PEScience Prolific-1 Pre-Workout Review

PEScience Prolific-1 Pre-Workout has 53 ratings across the two stores (33 at PEScience and 20 at Vitacost), and the themes below come from the written reviews that could be read on their pages. Only four written reviews were readable on the PEScience page, alongside several customer questions, while the Vitacost page showed 20 short reviews dated December 2025 to February 2026. Every review discussed here is about the powder, and the page notes about other forms were not needed. Buyers most often praise the effect and the flavor. On the effect side, one reviewer describes full focus and a great pump every workout, and another reports clear energy with a great pump. A buyer says it gives a push without a tingle, which matches the page claim that Prolific-1 avoids the itchy skin many pre-workouts cause. A runner loves the orange flavor and says the product sits really well with her stomach, which she considers extremely important. Reviewers also credit the quality of the ingredients and call the brand reputable. Several say they buy it again, with one saying they keep coming back to it, and one first-time flavor buyer calls it a great pre-workout "as always," which suggests earlier PEScience purchases. One person likes that the package is not too big and fits easily in a gym bag. Flavor is the one area where opinion splits. Orange Cream was called not as sweet as one buyer expected but still really good. At Vitacost, the raspberry lemonade was said to taste like fruit juice rather than the extremely sour type, and the reviewer found it enjoyable. Another reviewer still ranks Sour Green Apple as their ultimate flavor, but puts this one in their top three. The clear negative is Guava Pineapple Punch: Karen S. did not think it was very good, called it kinda yucky, and says she keeps drinking it mainly because it was not cheap. That is the only comment touching on value, and it is tied to that flavor rather than to the product as a whole. On complaints, the Vitacost written reviews contain none about taste, mixing, side effects or value. The star breakdown there is 10 five-star, 6 four-star, 2 three-star, 2 two-star and no one-star ratings, so the lower ratings are not explained in the readable text. The product seems to suit people who want focus, energy and a pump without tingling or itching, and those with sensitive stomachs, such as runners. Questions on the PEScience page add practical points. The label warns against combining it with other caffeinated beverages, so one customer asked about using it with daily coffee, and PEScience suggested High Volume for coffee drinkers instead. Another asked about taking it together with High Volume, and PEScience said there is no need, as it is like combining Prolific with High Volume. Two customers asked about vegan status, and PEScience confirmed it is vegan friendly.
