Pre‑Workout powder delivering a standard blend of L‑Citrulline, Beta‑Alanine, Taurine, L‑Tyrosine, Caffeine, Theobromine, African Mango, Grains of Paradise, Vitamin B3 and a bio‑enhancer, offered in several flavours and pack sizes.
+ All active doses are fully disclosed, giving clear transparency. + Combines L‑Citrulline with Beta‑Alanine and Caffeine, a synergistic trio shown to support blood flow, buffer lactic acid and boost alertness. + Includes a rare colourant (E122) and flavourings, a distinctive feature among pre‑workout peers. + Larger packs tend to provide better value within the budget tier.
- Multiple stimulants (Caffeine, Theobromine, Taurine) raise the risk of jitteriness or heart‑rate spikes in sensitive users. - Beta‑Alanine and Taurine share a cellular transporter, which can limit their absorption when taken together. - Contains sucralose and, where applicable, the red colourant E122, which may be undesirable for some consumers.
The Per4m range stands out for its fully disclosed, high‑dose blend that pairs nitric‑oxide support (L‑Citrulline) with classic endurance aids (Beta‑Alanine, Caffeine) and a unique visual touch via E122 colourant in each flavour. While the core formulation is identical across variants, the Blue Raspberry version swaps Piperine for Bioperine, and all flavours list colourant “where applicable”. Price tiers shift with pack size, with larger bottles generally offering the most economical option. Users should watch the combined stimulant load and the known competition between Beta‑Alanine and Taurine for optimal absorption.
