Black Magic Supply | BZRK Overdrive | 40 Servings

Black Magic BZRK Overdrive is a fully disclosed hybrid pre-workout that leans into what experienced users actually want from a modern formula: meaningful pump support, moderate stimulant energy, cognitive drive, and a few foundational performance ingredients that reward consistent use. Rather than building the entire experience around an oversized stimulant hit, the formula distributes its weight across nitric oxide support, cell volumization, strength support, amino-driven performance, and mood-focus ingredients. That gives it a more complete identity than the average “energy first, everything else later” pre.

At the center of the pump side is 3,857mg L-Citrulline per scoop, or roughly 7.7g at the 2-scoop serving. That matters. Research on citrulline commonly lands in the 3-8g/day range, and this full serving places BZRK Overdrive directly in the clinically relevant zone for nitric oxide support and blood flow. Citrulline raises arginine levels more effectively than oral arginine itself, feeding the arginine-NO pathway and supporting vasodilation, muscle perfusion, and the fuller training feel most users notice in higher-volume work. Nitrosigine at 750mg per scoop becomes 1.5g at two scoops, which is the clinically studied dose for inositol-stabilized arginine silicate. That adds a second highly credible NO-support ingredient and helps differentiate this formula from basic citrulline-only pre-workouts.

The hydration and fullness side is anchored by GlycerPump at 1,285.5mg per scoop, or 2.57g at two scoops. As a 65% glycerol powder, that yields meaningful glycerol delivery for intracellular water retention and the round, dense muscle look users chase on pump-focused training days. Agmatine sulfate at 428.5mg per scoop, or 857mg at two scoops, rounds out the pump system by supporting nitric oxide signaling and neuromodulatory effects, though it sits below the 1g level many aggressive pump formulas aim for.

On the performance side, creatine monohydrate is dosed at 2,143mg per scoop, giving 4.286g at the full serving. That is a strong daily dose and close to the classic 3-5g range used to improve phosphocreatine availability, ATP regeneration, strength output, and repeated high-intensity performance. Betaine anhydrous lands at 1,071.5mg per scoop, or 2.14g full serving, which is right around the 2.5g benchmark commonly used in performance literature and still clearly meaningful. The BCAA trio is unusually targeted: 1g leucine plus 500mg isoleucine and 500mg valine per scoop, doubling to a 2:1:1 4g total BCAA serving at two scoops. This is not enough to replace a proper protein feeding, but it can support training-state amino availability and adds to the “performance amino” identity of the product.

The focus and mood profile is more interesting than average. L-Tyrosine at 643mg per scoop, or 1.286g full serving, sits in a practical range for catecholamine support under training stress. Kanna at 214.5mg per scoop, or 429mg full serving, is a notable inclusion for mood elevation and smoothening the stimulant feel. Lion's mane fruiting body at 200mg per scoop, or 400mg full serving, adds a nootropic-adjacent layer, though it is better viewed as supportive than standalone at this dose. The vitamin panel is not here to make this a multivitamin; it is a broad-spectrum support layer using active or useful forms like P-5-P for B6 and methylcobalamin for B12.

Synergy is where BZRK Overdrive makes the most sense. Citrulline, Nitrosigine, GlycerPump, and agmatine create a multi-angle pump system: nitric oxide generation, vascular support, and intracellular hydration. Creatine and betaine support output while improved blood flow potentially enhances nutrient delivery. Tyrosine, kanna, lion's mane, and the moderate stimulant profile are designed to produce focused training energy instead of frantic overstimulation.

Transparency is a real strength here. There are no proprietary blends, and every meaningful ingredient is disclosed with its exact amount. In a category still full of hidden-dose formulas, that lets you evaluate the label honestly. Day 1, expect noticeable energy, better pumps, and a smoother headspace than a pure stim bomb. After 2-4 weeks of consistent use, the creatine and betaine become more relevant, training performance feels more repeatable, and the formula’s “complete pre” design shows its value.
