Performax | OXY is a high-stimulant thermogenic capsule built for fast energy, hard-hitting focus, and noticeable heat production. It fully discloses every active instead of hiding behind a proprietary blend, with about 256mg total caffeine per capsule.

OXY is built around energy, thermogenesis, and focus—not phosphocreatine saturation. Adding a standalone creatine monohydrate fills that gap by supporting ATP regeneration, strength retention, and training quality while dieting, all without increasing stimulant load.
Any time daily; can be taken alongside OXY or with a meal
A high-stim fat burner helps you train harder during a cut, but preserving muscle still depends on protein intake. Pairing OXY with a high-quality protein supports recovery, satiety, and lean-mass retention while the thermogenic stack supports calorie expenditure.
Post-workout or anytime protein intake is low
Formulas containing caffeine, Paradoxine®, ProGBB™, and rauwolscine can increase sweating and make sessions feel hotter. An electrolyte product helps maintain hydration quality, muscular function, and workout output during longer cardio sessions or aggressive cuts.
Before, during, or after training with OXY
Because OXY already covers the stimulant side aggressively, the best stack is often a non-stim performance product that adds citrulline, nitrates, glycerol, or taurine without pushing caffeine higher. This lets you combine fat-burning intensity with better blood flow, endurance, and training quality.
20-30 minutes pre-workout with OXY
A serious thermogenic only works well if recovery stays intact. If you're using OXY earlier in the day during a calorie deficit, a separate evening recovery or sleep-support product can help protect sleep quality, which is critical for appetite regulation, training recovery, and body-composition progress.
Use at night, well separated from OXY
OXY is the better pick when you want a dedicated thermogenic capsule instead of a full pre-workout.
Sear has the edge for stimulant-sensitive users or anyone needing a non-stim cutting option.
OXY is more aggressive and more transparent for experienced users wanting stronger stimulation.
Both target fat loss, but OXY leans harsher and hotter while Burn2O is broader-market.

Performax | OXY is a high-stimulant thermogenic capsule designed around one clear formulation strategy: create a fast-onset, hard-hitting fat-loss experience without relying on a proprietary blend. Instead of hiding behind vague “energy matrix” language, this formula discloses each active and shows you exactly where the formulator chose to push intensity—namely stimulant-driven focus and output, layered thermogenesis, and several ingredients aimed at increasing the amount of energy your body dissipates as heat.
The central stimulant backbone is 200mg caffeine anhydrous plus 75mg Infinergy® dicaffeine malate. Because Infinergy® yields roughly 73% caffeine, the total caffeine exposure lands at about 255-256mg per capsule. That is a serious single-capsule dose. The anhydrous caffeine gives the fast rise in alertness, training drive, and thermogenesis you feel early, while the dicaffeine malate is intended to buffer and extend the energy curve so the product feels less like an immediate spike-and-drop formula. This is a smarter stimulant architecture than using one caffeine source alone.
Focus and mood are amplified by NeuroPEA™ at 200mg and ThinFen™ at 100mg. In this context, NeuroPEA™ refers to the Eria Jarensis category used in sports nutrition, not palmitoylethanolamide. The goal is elevated dopamine/noradrenaline tone and a pronounced sense of urgency, motivation, and tunnel vision. At 200mg, NeuroPEA™ sits in the common effective range used in high-stim products. ThinFen™, a hydrochloride form of phenylethylamine, is also right in the useful 100-250mg range. PEA-type compounds are known for fast, noticeable mood lift and transient focus enhancement, though the human clinical literature is more limited than it is for caffeine. In real-world use, these are the ingredients that often make a thermogenic feel “on” rather than merely caffeinated.
The thermogenic layer is where OXY becomes more interesting. Paradoxine® at 40mg is a full clinical dose of grains of paradise standardized to 6-paradol. Its mechanism is not just general stimulation; it is specifically linked to brown adipose tissue thermogenesis via TRPV1 activation and UCP-1 upregulation. Fucoxanthin at 8mg is also notably well-dosed, sitting at the top of the researched human range. It works through a different but complementary route by promoting UCP1 expression and encouraging a “fat browning” effect. That means this formula does not depend exclusively on stimulants to create a metabolic effect.
Citrus aurantium at 25mg and Rauwolfia vomitoria extract at 2mg standardized to 90% rauwolscine add a more aggressive adrenergic edge. Synephrine and rauwolscine are common inclusions in advanced thermogenics because they can intensify lipolysis and create that unmistakable “cutting phase” feel, especially around cardio. Cocobuterol® at 50mg adds another layer through cocoa alkaloids and flavanol-rich support tied to beta-2 signaling, blood flow, and cAMP activity. ProGBB™ at 20mg is slightly below the 25-50mg range commonly discussed for stronger standalone thermogenic effects, but it remains directionally useful as a carnitine-precursor ingredient associated with increased sweating and enhanced fatty acid transport. Expect it to contribute more as part of the system than as a headlining dose on its own.
The synergy is deliberate: fast and sustained caffeine for energy, NeuroPEA™ and ThinFen™ for mood-forward CNS intensity, synephrine and rauwolscine for adrenergic fat-loss pressure, and Paradoxine® plus fucoxanthin for non-redundant thermogenic support through uncoupling and brown fat activation pathways. Transparency is a real strength here—no proprietary blends, no hidden milligrams, no guessing. Day 1, most users will notice a sharp rise in alertness, warmth, and training urgency. Over 2-4 weeks, the ingredients most tied to cumulative body-composition support are Paradoxine® and fucoxanthin, especially when paired with a calorie deficit, consistent training, and cardio.
OXY uses two caffeine forms to shape both onset and duration. Caffeine anhydrous is rapidly absorbed and produces a quicker rise in central nervous system stimulation, while dicaffeine malate tends to extend the tail of the energy curve. Mechanistically, caffeine antagonizes adenosine receptors, increasing neuronal firing, catecholamine signaling, and perceived readiness to train. In a thermogenic context, that same stimulation also raises work output and can support greater total daily energy expenditure.
Paradoxine® and fucoxanthin are often discussed through the lens of thermogenic uncoupling and brown adipose tissue activity. Grains of paradise has been studied for increasing energy expenditure and heat production, likely through transient receptor potential signaling and sympathetic activation. Fucoxanthin is mechanistically linked to UCP1-related effects in adipose tissue, which may promote greater energy dissipation as heat. These pathways are not magic fat loss switches, but they can complement a calorie deficit by modestly shifting expenditure upward.
NeuroPEA™ and ThinFen™ are included to intensify the subjective experience of motivation, focus, and central drive. Phenethylamine-class compounds are short-lived neuromodulators associated with catecholaminergic signaling, especially when paired with stimulants. In practice, this can feel less like generic energy and more like sharpened intent, elevated mood, and faster task engagement. That distinction matters during a diet, where mental fatigue often undermines adherence and training quality before physical capacity truly collapses.
A strong warming effect does not automatically equal dramatic fat loss, but it usually reflects real sympathetic and thermogenic activity. Ingredients such as cocobuterol, grains of paradise, citrus aurantium, and stimulant alkaloids can increase perceived heat, sweating, and metabolic urgency. The meaningful question is whether the formula also supports adherence, training output, and daily expenditure strongly enough to matter over time. OXY is built around exactly that strategy: make the cutting phase feel more energetic, more active, and easier to execute consistently.
