Redline Ultra Hardcore Review - Does This Diet Supplement System Work? Are lack of results and negative side effects deal breakers?

Editor's Review: 3.5 / 5.0

redline-ultra-hardcore-product-imageWhy are people talking about Redline Ultra Hardcore? We conducted an in-depth review on this product from VPX. We looked at the ingredients, common side effects, customer service quality and any published scientific research. Hundreds of dieter experiences were also part of the equation. We then summarized, condensed and refined to give you the info you need.

EDITOR'S TIP: Substitute Redline Ultra Hardcore with a proven fat burner such as Leptigen for better results.

What You Need to Know

To start, Redline Ultra Hardcore is designed to give you the energy you need to power through your workouts. The list of ingredients includes caffeine, trans-resveratrol, toothed clubmoss, vinpocetine, n-acetyl l-tyrosine, yohimbe complex, barley and olive leaf extract. This supplement comes in capsule form and users take two pills twice per day on an empty stomach. Redline Ultra Hardcore is convenient and can be taken anywhere, making it a good option for dieters with a busy schedule.

VPX or Redline Sports Nutrition and Performance Beverages has been around since 1993. They produce a wide variety of supplements and energy drinks. The products are readily available online and the company’s longevity is an encouraging sign, but read on…

Lack of Results – “Main Issue?”

Our first concern with Redline Ultra Hardcore ingredients is the fact that they are ineffective. “Redline Ultra Hardcore is designed for lifting weights and strength exercises,” said our Research Editor. “It does have some energy-boosting elements, but that’s not the same as a weight-loss formula.”

“I didn’t lose any weight with this product, but I did have a lot more energy,” said one user.

“Redline Ultra Hardcore gave me the energy I needed to work out, but I found that I was gaining weight with my work outs rather than slimming down,” said another.

Harmful Side Effects – “Another Concern”

Redline Ultra Hardcore has plenty of adverse side effects, as reported by dieters who’ve tried the formula. “This product led to jitters and heart palpitations for me, especially when I take it on an empty stomach,” said one customer.

“After the first day on Redline Ultra Hardcore, I had to go to the doctor with heart palpitations and my doctor recommended that I stop taking it immediately” said another.

Our research has shown that diet supplements or workout routines with elements that are particularly difficult or troublesome (cost, negative side effects, painful routine, etc.) are less likely to lead to long-term success. If Redline Ultra Hardcore really does cause adverse reactions, this could be an issue.

The Science – “Legit?”

Redline Ultra Hardcore has some data suggesting that the ingredients they’re using are beneficial for energy, but no published studies have been conducted linking Redline Ultra Hardcore to improved weight-loss. We value unbiased information on diet supplements, so when a product is missing published studies, it’s a red flag for us at DietSpotlight.

The Bottom Line – Does Redline Ultra Hardcore Work?

So, we’ve got all the info we need on this one. We like the longevity of the company behind Redline Ultra Hardcore, how easy it is to buy this and the affordability, but because of the lack of published clinical data this is not a product that we’re comfortable endorsing. We also have concerns about the lack of weight-loss and high likelihood of negative side effects, based on dieter reviews.

If you’d like to lose weight, but you prefer a healthy alternative, we suggest a good formula that will help you shed the pounds without negative side effects. One that contains ingredients proven to help you burn fat and boost your metabolism.

Among the best products we’ve seen in 2015 is one called Leptigen. This weight-loss supplement contains four revolutionary ingredients combined in a proprietary blend that has been shown in published scientific trials to help accelerate weight-loss by burning fat and boosting your metabolism. We can’t find anyone claiming to have experienced negative side effects and most customers have seen great results.

Plus, the makers of Leptigen are offering a Special Trial Offer. It’s always good to see a company stand behind their products with risk free offers.

What You Should Know

Redline Ultra Hardcore is another in a long list of VPX supplements that promote energy and fat loss. VPX is known for strong stimulants and potential side effects. Redline products are particularly high in stimulants. Bodybuilders and fitness gurus tend to gravitate to VPX products but many of the supplements, like Redline Ultra Hardcore, are formulated for all dieters.

List of Ingredients

Fat Catabolizer and Beta 3Potentiator: Caffeine Anhydrous, Trans-Resveratrol, 1,3 N-Dipropyl-7-Propargylxanthine, Guggul Extract, 3'-5'-cAMP, 5'-UMP, Toothed Clubmoss, Super Amine Apple Geranium.

Iphoric Potent Methyl Beta-PEA Matrix: R-Beta-Methylphenylethylamine HCL, N-Methyl-Beta-Phenylethylamine.

NorEpiphex Alpha2-Andregenic Blockade Complex: Yohimbine HCL, 11-Hydroxy-Yohimbine, Alpha Yohimbine HCL.

NorEpiphex M-MAOxidizor-I: Barley, Olive Leaf Extract.

Thyromimetic Activity Stimulator: 3,5'-Diido-L-Thyronine, 3-3'-Diido-L-Thyronine.

Product Features

VPX Redline Ultra Hardcore does a great job at marketing ingredients as being more than they really are. The complexes and matrixes included in the ingredient list tell what each matrix is used for but the average dieter will not understand most of the terminology. The Fat Catabolizer is the fat burning portion of the supplement. Iphoric stands for mood changing. Thyromimetic is another term for thyroid.

Moving back to the Fat Catabolizer, the ingredients in this portion of Redline Ultra Hardcore are pure stimulants and metabolism boosters. Caffeine is proven to increase metabolism, so we like that ingredient, but there are 290 mg of caffeine in each serving. That is a huge amount of caffeine to take in one sitting.

The Iphoric Matrix is particularly concerning. If a dieter suffers from anxiety, panic attacks or depression, phenylethylamines are not suggested in any form. Even dieters who have suffered in the past may be at increased risk of symptoms associated with these ingredients. Dieting and weight loss have been linked to anti-depressants or mood stabilizers, but prescription medication effects are monitored by professionals - nutritional supplements are not. Thyroid boosting may be helpful if the dieter has reduced thyroid function.

The feeling we get from Redline Ultra Hardcore, even after looking at only a few ingredients, is one of skepticism. It looks like the ingredients are packed with stimulants to make the user feel the effects of the supplement. The rest of the ingredients are there for good measure, but VPX does not bother supporting the effects claimed in the product description.

Redline Ultra Hardcore sells for about $40 per bottle. Users are advised to start small and take half doses until they get used to the stimulant effect.

  • A few ingredients are proven to increase metabolism.


  • Too many stimulants.
  • We do not like the lack of clinical support for ingredients.
  • Confusing names used for common effects to impress, or confuse, dieters.


Overstimulation could easily be a side effect of taking this supplement. We suggest choosing a diet pill with fewer stimulants and a label that is easier to comprehend.

    Hi I have been taking Redline Ultra Hardcore for about 3 months and although it does give me energy without feeling jittery I have gained about 12 to 15 pounds. I used it with diet and exercise so I was very surprised. I stopped taking two days ago so I am trying really hard to get the weight off.
