Afterdark | Inhuman Pyro | 21 Servings

Afterdark Inhuman Pyro is a true thermogenic pre-workout, not a standard pre with a token “fat-burning” add-on. The formulation strategy is clear: maintain enough performance support to keep training quality high, then layer in a serious stimulant and thermogenic system designed to raise intensity, heat, alertness, and perceived drive. That makes this formula most relevant for experienced users in a cut, recomp, or high-output training phase who still want pump, endurance support, and focus instead of relying on raw stimulants alone.

The performance backbone starts with 5,000mg L-citrulline. Research most often supports 6-8g for fully clinical nitric oxide support, so 5g is slightly below the textbook sweet spot, but still absolutely functional. Citrulline converts to arginine in the kidneys more efficiently than oral arginine itself, increasing nitric oxide production for vasodilation while also supporting ammonia clearance through the urea cycle. In practice, that means better blood flow, better training feel, and less of the flat, drained sensation that many cutting pre-workouts create.

Beta-alanine is dosed at 3,500mg, which is within the effective daily loading range and above the classic 3.2g benchmark used in sports nutrition. Its value is cumulative, not just acute: beta-alanine raises intramuscular carnosine, and carnosine buffers hydrogen ions generated during hard training. That is why the burn feels delayed after consistent use, especially in repeated high-rep sets, circuits, and short-rest hypertrophy work.

The energy system is intentionally aggressive. Total caffeine is verified at 375mg, delivered through caffeine anhydrous, dicaffeine malate, and micro-encapsulated caffeine. That combination matters: anhydrous caffeine gives the rapid onset, dicaffeine malate can smooth part of the curve, and micro-encapsulated caffeine helps extend the experience beyond the fast spike-and-drop profile of single-source stimulant formulas. Theobromine HCl at 200mg complements this with a longer, smoother methylxanthine lift that tends to feel more sustained and less abrupt than simply adding more caffeine.

The focus stack is respectable, though not elite. Fermented L-tyrosine at 1,000mg supports catecholamine synthesis under stress, which is exactly when pre-workout users need it most. Choline bitartrate at 500mg and DMAE bitartrate at 500mg are included for acetylcholine-related focus and mind-muscle connection support, though this is not as premium a choline strategy as Alpha-GPC or CDP-choline. NeuroRush™ at 100mg lands right in the researched 100-150mg range and adds coffee-derived polyphenols for cognitive fatigue support without depending entirely on more stimulants. L-theanine is present at only 35mg, which is well below the common calming range used to smooth high caffeine loads, so this formula is not designed to feel mellow.

The thermogenic stack is where Inhuman Pyro makes its identity unmistakable. CapsiBurn™ at 100mg is right at the target dose and activates TRPV1 pathways via capsaicinoids to increase catecholamine output, heat, and energy expenditure, with a delivery system designed to reduce the GI harshness that standard capsaicin can cause. CaloriBurn GP™ at 25mg is a clinically relevant grains of paradise extract standardized for 6-paradol, a compound linked to thermogenesis and brown adipose tissue activation. ProGBB™ at 25mg is also in the studied range and is well known for producing a pronounced sweating response by increasing the carnitine pool through gamma-butyrobetaine metabolism. Chromium at 500mcg as nicotinate glycinate chelate sits comfortably within the 200-1000mcg research range and supports insulin signaling and glucose handling, which is more useful for nutrient partitioning and metabolic support than for a dramatic body composition effect on its own. Vitamin B12 at 500mcg as methylcobalamin supports general energy metabolism, especially in individuals with lower baseline status.

Transparency is mixed. Most headline ingredients are fully disclosed and dosed clearly, which is a major plus in this category. However, the caffeine sources are listed without individual source amounts, so while total caffeine is known, the exact internal breakdown of the delayed-release stimulant matrix is not. That is more transparent than a fully hidden proprietary blend, but less transparent than a completely open-label formula.

What to expect: day 1 is about onset, heat, alertness, appetite suppression carryover, beta-alanine tingles, and a hard-driving training feel. Weeks 2-4 are where the formula improves meaningfully through beta-alanine loading, more predictable tolerance to the stimulant profile, and better repeat-set performance from higher muscle carnosine. This is a high-stim thermogenic pre-workout with real performance support, but the personality of the formula is unmistakably aggressive.
