PEScience Prolific is a Sour Peach Candy pre-workout powder designed to support workout energy, focus, pumps and endurance, with 40 servings per container.
Prolific is made for people who want energy, concentration and pump support as part of a pre-workout routine. Its formula brings together caffeine, nootropics and workout-focused ingredients in one powder, with a Sour Peach Candy flavor. The product is positioned for both men and women, and the ingredients are chosen to address several training priorities in one formula rather than focusing on energy alone.
Two caffeine sources paired with L-theanine are intended to provide sustained energy without harsh jitters or a post-workout crash. For concentration, the formula uses Cognizin Citicoline, a form of CDP choline, alongside Rhodiola. These ingredients give Prolific an energy-and-focus profile for training sessions where staying attentive rep after rep matters.
The formula’s focus ingredients are nootropics, while its caffeine blend addresses workout energy. This combination is intended to support concentration and the mind-muscle connection during a session. Prolific’s energy portion is also designed to act quickly while maintaining a smoother feel through the workout.
A 2-scoop serving provides 6 g of pure L-citrulline, rather than the citrulline malate form. Prolific pairs citrulline with betaine and taurine, ingredients included to support muscle pumps, performance and endurance. This combination makes the formula relevant to people looking for pump support alongside pre-workout energy and focus.
The citrulline amount is provided for the full 2-scoop serving, so that serving detail matters when comparing formulas. Prolific’s pump component is built around L-citrulline, while betaine and taurine round out the performance-focused ingredients. Together, these ingredients are intended to support blood flow, muscle fullness and the ability to keep working through a session.
No. Prolific contains neither beta alanine nor creatine. Leaving out beta alanine is a key formula distinction for people who prefer to avoid the skin tingling associated with that ingredient; the product is designed to provide its energy, focus and pump support without it.
This makes Prolific a choice for shoppers seeking a multi-part pre-workout formula that does not rely on either ingredient. The formula’s listed performance components instead include caffeine, L-theanine, nootropics, L-citrulline, betaine and taurine. Its intended use is pre-workout support, with the ingredients focused on workout energy, concentration, pumps and endurance.
PEScience Prolific suits trainees who want a flavored pre-workout powder combining energy, focus and pump support, including people looking for a formula without beta alanine or creatine. Its 40-serving container comes in Sour Peach Candy flavor and brings those workout-focused ingredients together in one product.
