“Check out this freaky scientific VPX breakthrough: RED LINE®: is the only matrix ever developed to shred fat through the shivering response in the body.
By shivering the body burns huge amounts of stored bodyfat for energy in an effort to keep the body warm. That’s not all! In addition to shivering, you’ll also be sweating up a thermogenic storm. The combined mechanisms of these two processes results in unparalleled fat loss!”
Doesn’t that sound great?
Shivering and sweating and the same time?
Sounds like a lovely combination of the flu and a drug overdose. Luckily, this “freaky scientific breakthrough” doesn’t appear to have any real scientific evidence to back it up. Or if there is, VPX (the makers of Redline) aren’t making it available to the public.
Don’t get me wrong… Redline is 100% pure rocket fuel.
Redline is available in liquid format, gel caps, or in RTD (ready- to-drink) format. I’ve tried the RTD, and it nearly took the top of my head off it was so strong.
I found it really, really strong. I’ve used ephedra-based products, so I’m used to stimulants, but this is the most potent supplement I’ve ever tried.
The closest thing I’ve experienced to being this wired was when I mistakenly took two 30 mg herbal ephedra stack capsules at once, thinking they were only 15 mg of ephedra each.
Redline, for me anyway, was stronger. Getting to the ingredients now…
None of the available product formats actually tell you exactly how much of each ingredient is in the formulation, but I’ll tell you this…
There’s enough caffeine in this product to kill an ox (the caffeine database at EnergyFiend.com reports Redline as containing 250 mg/caffeine).
There’s caffeine citrate, caffeine anhydrous (a very rapidly absorbed version of caffeine), plus yerba mate and green tea, both of which contain caffeine.
The yohimbe content doesn’t help either, as it also acts as a stimulant.
Now I can’t tell you if the other formulations (the gel caps or the liquid) are as intense as the RTD. But the RTD is a product you only want to use prior to…
- an intense workout
- an 80-mile marathon
- cramming for the exam of the class you attended twice last semester
Otherwise, this stuff will leave you hopping about like a one-legged man in a butt-kicking contest.
So what’s in Redline?
As I said, the formula is disclosed, but exactly how much of each ingredient is included. So it’s difficult to access the efficacy of the product. Here’s what’s in it…
1. Caffeine: a well known and common thermogenic, there is some evidence it offers mild weight loss benefits (see Am J Clin Nutr. 1989 Jan;49(1):44-50, Am J Clin Nutr. 1980 May;33(5):989-97) in addition to an energy boost.
3. Yerba Mate: contains caffeine, and may delay gastric emptying, leading to increased feelings of satiety (fullness) allowing you to feel “fuller”, longer.
5. cAMP: Cyclic adenosine monophosphate is a “cellular regulator.” In other words, this compound camp is required to “spark” many intercellular processes. An increased concentration of cAMP can have such “total-body” effects such as raised thyroid hormone levels and increased fat burning.
6. Yohimbe: The standardized extract of the bark of the African Yohimbe tree is yohimbine (this ingredient appears to be improperly labeled; it should be yohimbine HCL). This compound is often used as a natural aphrodisiac.
It is also sold as a drug (in the U.S., a popular brand is Yohimex containing 5.4 milligram of yohimbine hydrochloride per tablet) and is used to treat impotency, dilate the pupil of the eye, and stimulate fat loss (studies indicating weight loss are promising but not revolutionary — see Isr J Med Sci. 1991 Oct;27(10):550-6).
There have been studies performed on its weight loss characteristics, for which of course, it is used in this formula. Study results have been less than stellar: they range from showing no effect at all (J Pharmacol. 1986 Jul-Sep;17(3):343-7) to a slight improvement. This study concluded…
“The results obtained warrant further research on the applicability of alpha 2-receptor inhibitory drugs as a supplementary management in the treatment of obesity.”
Yohimbe also acts as a stimulant, and when combined with others (as it is here), can really deliver one heck of a punch.
It’s claimed to burn fat by increasing the body’s production of heat, as well as reducing the body’s ability to store fat.
Although a preliminary animal study shows promising results, to date there’s no evidence showing evodiamine works in people.
8. Vinpocetine: a derivative of an alkaloid derived of a plant from the periwinkle family. In Europe, Japan and Mexico it’s used as a pharmaceutical agent for the treatment of cerebrovascular and cognitive disorders.
It may have a slight effect on elevating metabolism, but at this time, that’s entirely speculative.
Bottom line on Redline?
This product contains a couple of proven ingredients, and many more which have yet to be proven to be effective for weight loss. In that way, it is no different than many of the ephedra free products available.
As indicated earlier, it’s also difficult to access the efficacy of the Redline, without knowing the exact amount of each ingredient included in the formula.
The RTD is pretty potent stuff, and I’d be hesitant to recommend it to anyone who has a caffeine sensitivity—especially after reading the visitor feedback I’ve had on this product (view Redline visitor feedback here!).
Visitor feedback is interesting; folks either love this stuff, or end up in the local emergency room after swilling it back. There’s no middle ground.
If you’re dying to try an ephedra-free fat burner, Redline is an average product—you’ll get much better results from proper diet and exercise. If you insist on trying a product, click here to check out our thermogenic fat burner recommendations.
