Oxy Max XT’s Ingredients

Performax Labs Oxy Max XT Ingredients

Oxy Max XT is only the second fat burner on the market to contain a relatively new ingredient, N-phenylethylamine HCL. Note that this is 200mg caffeine and 25mg Forskolin!

Oxy Max XT uses a combination of two blends to fry fat and leave you in a state of utter euphoria. Looking at the label, it looks like a potent formula, but we don’t have exact doses for every ingredients. However…

Caffeine and Forskolin Doses Disclosed!

Knowing that we hate proprietary formulas, Performax Labs’ CEO has disclosed caffeine and forskolin:

Caffeine is 200mg per capsule and Forskolin is 25mg per capsule. –Performax Labs CEO

This means two things:

  1. It’s a strong fat burner, most people will only need one cap at a time.
  2. Nothing here is pixie-dusted – at least nothing that we don’t want to be pixie-dusted.

Thanks to Performax for opening it up a bit. We don’t always need to know everything, but we do really want to know the caffeine so we know how to dose things at first.

Now let’s see what each of the components to Oxy Max XT has to offer and see how this might separate itself from the rest of the fat burner market!

  • N-Phenethyl Dimethylamine

    This is the key ingredient to Oxy Max XT. So far, we’ve only seen this ingredient an Giant Sports’ Dexamine Black. Studies are few and far between on this PEA (phenylethylamine) metabolite, but you can check out our write-up on Dexamine Black for a detailed rundown on how this unique ingredient functions.

    Basically, this functions in the same way PEA does, but crosses the blood-brain barrier easier due to it being more lipophilic. This should translate into a longer-lasting effect of the typical “euphoric” sensation that is attributed to the catecholamine release caused by PEA.[1]

    Update: Since writing this analysis, we’ve done a ton more research on this ingredient, which is sometimes labeled as “Eria Jarensis Extract”. You can explore the in-depth science in our post titled Eria Jarensis Extract / N-phenethyl dimethylamine: The Next Big Thing?

    N-Phenethyldimethylamine Ingredient

    N-Phenethyldimethylamine is like a PEA molecule, but with an N,N’ Alkyl section that also prevents MAO from cleaving it… although not as well as DMAA’s mechanism. Click the image to read more.

  • Beta-Phenylethylamine

    As mentioned above, PEA causes a potent, but brief release of catecholamines (dopamine, adrenaline, and noradrenalin), which lead to that “feel good” mood.[1]

    Not much research has been done on PEA in regards to weight loss. However, due to its ability to release noradrenaline it may indirectly stimulate lipolysis due to the fact that noradrenaline is a potent inducer of lipolysis.[2,3]

    Broscience Alert on PEA:

    It’s our belief that sometimes, the PEA is actually best for the quick, motivational mood boost that you get. You feel it fast, and it’s a perfect uplifting jolt to get you out of the house and into the gym to put in the work you need to do.

  • Amentoflavone

    Performax Labs

    Performax Labs makes some aggressive products, and OxyMax XT is definitely in that vein.

    Amentoflavone has been gaining popularity in a number of fat burners and pre workouts hitting the market within the past year. This is probably due to a few factors.

    It inhibits phosphodiesterase (PDE), an enzyme that degrades cAMP. Inhibiting PDE, results in increased cAMP, which ultimately leads to additional fat loss.[4,5] Amentoflavone also is a potent stress reducer[6] and mild-stimulant.[7].

    So, not only will you be frying fat, but you’ll get a nice boost in energy and be more relaxed while dieting.

  • Hordenine HCl

    Hordenine is a plant extract found alongside synephrine in bitter orange that acts as a natural stimulant. Research is on the light side, but may indicate that hordenine exhibits similar effects as that of noradrenaline.[8]

    Additionally, Hordenine acts as an MAO (Monoamine Oxidase) inhibitor.[19] This has the added bonus effect of helping keep PEA “active” longer in the body, helping to further that “feel good” sensation we described earlier.

  • Coleus Forskohlii

    Alison Sawyer of Performax Labs

    A while back, we featured Alison Sawyer as a PricePlow Admired Athlete, and she’s now with Performax! Click here to read her interview from 2013.

    Coleus Forskohlii (Forskolin) is an herb that was traditionally used in Ayurvetic medicine. Forskolin increases cAMP levels in the body thereby affecting improving fat metabolism as we mentioned above.[9]

    Additionally elevated levels of cAMP create a similar effect as exercise does in relation to the the activity of certain mitochondrial enzymes in the body.[10] This can result in increased muscle protein synthesis, which is incredibly beneficial, especially when cutting.

  • Caffeine Anhydrous

    The staple ingredient in every fat-burner, caffeine is the first ingredient in Oxy Max XT’s ThermoMax blend. Rightfully so, as caffeine has been shown countless times to be beneficial for focus, mood, energy and fat loss.[11,12,13,14]

    Given this is part of a proprietary blend, we have no clue how much caffeine is actually contained in here, but given that it’s the first ingredient in a 275mg blend, it’s safe to assume there’s about 200-225mg of caffeine per pill.

  • Higenamine HCl

    Higenamine is an extract that exhibits similar fat oxidation effects to ephedrine although not nearly as potent.[15] It’s a beta-2 agonist, meaning it makes the body release noradrenaline which then causes fat to be released and used for energy.

  • Rauwolscine

    Rauwolscine, also known as alpha-yohimbine, is chemically similar to yohimbine and functions in much the same way. It is an alpha-2 adrenergic agonist and can help accelerate fat loss.[16]

    It doesn’t directly burn fat, but rather inhibits the receptors in the body that prevent fat loss. By blocking these receptors, Rauwolscine enhances the fat-burning potential of the other ingredients included in Oxy Max XT.

  • Capsicum Annuum

    More often than not, you’ve seen pepper extracts listed as capsaicin in fat burners. Aside from their tongue-numbing effects, capsaicin has been shown to help with fat oxidation and thermogenesis.[17] Additionally, it also provides a nice release of adrenaline to give you a much needed energy boost.[17,18]..

  • Black Pepper Extract

    Also known as Piper nigrum, Black Pepper extract, when combined with other supplements, Several studies have found that black pepper extract, when combined with other supplements, increases the absorption and efficacy of the other ingredients. Having this valuable extract included as part of Oxy Max XT ensures you’ll reap all the fat-burning benefits it has to offer.

OxyMax XT

Dieting has never felt so good – We’ve used the new PEA ingredient (but not yet this product), and can say that it does feel fantastic!

Overall, this seems about as aggressive as you’re going to get without having any FDA-“banned” stimulants like AMP Citrate, which Performax Labs has wisely shelved. You get a combination of these effects:

  • The “feel” that everyone wants from the PEA compounds, and the hordenine to keep it around longer;
  • Hit Beta-2 fat burning angle from higenamine;
  • The Alpha-2 fat blocking angle from rauwolscine;
  • Thermogenesis / heat and other fat burning mechanisms from the red pepper extract;
  • The standard energy from caffeine;
  • …all potentially amplified by black pepper extract;

This is a formula with a diverse array of effects that we can expect to be around a lot longer, with the “feel” that so many people want, yet without the stimulants that will get one into trouble with the authorities.


Consume 1 capsule upon waking on an empty stomach. After assessing tolerance, an additional capsule can be taken 6-8 hours later. Sensitive users should consume with food. Do not exceed 3 capsules per day.

Wrap Up

As you can see, Oxy Max XT uses a LOT of ingredients, all disclosed behind a prop blend unfortunately. We’d really like to know the caffeine content on this guy, but we have a pretty good guess as to how much is contained within.

N-Phenethyl Dimethylamine continues to be the truly intriguing ingredient, and only time will tell if it really is a longer-lasting and more effective version of PEA.
