Serving size: 11 g
Pre‑Workout powder delivering a comprehensive blend of creatine, beta‑alanine, caffeine, L‑citrulline and other performance‑supporting nutrients in a single serving.
+ Broad spectrum of ergogenic ingredients (creatine, beta‑alanine, caffeine, L‑citrulline, L‑tyrosine) commonly used for strength, endurance and focus. + Certified by Informed Sport and Informed Choice, indicating third‑party testing for banned substances. + Includes natural caffeine and flavoring, which are uncommon among many pre‑workout peers. + Larger pack sizes tend to offer better value within the range.
- Proprietary blend means exact ingredient amounts are undisclosed, limiting dose transparency. - Contains multiple allergens (eggs, gluten, milk, peanuts, soya, tree nuts), which may restrict suitability for some users. - The creatine‑caffeine interaction is noted as antagonistic, potentially reducing creatine’s efficacy if taken together.
All variants share the same core formulation, delivering a high‑dose mix of creatine (≈3 g), beta‑alanine (≈1.5 g), caffeine (≈175 mg) and L‑citrulline (≈750 mg) per serving, along with a suite of B‑vitamins and other actives. The blend is marketed as a “Gold Standard” pre‑workout and is produced in GMP‑registered facilities that report compliance with cGMP, Informed Sport, Informed Choice and BRC standards. While the base formula is consistent, some flavours add specific flavoring agents and natural caffeine, a rarity in this category. Users should note the proprietary nature of the blend, the presence of several common allergens, and the potential antagonism between creatine and caffeine when timing doses.
