Rockstar Skinny Gal

Updated May 22, 2019.
Published Mar 27, 2018.

Rockstar Skinny Gal is a women-only diet pill that promises to work fast! It is billed as a thermogenic combined with an appetite suppressant and carb blocker, so it certainly ticks plenty of boxes. We all want quick results, but is this weight loss supplement the way to achieve this? Let’s find out!


  • We can’t think of a good reason to take this supplement


  • Inadequate ingredients profile
  • Unlikely to work as described
  • Not connected with the Rockstar drink range
  • Most of the good feedback is fake
Rockstar Skinny Gal
Rockstar is a well-known brand when it comes to energy drinks. Rockstar supplements are less well known, but still carry the positive associations of the brand. However, Rockstar supplements do not seem to be associated with Rockstar the drinks company. Rockstar supplements originate from Wyoming and seem to be on sale only via the website, and up to very recently, Amazon USA.

Rockstar Skinny Gal Overview

What you need to know about Rockstar Skinny Gal

Rockstar Skinny Gal is a female-focused diet pill that promises fast weight loss. It contains some reasonably good ingredients, but the downside is that many of these are in such minimal quantities it seems highly unlikely to work. In addition, this supplement does contain some duff ingredients like Hoodia, which is only proven to cause side effects and nothing more. Rockstar is a familiar name to consumers thanks to the energy drinks, but this supplement has no connection with the better-known energy drink brand.

What are the side effects of Rockstar Skinny Gal?

Potential side effects may include jitteriness, anxiety, sleep disturbances, vomiting, heartburn, nausea, weird skin sensations, headaches, increase in pulse rate and blood pressure, increased risk of liver damage, and allergic reaction.

How much does Rockstar Skinny Gal cost?

Skinny Gal is not very expensive. It is available via the Rockstar supplements website where 1 x bottle of 60 capsules costs $29.99. Shipping details are not provided.

It is the same price via Amazon USA.

Rockstar Skinny Gal Key Features

Rockstar Skinny Gal is a fun looking weight loss supplement aimed only at women. If you have ever bought any sportswear you will know that the colours of choice for us women are black and pink, and this trend is reflected in the supplement packaging.

In truth there is nothing gender-specific about the ingredients in this supplement, it is just about advertising and nothing else. Men could take this supplement without experiencing any abnormal effects, such as growing breasts or giving up the control of the TV remote for example!

Rockstar Skinny Gal Key Points

  • Each bottle contains 60 capsules
  • No association with the well-known drinks brand
  • Company appears to be called Rockstarpills

Rockstar Skinny Gal claims to work in a variety of ways, as a carb blocker, appetite suppressant, and as a fat burner, and the ingredients profile does back this up. The principle ingredients are; Garcinia Cambogia, African Mango, Conjugated Linoleic acid, and White Kidney Bean extract, all of which are in fairly low quantities but do come with some research that says they may work in the way as described.

The proprietary blend is less certain. This is the bulk of the supplement and it does contain a lot of ingredients, but it is impossible to predict what each of these will do as there is no breakdown of the individual quantities. With only 235mg per serving of all the 13 ingredients combined, it is impossible to judge but overall it does not seem very powerful. Some of the ingredients are known for side effects.

How to Take Rockstar Skinny Gal

Suggested use: Take 1 capsule every day and before a meal. For use strictly by healthy adults only.

Rockstar Skinny Gal seems currently very popular. We were impressed that there were so many positive customer comments for this supplement on Amazon. However, the company were offering a free bottle of Skinny Gal in return for a customer review so this could be a powerful incentive for customers to review. This offer seems to have been discontinued for now, but you may find you are approached by the company if you buy.

Rockstar Skinny Gal Concerns

  • Misleading customers by choosing a well-known company name and by manipulating customer feedback makes this company look very dodgy
  • How do you take this supplement? This basic information is not provided
  • There is an advertised guarantee but we cannot see this company really giving you a refund as claimed

The Rockstar name is best known as an energy drinks brand. It is easy to assume that the supplements brand is part of the same company because the logo, name, and advertising style is so similar. However, this is not the case. Judging by the email address, this company is actually called Rockstar Diet Pills.

The company address is:

Rockstar LLC, a Wyoming Limited Liability Company | 34 North Franklin Ave, Suite 687-930, Pinedale, WY, 82941.

What does Rockstar Skinny Gal claim to do?

According to the advertising,

Rockstar has developed an amazing thermogenic diet pill that works incredibly fast: Skinny Gal. Skinny Gal Rockstar is the brand that you choose when you want results.

The ingredients are mentioned,

Skinny Gal is jam packed with powerful ingredients that help women to burn fat fast. Raspberry ketones. Garcinia Cambogia, African Mango. CLA. We’ve got the whole formula figured out for safe, pure, and all natural weight loss.

More interestingly, Rockstar promises to give you a refund should you fail to lose weight. On the Amazon advert, it reads,

Fast weight loss. 30-day guarantee or your money back. You will love Skinny Gal so much, we guarantee it!

We tried to find out more about this. However there are no terms and conditions posted on the official website, so it is impossible to know whether the company will really honour the guarantee or whether there are strings attached. We think it is unlikely that you will get your money back without a fight, if you are dissatisfied with this supplement.

Does Rockstar Skinny Gal work?

We think it is unlikely to work very well, if at all. Although Skinny Gal does contain a couple of good ingredients among its long list, the downside is that quantities are extremely low. In addition, there are too many ingredients taking up space and contributing nothing.

With only 235mg of the proprietary blend shared out among 13 ingredients, nothing here is likely to be overly strong. Caffeine will probably account for around half of this figure in order to provide the energy boost, so this will probably leave just 135mg between 12 remaining components. Nothing here is likely to be in sufficient quantities to work. You could certainly obtain more apple vinegar, turmeric, and red pepper from your diet.

In addition, many of the ingredients are very questionable. Hoodia for example which used to be popular, but has since been discredited is present here in unknown quantities. Hoodia is known for a range of unpleasant side effects, so we can only hope that the serving size is low.

Rhodiola Rosea is known as an Adaptogen, which means it has a generally mood-boosting effect but it does need to be in sufficient quantities. Most people take around 30mg of Rhodiola per serving, but it is unknown whether this matches the profile here.

Some of the ingredients are not included within the proprietary blend. There is 40mg of Garcinia Cambogia – a tropical fruit that is supposed to help block carbs and improve serotonin levels. This extract is not proven to work very well, and with most Garcinia supplements delivering around 500mg per capsule, results are unlikely to be noticeable.

Likewise with white kidney bean extract. This fibre extract can help suppress appetite by remaining in the stomach and should be taken before a meal. Clinical testing was based on serving sizes of 2000mg to 3000mg a day, so here at 10mg per serving, looks completely ineffectual.

Overall, we think this supplement looks ineffective.

phentatrim bottle
The most popular appetite suppressant in 2021 is Phentatrim.

Its ingredients are scientifically proven to aid weight loss and you are covered by a full 60-day money-back guarantee from a trusted company, making Phentatrim a very popular choice in the diet world.

Phentatrim is the best thing to hit the supplement market in a long time, with thousands of customers already seeing the benefits. That’s why it's our editor's top pick.

Rockstar Skinny Gal Ingredients

Each serving is equal to one capsule.

  • Garcinia Cambogia fruit (40mg): Sour fruit which grows in Asia, and is high in hydroxycitric acid. According to some research, HCA prevents a natural digestive enzyme called Alpha amalyse from breaking down the carbs you eat for storing them into fat, and instead some of these undigested carbs pass through your body. Serving size is generally around 500mg, so unlikely to work here.
  • African Mango Seed (25mg): Irvingia Gabonesis as it is also known may have weight loss benefits because of its high fibre content. It is believed to promote leptin – the hormone that signals feelings of satiety, and it has undergone human clinical testing that displayed very positive results. However, all testing looked at 300mg per day as the optimum serving size. Source
  • Conjugated Linoleic Acid (safflower) (15mg): Conjugate Linoleic Acid is a group of chemicals present in Linoleic acid, a fatty acid. CLA is safe and in general beneficial to health when taken via diet, but there is not enough information to really prove that CLA in supplement form works for weight loss and is suitable for everyone. Source
  • White Kidney Bean (10mg): This is a good source of protein and fibre that can help you feel fuller for longer. Clinical testing has looked at supplementing with between 2000mg and 3000mg per day, and found that it can help weight loss. Source

Proprietary Blend (235mg):

  • Caffeine Anhydrous: Same as the caffeine in coffee, but here in a more suitable form for supplement use. Caffeine can increase the speed of the metabolism and is ideal for a quick energy boost, but effects often wear off with use. The average coffee contains around 100mg of caffeine per cup.
  • Raspberry Ketones: Natural chemical derived from the enzymes found in the fragrance of red raspberries, and which may affect a hormone in the body called Adiponectin. This hormone is important for appetite control and fat burning. Animal testing suggests Raspberry ketone increases metabolism, but it has not been tested on humans.
  • Green Coffee extract: Research results indicate that slight weight loss may be caused by chlorogenic acid present in unroasted or green coffee beans, but there is very little real evidence. The safety and the effective dose has not been established. Scientists report, “More rigorous trials are needed to assess the usefulness of Green Coffee Extract as a weight loss tool”. Source
  • Hoodia Gordonii: Cactus extract that was popular a few years ago as a weight loss miracle but has since been discredited. According to experts, the only effects are side effects. Source
  • 5HTP (5-Hydroxytryptophan) derived from Griffonia Simplicifolia seeds: 5HTP is a chemical in the body that helps make serotonin, the brains feel-good chemical. It is also derived from Griffonia seed extract.
  • Turmeric: Well known cooking spice with well-documented health benefits.
  • Guarana: Guarana, or Paullina Cupana, is a climbing plant that grows in Brazil and features a caffeine-rich seed which is higher in caffeine than the coffee bean.
  • Rhodiola: Rhodiola Rosea is taken in its own right because it can help boost mood and feelings of well being. May cause side effects.
  • Cayenne Pepper: Culinary spice. In very high quantities it can make you sweat and therefore use up calories.
  • Apple Cider Vinegar: Believed to have numerous health benefits. Best to take it in natural form.
  • Papaya leaf: Contains an antioxidant chemical called Papain which has numerous health benefits. Papain is also known for causing allergic reactions. Source
  • L Arginine: Amino acid produced in the kidneys that helps relax arteries increasing blood and oxygen flow.

Rockstar Skinny Gal Side Effects

Although this supplement is not overly strong, many of the ingredients in Rockstar Skinny Gal are known for causing side effects.

Potential side effects may include:

  • Jitteriness
  • Anxiety
  • Sleep disturbances
  • Vomiting
  • Heartburn
  • Nausea
  • Weird skin sensations
  • Headaches
  • Increase in pulse rate and blood pressure

Caution: Do not exceed suggested dosage. Women who are pregnant or nursing, children under the age of 18 should not use this supplement. Always keeps out of reach of children. Refrain from use if you have a medical condition. Always consult your physician if you have questions or concerns prior to taking this supplement.

Rockstar Skinny Gal Customer Feedback

There are nearly 2000 reviews for Skinny Gal on Amazon. Some customers have questioned the authenticity of the positive reviews, because of Rockstar’s policy of giving free products in return for customer feedback.

As this lady mentioned,

Did not see any results and was sent a flyer in the mail that I would get a second bottle free for a review which makes me question the reviews I read and whether or not they are accurate or just people wanting another bottle…

It is a very good point and many customers have asked the same question.

According to review tools, many of the customer reviews are fake. This one, however, appeared to be from a genuine customer and was positive. However she did mention the free bottle of pills,

Just received SKINNY GIRL, Took one immediately and less than 30 minutes I got a reaction. I have taken prescription diet pills and they make me feel jittery and nervous and dry mouth out. Will let you know in two weeks if or not they do anything for me, but I am not hungry and its past lunch already. Wanted to do an update, have been taking for 12 days and also drinking the apple cider vinegar with no exercise and have lost 5 pounds. This is an update on free bottle of pills. Do not count on it, I emailed them to keep them since I have to beg for them LOL!!

Strangely halfway through the review, the Amazon advert was removed and was no longer available. Although the advert has now been made available to access again, we wonder why this happened.

Rockstar Skinny Gal Money-Back Guarantee

There is a guarantee advertised on the official website that states you will receive a refund if you fail to lose weight within 30 days, but don’t hold your breath. We think it is extremely unlikely that Rockstar will honour this claim and without any terms and conditions to back you up, it seems unlikely.

Where To Buy Rockstar Skinny Gal

You can buy Rockstar Skinny Gal direct from the official Rockstar supplements website. Please note this does not seem to be associated with the better-known energy drink.

It is also on sale via Amazon USA.

Watchdog Verdict

We are not impressed with Rockstar Skinny Gal. This supplement has used the Rockstar name to trade off the well-known energy drink, but in reality is nothing to do with the better-known drinks company and is very misleading to customers.

It would not be so bad if Skinny Gal actually worked, but in truth, this supplement is just not very good. It contains a lot of ingredients, many under a proprietary blend and even the ingredients which do have their quantities disclosed are extremely underpowered. It will not work as described. Although there is a lot of positive feedback on Amazon, most of the positive comments have been left in return for a free bottle whereas genuine customers have been disappointed with this supplement.

Overall, we do not recommend Rockstar Skinny Gal to our readers.

4 comments on 'Rockstar Skinny Gal'

  1. I have been using skinny gal for about a week, and I LOVE it! Definitely curve my appetite, and gives me a TON of energy! 

  2. I find that this is not true at all I take them and I have lost 9 pounds only in 2 and a half weeks I work out not that much but I eat what I normally do I so far love the pills and would tell everyone to try them

  3. I dont agree. They did help me with motivation….so much so i take 2 a day. Wished it had more of what ever it is in it but they are really good and work. Ive done nothing less tgan hr and half workouts since i started. I take havoc pre workout less now and the two together make this perimenopausal woman feel like i did 10 years ago.

  4. After seeing over 3,100 glowing 4.5 star review on Amazon site I bought a bottle for around $30 bucks. I usually never buy stuff like this but thought maybe it would help shed these last 10 pounds. Following the one pill with a glass of water each morning on empty stomach for about a month I not only did not lose any weight … I gained 5 pounds! I’d already lost about 20 pounds and kept it off for at least 6 months.

    It is very interesting that Amazon will not allow me to make a review on this product! This makes me question their transparency. You know I bought a bissell vacuum from them about two years ago that gave glowing reviews as an Amazon’s Choice (their pick) and it was hands down the worst vacuum I’ve ever owned! Brand new it spit dirt back at my feet when using.

    In short if you are seeing thousands of glowing reviews on Amazon I would guess that Amazon might have a higher stake in the profits. Can’t say for sure.

    This diet pill is worthless in my view.
