What You Need To Know About Hydroxycut SX 7 Black Onyx

Hydroxycut SX 7 Black Onyx is one of those supplements that look very dangerous and hardcore, yet on further inspection of the ingredients list does not seem to live up to the claims.

This supplement is not as strong or as dangerous as the other Hydroxycut supplements in the range and although the principle ingredient caffeine may cause adverse effects, we are all familiar with those, and know to avoid it if we are sensitive.

However, we have some serious concerns. We have been through the ingredients list as posted straight from the horse’s mouth i.e. the Muscle Tech website and found the ingredients list is the same as we have covered in this review.

The problem is that there appear to be other versions of this diet pill out there (including on the GNC website) which contain Yohimbe – a dangerous stimulant with proven links to seizure, stroke and heart attack.

It is possible that Muscle Tech have recently changed the formula but you will need to be on your guard should you decide to buy this supplement.

What Are The Side Effects Of Hydroxycut SX 7 Black Onyx?

Yohimbe is a dangerous ingredient that has been linked to causing seizure and heart attacks.

Many of the potential side effects will be related to caffeine and may include jitteriness, anxiety, headaches, nausea, rapid heart rate, and anxiety.

Other side effects may include diarrhoea, reduced blood pressure, dizziness, and heartburn.

How Much Does Hydroxycut SX 7 Black Onyx Cost?

The price of Hydroxycut SX7 Black Onyx will vary depending upon where you buy it, but one typical example is 1 tub of 80 capsules (40 days supply) for $44.99.

Our Verdict On Hydroxycut SX 7 Black Onyx

In our opinion, the safest and most effective option is to give it a miss and look for something else.

Hydroxycut SX 7 Black Onyx is unlikely to work very well for weight loss and many customers say that it does not deliver as promised.

We have never approved a Hydroxycut supplement and this is not going to change now. In our opinion, Hydroxycut SX 7 Black Onyx is just not good enough to recommend so we reject it.

Hydroxycut SX 7 Black Onyx Review

Hydroxycut SX 7 Black Onyx is described on the bottle as “The most hardcore weight loss and ultimate sensory experience” and the idea seems to be that you take if for added energy levels, preferably before exercise.

It contains six ingredients and at first glance, these look quite familiar although unusual in diet supplements.

Hydroxycut SX 7 Black Onyx Facts

  • Each tub contains 80 capsules (40 servings)
  • Some versions of this supplement contain the stimulant Yohimbe but this ingredient is not listed on the official website
  • Latest in the long line of Hydroxycut supplements to come under the Muscle Tech brand

The principle ingredient is Green Coffee Bean Extract – believed to help weight loss because it contains chlorogenic acid that seems to cut through fat. It contains caffeine for added energy.

More unusually, this supplement contains Elderberry fruit extract – an ingredient more familiar to fruit wine and jam makers than it is to supplement fans but believed to have benefits to general health and the immune system.

How to Take Hydroxycut SX 7 Black Onyx

Take 1 capsule 2 times daily, 30 to 60 minutes before your two largest meals (e.g., breakfast and lunch).
For best results, use for 60 days in combination with diet and training.
If you are looking for an additional boost of energy, take an additional capsule with the first serving of the day
Do not exceed 3 capsules in a 24-hour period.

SX7 also contains Salvia root often known as Danshen and used in Traditional Chinese Medicine for a range of purposes including stroke (brain attack) and skin diseases.

The final ingredient is Satsuma Mandarin Pulp called Citrus Unshui. This Satsuma variety popular as a fruit that we eat at Christmas contains an antioxidant compound called beta-cryptoxanthin, which may help weight loss.

Evidence suggests that beta-cryptoxanthin can affect fatty tissue derived hormones in the body (adipose derived hormones or cytokines) and may help you lose weight more easily.

Hydroxycut SX 7 Black Onyx Concerns:

  • You could buy this supplement without realising it contains the dangerous stimulant Yohimbe
  • Could be a waste of money
  • Hydroxycut supplements are associated with dangerous side effects so why do they remain so popular?

Hydroxycut SX7 Black Onyx is the latest in the long line of Hydroxycut supplements under the trade name MuscleTech.
MuscleTech was a Canadian company that launched the original Hydroxycut supplement back in 2002. This was a popular although dangerous supplement linked with causing 23 reports of health damage and one death. This original version contained ephedra – a dangerous ingredient banned by the FDA in 2004 for this reason.

MuscleTech was sold to Iovate Health Services following bankruptcy, but Iovate have continued to market Hydroxycut under the MuscleTech name. It says a lot about some supplement fans that even though it was dangerous, people liked it and although Hydroxycut has since been reformulated a few times, customers often complain that it is not as strong as it used to be without the ephedra.

As well as Hydroxycut, there is also Hydroxycut Hardcore Elite – which contains high levels of dangerous stimulant Yohimbe.

There is also Hydroxycut SX7 – a sister product to this one although it has a different ingredients profile.

What Does Hydroxycut SX 7 Black Onyx Claim To Do?

Hydroxycut SX7 Black Onyx comes with some very big claims.

It is described as,

The most hardcore and cutting-edge formula on the market today

And is,

Supercharged with 6 premium ingredients in a never-before-seen combination, this superior formula is designed for extreme energy and mental focus.

It continues,

Just one dose delivers an unrivalled sensory overload unlike anything you’ve ever tried!

There are three key features:

  • Added salvia, theanine & elderberry for a powerful sensory experience
  • Extreme energy & mental focus
  • Features Satsuma orange supplying beta-cryptoxanthin

Not one of these claims is explained or backed up with any clinical evidence or proof. The only point we agree with is that this formula is a “never before seen combination”.

This is because we have never seen this formula before and in addition it is may never have been seen in a lab undergoing any clinical testing.

Does Hydroxycut SX 7 Black Onyx Work?

Some people have used this supplement successfully and have lost weight but worryingly there is a high proportion of negative customer feedback, so it obviously does not work for everyone.

One of the most interesting ingredients is the Satsuma Concentrate but this is in such early stages of research, no one can say whether it will be effective even though it looks positive.
In addition there is no real reason why Danshen (red sage) should help weight loss.

The greatest effect will probably come from the caffeine content which if you are an habitual coffee drinker, you may not even notice.

One thing is sure. This supplement does not live up to the hardcore, mood altering description on the label. This is just as well because we have seen some versions of this supplement that contain Yohimbe.

Yohimbe will not alter your mood either but it may increase your risk of a heart attack.

What Are The Ingredients of Hydroxycut SX 7 Black Onyx?

Hydroxycut SX 7 Black Onyx is a diet pill that comes with zero information about how it actually will help you lose weight. Instead, it is supposed to give you a sensory experience and enhance your energy levels.

Serving size is equal to one capsule.

  • Robusta Coffee bean Extract (200mg): According to the label, this is standardised to 45% chlorogenic acid. This is believed by some to have a weight loss effect and has undergone clinical testing although results have not been conclusive.
    According to the product advertising, clinical tests have shown that subjects taking 200mg of premium green coffee standardized to 45% chlorogenic acids lost weight, including 3.7 lbs in 8 weeks with a calorie-reduced diet and moderate exercise.
    This is an extremely poor rate of weight loss and certainly nothing to boast about.
    Scientists report, “More rigorous trials are needed to assess the usefulness of Green Coffee Extract as a weight loss tool”
    Source: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2943088/
  • Caffeine Anhydrous (135mg): This type of caffeine is in crystallised form so is easier for including in supplements, but it is otherwise just the same as the caffeine you drink in coffee.
    Most diet supplements contain caffeine and it is ideal for giving you a quick energy boost. It can increase the speed of the metabolism and help fat burning but the effects are often short lived as you become accustomed to use.
    A cup of instant coffee contains around 100mg of caffeine.
  • Elderberry fruit extract (sambucca niger) (47mg): Although elderberries are well known in home made wines and jams, this natural fruit can have medicinal properties. Elderberry syrup seems to improve flu symptoms and strengthen the immune system but although there are many claims such as a cure for HIV, cancer and heart disease, there is no real evidence.
    Source: http://www.webmd.com/vitamins-supplements/elderberry
  • L Theanine (25mg): Amino acid found only in tea. It has a relaxing effect without inducing sleepiness and is the part of tea that causes the calming effect that perks you up!
    According to studies, a minimum of 200mg of Theanine is necessary to achieve the anti anxiety / calming effect so probably inadequate quantities here.
    Source: https://www.drugs.com/npc/l-theanine.html
  • Salvia Root extract (as Salvia Miltiorrhiza) (20mg): Also known as Danshen, this garden plant known as Red Sage or Hot Lips, is a Chinese medicinal plant that widens blood vessels which can improve circulation. Will interact with medication for blood pressure.
    Source: https://examine.com/supplements/salvia-miltiorrhiza/
  • Satsuma Mandarin Culp concentrate (as Citrus Unshui) (2mg): Satsuma pulp contains a natural antioxidant compound called beta-cryptoxanthin, which is undergoing clinical investigation. In one small test on 17 women in Japan
    It appeared that taking 4mg a day for 3 weeks may prevent metabolic syndrome – the name of a group of risk factors that raise risk for heart disease, diabetes and other weight related medical conditions.

Does Hydroxycut SX 7 Black Onyx Have Any Side Effects?

This supplement looks pretty safe for most people but it is important to remember that many of the ingredients are not tested for side effects or long-term safety. However there is nothing here that seems to live up to the Hardcore dangerous image of the packaging and name.

Worryingly we have seen batches of this supplement on sale that contains the listed ingredient Yohimbe – so it is important to check the ingredients list before you buy.

Yohimbe is a dangerous ingredient that has been linked to causing seizure and heart attack.

Many of the potential side effects will be related to caffeine and may include:

  • Jitteriness
  • Anxiety
  • Headaches
  • Nausea
  • Rapid heart rate
  • Anxiety

Other side effects may include:

  • Diarrhoea
  • Reduced blood pressure
  • Dizziness
  • Heartburn

Not suitable for individuals under 18. Avoid if pregnant or breast feeding. Talk to your physician first if you have an underlying health condition or are taking prescription medication. This supplement may cause potentially dangerous interactions.

Are There Any Customer Reviews For Hydroxycut SX 7 Black Onyx?

Some people find that Hydroxycut SX7 Black Onyx helps weight loss.

This customer reported,

Have loss 18 pounds since May taking these! They curb your appetite and give you the needed energy to make it through the day. I take one in the morning and one before lunch. No jitters, no queasiness, just a great product.

Other customers have mentioned the appetite suppressing effect,

I really enjoyed this product because it worked on a fasted diet. I’d usually take it in the morning, and I wouldn’t have to eat until the evening. It helps keep you full. You may be a little jittery, so I would recommend eating a banana in the morning, but other than that, you will stay full.

Although this is not actually advertised as an effect of Hydroxycut SX7 Black Onyx, it seems to be helping people.

Some people have noticed the energy boosting effect.

“Great energy boost” is a typical comment.

Some people have notice extra energy but this has not helped their efforts,

Gave me energy, but no weight loss effects

This customer went into details about the energy boost and weight loss,

When I first took black onyx, it had me so alert. My heart was always beating at a fast pace… after a few days things seemed normal.
After taking it for a week, I literally could fall asleep after a couple of hours of taking it. I exercised and had a clean diet. It seemed as if I gained weight instead of losing. I also drank a gallon of water a day. I notice that I lost weight when I stopped taking them.

A high proportion of customers seem to have had no effects at all. As this customer reported,

I’ve been taking this for 2 weeks with proper diet and exercise and have not noticed anything different. It doesn’t suppress my appetite, nor give me the boost of energy, in fact it’s just the opposite.
