Black Mirror is a pre‑workout supplement made by Muscle Add.
It’s marketed as an “ultra‑concentrated” pre‑workout formula aiming for “explosive energy, pump, focus, and endurance.”
Available in powder form (commonly 270 g / 254 g tubs, delivering around 30 servings) and also — in some places — a “single‑serve” version (9 g / 1 serving).
According to the product info, each serving of Black Mirror includes roughly:
| Ingredient / Component | Approximate Dose per Serving | Purpose / Effect |
|---|---|---|
| Beta‑Alanine | ~ 2400 mg | Helps buffer lactic acid — can reduce fatigue during intense training and support endurance. |
| Arginine (as AAKG / arginine‑based) | ~ 1500 mg | Supports nitric oxide production → improved blood flow / “pump,” better nutrient & oxygen delivery to muscles. |
| Creatine HCl | ~ 1500 mg (or a lower listed 225 mg depending on source) | Aims to support strength and power output, and help with performance under load. |
| Caffeine | ~ 220–222 mg | Provides stimulant effect — energy, alertness, improved focus before/during workouts. |
| Vitamins / Misc components | B‑vitamins and others (depending on batch) | Support general metabolism, energy production. |
Usage instructions (typical): Mix 1 scoop with ~200–300 ml cold water, 15–30 minutes before training. Do not exceed 2 servings per 24 hours.
According to sellers and product descriptions, Black Mirror aims to deliver:
Strong energy and focus — thanks to caffeine + stimulant blend.
Enhanced “pump” / better blood flow / vascularity — via arginine, nitric‑oxide boost.
Improved strength & performance potential — creatine + endurance mixture aims to help during heavy lifts / intense sessions.
Reduced fatigue & better endurance — beta‑alanine helps buffer lactic acid, potentially allowing more reps/longer sessions.
Mental alertness & focus during training — caffeine + supportive compounds for clarity and drive.
Because of this mix, Black Mirror is often marketed toward people wanting a “hardcore” pre‑workout boost — heavy lifting, bodybuilding, or high‑intensity training sessions.
As with many pre‑workouts: due to stimulant and active ingredients (caffeine, etc.), it’s not suitable for minors, pregnant or breastfeeding people, or those with heart / blood pressure / health conditions.
Because of strong formula, if you’re a beginner or sensitive to stimulants — it may be wise to start with half a scoop to assess tolerance.
Supplements are not a substitute for proper nutrition, diet, hydration, rest; benefits still depend on overall training, food, recovery.
