Serving size: 9 g
Optimum Nutrition pre‑workout powder delivers a stimulant‑rich blend of caffeine, beta‑alanine, taurine and a full spectrum of essential amino acids per serving.
+ High dose of BCAA (2 g) and added L‑Glutamine for muscle support. + Includes 100 mg caffeine plus natural caffeine (in some flavours) for a noticeable energy boost. + Vitamin C (24 mg) pairs with L‑Arginine, offering a modest nitric‑oxide supporting synergy. + Green Tea Extract present in all variants; Pineapple flavour also adds Green Coffee Bean Extract and L‑ascorbic acid, rare among peers.
- Combined stimulants (caffeine with beta‑alanine, taurine or L‑Tyrosine) can increase jitteriness or anxiety in sensitive users. - Beta‑alanine and taurine share a transport pathway, potentially reducing absorption if taken together. - Contains soy lecithin, soya and artificial sweeteners (sucralose, acesulfame K).
All variants share the same disclosed ingredient doses and core nutrient profile, with only minor flavour‑specific additions such as natural caffeine, green coffee bean extract and L‑ascorbic acid in the Pineapple version. Larger packs tend to provide better value, while the budget‑tier Fruit Fusion is positioned at the lower price point. The formulation’s blend of stimulants and amino acids is designed for high‑intensity workouts, but the synergistic stimulant mix may be too intense for those sensitive to caffeine or prone to overstimulation.
