Serving size: 19 g
A pre‑workout powder delivering a high‑dose blend of citrulline, beta‑alanine, caffeine and supporting nootropics, sold in multiple flavours and pack sizes.
+ Strong nitric‑oxide and endurance support from 8 g L‑citrulline and 3.2 g beta‑alanine per serve. + Synergistic stimulant‑calm combo: caffeine paired with L‑theanine, L‑tyrosine and taurine for focused energy. + Zero calories and only 200 mg sodium per serve, making it low‑energy‑impact. + Fruit‑flavoured options include berry blast and passionfruit, a rarity in this segment. - Proprietary blend means exact ingredient amounts are undisclosed. - High stimulant load (300 mg caffeine plus other stimulants) may cause jitter‑iness in sensitive users. - Beta‑alanine and taurine share a transport pathway, potentially reducing absorption if taken together.
The PER4M Nutrition line stands out by pairing a full‑dose citrulline‑beta‑alanine base with a well‑balanced caffeine‑theanine‑tyrosine stack, offering both vascular and mental performance benefits uncommon in many pre‑workouts. While the fruit‑flavoured variants (both Bubblegum and Orange Mango) add berry blast and passionfruit for taste, the core formula remains identical and is positioned in a mid‑range price tier, with larger packs generally delivering better value. The proprietary blend limits full transparency, and the combined stimulant profile plus the beta‑alanine/taurine interaction warrant caution for those sensitive to caffeine or seeking maximal amino‑acid uptake.
