If you've been disappointed by so-called straightforward preworkouts that promise big doses but leave you listless, think again. Already in elite company with it's per-scoop/per-serving doses (37g at full dose!), Relentless wastes little time transitioning from performance/pump (10g citrulline, 5g betaine, 5g beta-alanine) into energy and focus. Dual choline sources (DMAE and Alpha-GPC) pair well with 2g L-Tyrosine for resistance to stress and optimal neurotransmitter levels, which your body will translate for you into both higher peak power output and sustained power output overtime. Then, the energy. Caffeine meets Dynamine meets Theobromine, all three of which are propelled forth by EnXtra's unique ability to improve attention sorting and magnify the effects of stimulants coingested with it. The result of this synthesis is a clean-burning, anxiety-free rocket ride that you can scale up to your own preference: 1 scoop, 1.5 scoops, or 2 scoops, as needed. Dynamine turns the lights on right away while being more dopaminergic than caffeine, and Theobromine offers alertness and circulation without increased heart rate or blood pressure. In short: Relentless will allow you to train in the fashion after which it was named.
