do report good results without side effects. Presuming the feedback is honest, that, at least, is an encouraging sign.

If you are a woman thinking of trying this product, there are a few things you need to bear in mind.

First of all, Rockstar Skinny Gal doesn’t contain anything that would make it more suitable for women than men. That just appears to be marketing hype.

Secondly, some of the more viable alternatives are genuinely made for women.

Finally, you need to think about the potential side effects and act accordingly. That means making an appointment with your doctor and taking along a copy of the list of ingredients. If your doctor thinks Rockstar Skinny Gal will be okay for you, all well and good. If your doctor tells you not to use it, go with a more suitable product instead.


Rockstar promises customers a 60-day money-back guarantee. In order to receive a refund, women who are not happy with their Skinny Gal purchase will need to contact the company and arrange to make a return. It’s okay if the product has been opened but the terms of the guarantee specify the need to return it in the original packaging.

Where to Buy Rockstar Skinny Gal

You can buy Rockstar Skinny Girl from Amazon. There are 60 capsules in a bottle. Presuming the correct dose is just one capsule per day, that would make a bottle good for 60 days of use.

There are also certain branches of Walmart that carry stock

As far as the price goes, Rockstar Skinny Girl is a cheap diet pill for women to buy. At the time of this review, the Amazon price was just under $30 per bottle.

Recommendation: If you are female and want to lose weight, check out LeanBean – a women only fat burner and hunger reducing supplement that has excellent feedback and results.
