Rapidshred Review - Does This Fat Burner Really Work? Are dangerous ingredients and lack of availability deal breakers?

Editor's Review: 3.5 / 5.0


We’re hearing a lot of buzz about Rapidshred, so we did one of our in-depth reviews, scrutinizing the ingredients, side effects, customer-service quality and scientific research. Furthermore, we focused on dozens of dieter comments and user reviews from all over the web. At this point we summed up all the data we collected to give you the facts you need.

EDITOR'S TIP: Combine Rapidshred with a proven fat burner such as Leptigen for better results.

What You Need To Know

Rapidshred is an “extreme metabolic formula” that’s made by Primal Shock Research. One capsule of this supplement is a serving, and it’s fine for women and men alike. This product is claimed to suppress appetite, burn of fat, boost metabolism and supply all-day energy. As for the ingredients in Rapidshred capsules, they include the following; 1,3-Dimethylamylamine, Caffeine, Cassia Nomane, Green Tea, Ginseng, L-Tyrosine, Phyllanthus Embemca, Dandelion, 5HTP, Geranium Oil, Uva Ursi and Thaimine.

It’s unclear when Rapidshred was first released. This supplement does not require any prescription and it may help elevate energy levels. Also, Rapidshred contains some natural ingredients, but read on…

Dangerous Ingredients – Is it Safe?

According to our Research Editor, “Rapidshred contains Synephrine, which comes from Bitter Orange or Citrus Aurantium. Synephrine mimics the effects of Ephedra (a banned substance) and may lead to heart palpitations, heart attack and stroke.”

One user commented, “Used one tablet today before meal and I’ve not been myself ever since. Feeling dizzy, frequent toilet visits and throwing up.”

“Makes me very anxious and jittery,” said another customer.

Lack of Availability!

From what we gathered, there are no online stores that actually sell Rapidshred. Therefore this product is not easy to come by. According to one person, “I found the website, but it just has a store locator for Tennessee and Texas. How do you buy this stuff?”

Another dieter said, “Where do you buy Rapidshred? It’s not for sale anywhere.”

Our research has proven that if there is one particular part of a weight loss pill or diet program that is especially troublesome (dangerous ingredients, high price, lack of availability) the odds of long-term success are not very good. In other words, if Rapidshred is difficult for a lot of people to find, this could be a serious issue.

Any Actual Science?

Here at DietSpotlight, we prefer to see some real science that supports the diet product and its weight loss claims. Unfortunately, we could not pinpoint any clinical research pertaining to Rapidshred. There is actually not much information presented on this supplement at all.

The Bottom Line: Does Rapidshred Work?

So, should you buy Rapidshred? Well, we like that Rapidshred contains some natural ingredients and we did see a few positive comments about it online. But we have some issues with this supplement because it’s not backed by any clinical research. Also, we’re concerned about the dangerous ingredients it contains and the lack of product availability online and in stores.

If you’d like to shed more pounds, we recommend you try a diet product that is backed by solid science, is easy to purchase online and does not contain any dangerous ingredients.

Among the best products we’ve seen in 2015 is one called Leptigen. Its formula is a proprietary blend of four powerful ingredients, which have been proven in published scientific studies to help accelerate fat loss and increase metabolism. We haven’t found any complaints of harmful side effects and customer comments around the web express people are seeing excellent results.

The makers of Leptigen are so confident in their product they’re offering a special trial offer, which is very encouraging.

What You Should Know

Rapidshred is a fat burner from Primal Shock. The label claims the supplement will increase metabolism, help the dieter burn more fat and give the dieter energy that lasts all day without the worry of a crash at the end of that energy. There are also appetite suppressants in the formula, according to Rapidshred.

Claims are great, but proof is what the dieter really needs. The ingredients in the formula are listed in a proprietary blend and the main ingredient is associated with negative side effects on the heart. This is not a supplement the average dieter should try without great caution.

List of Ingredients


  • 1, 3 Dimethylamylamine
  • Caffeine
  • Cassia Nomane
  • Green Tea
  • Dandelion
  • Uva Ursi
  • Niacin
  • Geranium Oil
  • Thiamine
  • Phyllanthus Embemca
  • Synephrine
  • 5 HTP
  • L-Tyrosine
  • Ginseng

Product Features

The first ingredient in the formula is 1, 3 dimethylamylamine. There have been reports of racing heart rate, hypertension and heart palpitations associated with this ingredient. We suggest dieters with health problems of any kind choose a different fat burner.

Next is 175 mg of caffeine, on top of the 1, 3 dimethylamylamine stimulation. That is quite a bit of caffeine as a standalone supplement, let alone mixed together with multiple stimulants. The ingredient list also shows synephrine and green tea - two additional stimulants.

Green tea is our favorite ingredient in the formula. It's too bad we have no idea how much green tea is in the formula. Green tea is effective at doses in excess of 300 mg. Dandelion and uva ursi are diuretics. These ingredients are added to increase urination and push water out of the body. Some dieters use these ingredients to increase weight loss, but the results they see on the scale are only temporary.

Another interesting ingredient in Rapidshred is geranium oil. This oil used to be considered a source of dimethylamylamine, but new research suggests the oil does not actually contain that stimulant.

Rapidshred is a stimulant fat burner that may or may not help the dieter increase metabolism and lose weight. The formula is packed with stimulants so energy will not be a problem, but some of the stimulants are thought to cause negative side effects. We are most concerned for dieters with health problems that could be exacerbated by the stimulants in Rapidshred.

    I had quit smoking and put on A lot of weight. it was very depressing. Doctor said I needed to lose between 6-12kg to be in healthy range. I have a very physical job also working slit shifts, since taking this product I have lost 9kg do not get any flat points in either of my shifts and can snooze fine in my break. I don’t drink coffee hardly ever now either. I have gone from a size 16 back to size 12 in about 5 weeks. I feel great, I have tried other weight loss products natural tablets and durumine they messed with my head too much! The only down fall is that it doesn’t taste the best… I really do recommend!

    Is it meant to be taken before or after meal? Used one tablet today before meal and I’ve not been myself ever since. Feeling dizzy, frequent toilet visit and throwing up.
