Viper Review - 6 Things You Need to Know

Viper is a fat burner that claims “multi-phase release technology that delivers ‘all day’ energy and intensity.” Viper does have most of the ingredients found in other fat burners, but their proprietary blend contains 18+ ingredients for a total daily dose of about 700mg. Is there enough of anything in this supplement (other than the vast amount of stimulants) to have any positive effect?

Our research team conducted extensive research on the science behind Viper’s ingredients to find out if there was any truth to the claims. Here are the findings, condensed, and summarized, about Viper’s effectiveness.

What You Need to Know

To start, Viper is a fat burner containing caffeine, synephrine, theobromine, guarana seed, phenylalanine, xanthine, zingiber, cayenne, Yohimbe HCL, Bioperine, maximowizia Chinensis, phaseolus Vulgaris, r-alpha lipoic acid, guggulsterone, Rhodiola Rosea root, tyrosine ethyl ester, l-carnitine, thiamine disulfide, and thiamine trisulfide. The recommended serving is one capsule per day, which may promote weight-loss. You can use the supplement on the go, a positive.

There’s limited information about when Dymatize Nutrition introduced Viper, but the business was founded in 1997. You can no longer purchase the supplement on the official website, but you can visit other online retailers. We like that the company includes a few natural ingredients and that we located some favorable customer comments.

This product is no longer available, as it has been discontinued.

Ineffective – “Any Results?”

The first negative aspect of Viper ingredients was ineffectiveness. “You’ve headed into the store and purchased a supplement that you’re willing to give a try,” said our Research Editor. “Only this time you don’t see the results the company claims. That could be quite a problem.”

“Really didn’t care for this product. Not a whole lot of energy and overall left me feeling drained most of the day,” commented a customer.

“This product did next to nothing for me. Maybe a small energy perk, but other than that nada,” stated a user.

Side Effects

Side Effects – “Feeling Bad”

We also found that dieters tell quite the story about Viper side effects. “If you don’t mind feeling dehydrated and having a kind of shaking feeling after a workout, this is a great product to try,” reported a user.

“It increases your heart rate; being inactive makes you feel kinda sick,” commented a consumer.

We’ve researched hundreds of supplements, and we’ve found that something minute, like a simple side effect, could derail long-term success. If Viper causes reactions, will dieters continue to use it?


Is the Science There to Back Up Claims?

Based on the official Viper website, the product is tested by a team of scientists, but there’s no published clinical research supporting weight-loss claims. Studies prove the effectiveness of caffeine, but none that proves this formula is any better than other caffeinated supplements. At DietSpotlight, finding science is critical. If a company can’t provide proof, there’s a concern.

What Users Are Saying

What Users Are Saying

“I thought this product worked well and did exactly what I needed. I actually used them more for the energy I got from them instead of for the burner aspect. I wish I could still buy them on Amazon!”


“I wish I could find more of this stuff… too bad they discontinued it.”

Bottom Line

The Bottom Line – Does Viper Work?

Is the car engine revving for this one? We’ve researched Viper, and here are our findings. We like that we found some positive customer comments and that the company has been operating for years. Still, we are hesitant about recommending a supplement not supported by clinical studies. Additionally, we’re concerned about the product not being effective and that there are potential side effects.

If you’re at the point that you want to lose more weight, we suggest trying out a clinically proven program to help the user lose weight.

Among the best products we’ve seen this year is one called Noom. The weight-loss app combines proven elements like human coaching, one-on-one support, personalized meal plans, and more to help you down the road to weight loss once and for all.

Plus, the company behind Noom is confident enough in the program to offer a free trial offer, which is a good thing.
