Hourglass vs Rockstar Skinny Gal Fat Burner

Today we’re looking at a couple of highly rated female fat burners. This Hourglass vs Rockstar Skinny Gal Fat Burner comparison will judge two products with different approaches.

Firstly, Hourglass has the respect of many people, it comes from a reputable company and is an excellent product. Then there is Rockstar Skinny Gal Fat Burner. It sells well on Amazon and at the time of writing is a top 5 product.

However, none of this matters as fancy packaging and big promises can only get you so far. What we are looking for is proven ingredients and effective dosages. A pink label isn’t enough for a female fat burner anymore.

If either is going to really make a difference, they need to do the following:

  • Burn fat effectively
  • Be safe
  • Suppress appetite
  • Increase energy

Anything less than this will not do, we want a quality product at the end of this.

Let’s get to know them a little better first.

Hourglass vs Rockstar Skinny Gal Fat Burner: Who Makes These Products?

PropuraHourglass Review - Houglass fit

You can get a long way if your reputation is solid.

That’s just what we have here, a well-respected brand. They stay away from controversy and do everything by the book.

All their products are made to GMP regulations and to the approval of the FDA. Every ingredient is natural as well.

Propura are also the people behind the popular and effective testosterone booster Prime Male. They know a thing or two about tailoring supplements to the right market and it is even endorsed by the ex- Rocky legend Dolph Lundgren.

There are so many positive reviews for this product. Just look at all the before and after profiles as so many people take to the net to share their results.

What is also important is their 60-day money back guarantee. This always makes a company seem more legit and makes every purchase risk free.

Rock StarRockstar Skinny Gal Fat Burner

Here we have the company behind our second product today.

It is made in the USA, again to GMP standards.

There is a 30-day money back guarantee here. This should give you enough time to try it on for size.

For a brand that sells so well on Amazon, we were surprised that it was so hard to find a website for them. Of course, the legitimacy is always increased when it is easy to get hold of a company but they haven’t made themselves as easy to find as we would like.

Instead, they seem to have gone for the retailer sell route.

What we do know is that they claim it to be developed by women for women. All that matters are the ingredients and safety. Let’s see if they can cover all this.

Hourglass vs Rockstar Skinny Gal Fat Burner Ingredients

This is where we will know how good either product really is.

The early signs aren’t great for Rockstar Skinny Gal Fat Burner. They include most of their ingredients in a proprietary blend. This means we cannot see the dosages of these ingredients and don’t know if they can be effective or not.

Also, their suggested serving is just one Rockstar Skinny Gal Fat Burner pill a day. This means you don’t get to spread the fat burning benefits out.

Still, let’s see what they both have to offer.

Mutual Ingredients

Cayenne Pepper

An effective ingredient to start and one we like to see.

It is a proven thermogenic. This means it will heat the body up on the inside, causing it to burn fat to cool itself down.

Cayenne Pepper also earns its place as it is an appetite suppressant. This makes it easier for you to avoid snacking in between meals.

This is backed by WebMD, they say it has been found to curb appetite, especially in people who said they didn’t already eat spicy foods.

A supplement is a good way of getting these benefits without the spice.

Of course, the dosage is all important and the 100 mg in Hourglass is a great amount. This is contained in the proprietary blend in Rockstar Skinny Gal Fat Burner so we have no idea how much they have gone for.

Since the blend totals 235 mg and contains many ingredients, it is highly unlikely to be effective.


An ideal stimulant for a female fat burner.

This is because it is milder to others and the energy increase is always a good idea in a supplement.

Guarana even works as an appetite suppressant and is also a diuretic. This is what makes the user need to urinate more as it stops you from retaining water.

Also, it will get your metabolism going which helps to burn fat. All this is what makes it a popular addition to many energy drinks.

It is even thought to help the body to put fat to better use when it comes to using it for energy.

At 100 mg in Hourglass, it is a good amount that will really work. The proprietary blend in Rockstar Skinny Gal Fat Burner stops us from knowing if it can work there.

Individual Ingredients


Green Tea Extract

The proven fat burners keep coming from Hourglass.

It is another thermogenic so you will be burning fat, even when you are resting.

It will even enhance your endurance when in the gym making it a really useful inclusion.

WebMD tells us that it Green Tea is a milder stimulant than the likes of Caffeine Anhydrous and it contains 2-4% Caffeine. This will give you a boost in your thinking and alertness.

A great ingredient and the 500 mg included is big, especially when considering the blend total in Rockstar Skinny Gal Fat Burner.

Vitamin B6

Another good ingredient and one that works in a similar way to other B-vitamins.

It burns calories by converting them into glucose which is used for energy.

B6 will even reduce muscle soreness post workout making the 4 mg serving here a good one.

Vitamin B12

Simply put, this is an ingredient that will stop the user from storing fat.

It improves brain functioning and again, increases the energy we get from food.

A good all-rounder, it makes supplementing it a good idea. This is especially the case for vegans and vegetarians since main sources are fish, meat, and dairy.

Lower levels of B12 often result in feeling fatigued as it aids red blood cell production and the transportation of oxygen throughout the body.

The 10 mcg dosage is all you need for a boost.

Vitamin D3

A popular ingredient in many supplements, but why?

WebMD says that research has shown that people with lower levels of D3 are more likely to be obese.

As many of us are deficient, supplementing is a good idea then. We actually create our own D3 when our skin is exposed to direct sunlight.

The benefits don’t stop just yet though. It can lower blood pressure and even help us to absorb calcium.

This is particularly beneficial for women as when D3 and Calcium are combined, you are more likely to lose weight according to WebMD.

The 1,000 IU is a great amount once again.


This product is about to tick every box now.

Another appetite suppressant and one of the most effective out there.

Glucomannan is a dietary fiber that swells in the stomach and absorbs water. This is what makes the user feel full. It is also what will stop you from putting on weight when you have worked hard to burn it off.

The massive 1,500 mg here is a big dosage and on its own is bigger than the whole of Rockstar Skinny Gal Fat Burner combined.


Full of trace elements, this is a decent inclusion once again.

Chromium helps to regulate blood glucose and improve insulin resistance.

Some sources will even tell you it controls appetite by communicating with the brain. This is what helps with insulin resistance and regulates blood glucose.

The dosage of 125 mcg will give you a nice boost of the above.

Black Pepper Extract

The last of the ingredients in Hourglass and a good one.

Black Pepper Extract is only effective if the other ingredients included are proven to work. It enhances the effectiveness of other nutrients which makes it a good inclusion.

This means the appetite suppressants, fat burners, and energy boosters will be even more effective.

Rockstar Skinny Gal Fat Burner


A good start here to their individual ingredients as it is a good appetite suppressant.

It is actually used to improve the flavors of various foods and comes from the fruit. The skin is what helps with fat loss as it is high in hydroxycitric acid that is good for fat loss.

Garcinia Cambogia is thought to boost fat oxidation during exercise, this will really help to burn fat.

The dosage is the issue here. It might be a good ingredient and credit to them for including it. However, there is little point if the dosage is as low as 40 mg. Consider this to be a mild boost rather than an effective inclusion.

African Mango

The first poor ingredient really, this isn’t the most reliable.

There are some that have shown it to help in stopping fat cells from forming. We like that it is safe to use but as far as fat burning goes, we aren’t convinced.

It is WebMD who say that it might lower cholesterol because of their high fiber content. The fiber increases removal of cholesterol from the body.

They continue though and comment on how the research for this ingredient is low quality. For us, this means it is not as useful as some say it is.

The 25 mg is a small dosage once again.

Conjugated Linoleic Acid (CLA)

Made from dairy products it has strong links to fighting disease and treating obesity.

We see the sense of including it though.

WebMD tell us that it is a pretty safe ingredient and even talk of its ability to aid fat loss. However, this all falls under their ‘possibly effective’ area so it seems more research is needed.

It could be a good metabolic booster which would make it a sensible ingredient.

If you look to Examine.com though, it does say that CLA too weakly affects PPAR receptors to really induce fat loss in an appreciable amount.

The 15 mg is unlikely to have much of an effect anyway.

White Kidney Bean

Not the best ingredient but one you do see quite a lot.

It helps us to break down carbs so they aren’t stored in the body and turned into fat. It has even been linked with stabilizing blood sugar levels.

The 10 mg is another small dosage anyway.

Caffeine Anhydrous

A return to the better ingredients.

The energy boost from Caffeine is always a good idea. Especially if you are using a fat burner alongside a diet that restricts calorie intake.

It has to be one of the most versatile ingredients. You will find it has a place in fat burners and even nootropics.

You will benefit from the fact that you can train harder and at your peak for longer, this means more fat burning.

The Anhydrous element means it is a powdered form. This makes it easily absorbed and fast working.

The problem once again is the blend. Because we don’t know how much there is we can’t say if it will work. However, it would have to take up the full 235 mg of the blend to be truly effective.

Raspberry Ketones

Not the best ingredient but one you do see quite a lot.

The early studies found it to have potential as a fat burner. This is why it became a popular fat burner ingredient but since then the studies have not held it in such favor.

It is linked with helping to break down fats but this is too dubious to be given the credit it needs.

WebMD tells us that Raspberry Ketones could affect the hormone adiponectin. This is what increases the rate at which the body burns fat and reduces appetite.

The problem is, WebMD does go on today there is no reliable scientific evidence that raspberry ketone improves weight loss when taken by people.

So, it is unlikely that this will have the effect that Rockstar want.

Green Coffee Bean

Back to the good ingredients again.

This is coffee before the color has been roasted from it. This is also the process that strips it of most of the chlorogenic acid that is so beneficial.

Luckily it is still in Green Coffee Bean. This acid is what stops the body from storing fat and even reduces blood sugar levels.

WebMD discusses a study looking into adults with obesity showed that taking Green Coffee Extract for between 8 to 12 weeks meant more weight loss for those when compared to others taking a placebo.

A good ingredient then. The problem is the proprietary blend stops us from knowing if they have included enough for it to really work. The total blend dosage leads us to believe it will not.


Hoodia resembles a cactus and is a traditional African ingredient.

Some believe that it can help to communicate with the brain, telling it the body is full. There are some issues though.

Examine.com tells us that Hoodia cannot easily reach the brain and aside from failures of it to suppress appetite it may also be mildly toxic and imprudent to supplement.

This ingredient still has a long way to go to be labeled a proven fat burner.

In fact, Examine.com continues to tell us that rodent trials found that 500 – 1,000mg/kg in mice resulted in some mortality – poor mice!


A good fat burner ingredient as it has the backing of some studies behind it.

It is thought to work as an appetite suppressant and is a precursor to Serotonin which is known to improve mood.

This is also why you will find it in nootropics. It is actually Serotonin that has been linked to lowering carb cravings. Some sources will tell you that because this ingredient increases Serotonin you should not use it alongside other Serotonin boosters.

It is Examine.com that says that any weight reduction from using this ingredient appears to be almost secondary to a reduction in food intake, and is not too remarkable in magnitude.

So, it is a dubious inclusion and with a recommended dosage of 300 mg required, we are not getting enough.


A good fat burner and a traditional ingredient.

Curcumin in Turmeric is what gives it the famous color but it also lowers inflammation in the cells that are linked to obesity.

Anything around the 200 mg would be a good dosage but we aren’t getting that from this product.


In terms of fat burning, it doesn’t really earn its place here.

It is thought to help increase focus which is always useful though.

If you listen to Examine.com then they do say that it can reduce fatigue and exhaustion in prolonged stressful situations.

Without the dosage, we don’t know if we are even getting that.

Apple Cider Vinegar

This is a popular health food product and one that slows the rate our food exits the stomach. This is what helps the user to feel full, making it a useful appetite suppressant.

Many will advise you to consume it before a meal as it is thought to stops the body from absorbing carbs as much.

Examine.com tells us about one study that showed it may help with fat loss. Although it doesn’t have the largest body of evidence they say, it is still a very cheap and safe ‘home remedy’ to aid in fat loss.

This is good but it does make us think twice about its effectiveness.

Papaya Leaf

WebMD is the best resource here. It says that it contains Papain.

This is what breaks down proteins, carbs and fats. WebMD does advise that this is why it works as a meat tenderizer.

However, they continue to say that Papain is changed by digestive juices, so there is a question about whether it could be effective as a medicine when taken by mouth.

So, another ingredient that is unlikely to be effective.

L-Arginine HCI

The last ingredient but one most commonly found in T-boosters.

It has links to reducing belly fat but it needs a lot more backing from human trials.

A disappointing end.
