A pre-workout is one of the essential supplements you should have in your arsenal. They provide an increase in energy, increased strength, better mental focus, more aggression, a better pump, and more productive workouts.

For those days when you have a huge session, or you’re lacking the energy or motivation, pre-workouts are a goldmine that will help you achieve your goals. RP Max CNS Thermo pre-workout and PSI are high quality pre-workouts that allow you to work harder by increasing your energy and motivation, reducing fatigue, faster recovery, and also give you a great pump. The combination of ingredients has been scientifically selected to work synergistically to boost energy and performance.

RP Max is a stimulant based pre-workout that provides optimal central nervous system and adrenal gland stimulation to trigger a positive homeostatic energy release, improved cognitive ability, muscular and cardiovascular endurance.

PSI is a non-stimulatory pre-workout that works to promote vasodilation, enhance nutrient and oxygen delivery to working muscle and improve muscle cell hydration and volumization. Vasodilation is where your blood vessels expand, or dilate to allow more blood flow; as blood carries nutrients and oxygen around your body, you get an increase in nutrient and oxygen delivery along with blood flow to working muscles. You should find you can perform better while also exercising harder and longer after using PSI or RPM.

Please refer to the individual product pages for Nutritional Info.

RP Max pre-workout and PSI pre-workout both have a different purpose and contribute in a unique way to enhancing your performance.

RP Max – Take 1 scoop of RP Max with 8-10 oz (240-295 mL) water 15-20 minutes before your workout. To get the most benefit out of RP Max, we recommend that you only use it on training days and not within 5 hours of going to sleep due to its stimulant-based nature. This makes RP Max an optimal addition to morning and lunchtime workouts.

PSI – Take 1 scoop of PSI with 8-10 oz (240-295 mL) water 20 minutes before your workout. As PSI is not stimulant based, it should be used in the place of RP Max if training later in the day or at night (less than 5 hours before going to sleep).

Stacking – PSI can be stacked with RP Max so that you gain all the benefits of the stimulants and fat burner thermogenics from RP Max along with the increased blood flow benefits from PSI’s vasodilation nutrient delivery system, contributing to a highly energetic, focussed workout along with an increase in muscle volumization and pump. This combination should only be used in the morning or for lunchtime workouts due to its stimulant-based nature.

Do not exceed 1 scoop of each per day.
