Dren Fat Burner Review (2018): Side Effects & Ingredients

drenDren is The most powerful thermogenic fat burner (website).

They also claim, Even hardcore ephedrine junkies who were popping 50 to 100 mg per day in their ECA stacks consider the fat burning and euphoric effects of DREN to be extreme.

The word on the street is DREN is like taking a hit of pure adrenaline stacked with ephedrine.

This Dren review will let you know what the science says and what you can really expect from Dren diet pills.


  • Drenbuterol 409 mg
  • Mesolimbic Beta Agonist Complex
  • Caffeine
  • L-5 Hydroxytryptophan
  • Beta Methoxyphenylethylamine
  • Yohimbine HCl

Caffeine is a clinically proven ingredient which increases metabolic rate to cause weight loss.

Unfortunately, Dren fails to list how much caffeine it contains, making it impossible to know if the amount of caffeine in Dren diet pills is enough to be effective.

L-5 Hydroxytryptophan is a mood enhancer. There is no proof that L-5 Hydroxytryptophan directly contributes to weight loss.

Beta Methoxyphenylethylamine is also known as PEA or The Love Drug.

It is found in chocolate and is supposed to be a feel good ingredient. However, there is doubt as to whether PEA reaches the brain before being metabolized.

Regardless, there is no research showing PEA actually contributes to weight loss.

Yohimbine mobilizes fatty acid, causing weight loss. However, Dren does not disclose how much Yohimbine it contains, making it impossible for this Dren review to determine if there is enough Yohimbine in Dren diet pills to be effective.

While Dren does contain two clinically proven ingredients, it does not list how much of each ingredient is included. This usually means there is not enough of each ingredient to cause weight loss.


You can get a bottle of 30 Dren diet pills (a one month supply) for $39.99. While this is not expensive for a diet pill, there is no research showing Dren actually works, which means any amount is too much for Dren.


Dren offers a 100% money back guarantee. You have to return the item with a description of problem. There is no time limit specified for the guarantee.

The Science

The Dren website claims their product is backed by science. The truth is that caffeine and yohimbine have been proven to contribute to weight loss IF they are used in correct amounts. Too bad Dren hides the amounts of these ingredients.

The rest of the ingredients lack ANY scientific backing that they contribute to weight loss. The Dren website uses big words and scientific language to make you think Dren is backed by science. Dont be fooled by their flowery languageDren will not cause weight loss.


This Dren review finds Dren diet pills are not worth your money. They hide how much of each ingredient is included. They use misleading language and bogus claims to make you believe this is the answer to your dieting needs.

Dont fall for Drens misleading claims. Go with a diet pill that includes proven ingredients in proven amounts.

You may want to consider a product such as Phen375 if you want something better.
