Dark Labs | Maniaco | 20 Servings

Dark Labs Maniaco is a fully disclosed, high-stimulant pre-workout built around two clear objectives: drive a real pump with a legitimately large citrulline dose, and pair it with an aggressive central nervous system stimulant stack designed for experienced users only. This is not a “balanced everyday pre.” It is a formula for hard sessions, built with a clinical-performance backbone up front and a hardcore stim profile layered over it.

The performance foundation starts with 10,000mg L-citrulline, which is a standout dose. Citrulline raises plasma arginine more effectively than oral arginine itself because it bypasses significant intestinal and hepatic metabolism before being converted in the kidneys. That matters because arginine is the substrate for nitric oxide synthesis, and nitric oxide is what drives vasodilation, blood flow, nutrient delivery, and the skin-splitting pump users chase in the gym. Research and meta-analytic data support citrulline as a meaningful nitric oxide precursor, with common performance-focused dosing often landing in the 3-8g range. Maniaco goes beyond that typical range with a full 10g, which positions it well above the underdosed 3-6g category norm.

L-tyrosine is included at 4,000mg, which is a very large dose in a pre-workout context. Tyrosine is the amino acid precursor for catecholamines like dopamine and norepinephrine. Under high stress, sleep deprivation, or intense training, providing more substrate for catecholamine synthesis can support focus, composure, and mental output. Human evidence is mixed depending on context, but mechanistically the inclusion makes sense here because caffeine and DMHA both increase stimulant pressure on catecholamine systems. Tyrosine helps support that demand.

Beta-alanine is dosed at 3,200mg, the classic daily research-backed amount for building intramuscular carnosine over time. Carnosine buffers hydrogen ions that accumulate during repeated high-intensity work, which is why beta-alanine is less about instant strength and more about delaying the burning fatigue that shows up in longer sets, supersets, machine finishers, and repeated intervals. This is one of the strongest decisions in the formula because it matches the dose most commonly used for saturation.

The stimulant complex is what defines Maniaco’s personality. Caffeine anhydrous at 400mg is already a high-end dose capable of significantly increasing alertness, training intensity, and perceived energy. On top of that, the formula adds 300mg 2-aminoisoheptane (DMHA), 300mg N-phenethyldimethylamine citrate, and 2mg Rauwolfia vomitoria extract standardized to a minimum 90% alpha yohimbine. Mechanistically, this stack is designed to intensify CNS drive, mood, urgency, and appetite suppression, while alpha yohimbine adds a sharp thermogenic edge. It is also the part of the formula that warrants honesty: DMHA has limited human safety data for oral sports supplement use, and this is a very aggressive total stim profile. This product is clearly intended for advanced users with high tolerance, not beginners.

The synergy is deliberate. Citrulline helps preserve blood flow and pump in a formula otherwise loaded with stimulants that can feel vasoconstrictive. Tyrosine supplies catecholamine precursor support while caffeine, DMHA, and Eria-style phenethylamine compounds create the high-energy, high-focus training experience. Beta-alanine rounds it out by supporting repeated-effort endurance rather than just the first 20 minutes of stimulation.

Transparency is a real strength here: no proprietary blend, no hidden stimulant matrix, no guessing. Every major active and its dose are disclosed. Day 1, expect a strong onset, pronounced stimulation, tingling from beta-alanine, and noticeable pump support if hydration is in place. Across 2-4 weeks of regular use, the biggest cumulative change comes from beta-alanine as muscle carnosine rises and hard sets become more repeatable before fatigue forces you to shut them down.
