Hello everyone. A little background on me. I am a college triathlete so a large portion of my training is cardio. I lift a few times a week so I was using this pre for those sessions.

Ingredient Profile

I like to start this section by saying I'm in no way a professional nutritionist or scientist and speak from research, experience with the product, and experience with other pre-workouts.

Full SpectrumRX does a great job listing all of its ingredients with no prop blends. Nothing seems to be underdosed and the ingredients all work well together. This is a complete Pre-workout with a great list of ingredients.


This is the one category this product lacks in. The first thing I noticed was how large the scoop was. 1 serving is huge with 22.26 grams of powder in one scoop. Since there's so much powder per scoop it's hard to get the drink fully mixed. This is also one of the worst tasting pres I have tried. It's definitely one to down and forget about.


The first time I took this pre-workout I went through my normal lifting routine. It wasn't until I was showering after that I realized how effective this pre-workout is. I was still feeling the effects with a boost of energy and a feeling that I could conquer the world. I consistently felt the stims pumping me up and pushing me through the workouts and leaving me with energy to finish my day. Occasionally I'll end a lift with a long run. Once I got moving through the drink became more of a burden, feeling heavy in my stomach. I avoided the drink completely for purely cardio workouts based off of this. Overall though the benefits from the lift outweighed this slight bump and were easy to overcome by just not taking if a run is on the schedule.


While this product is on the more expensive side of pres you're paying for what you get. A container can be found for $50. The ingredients and effectiveness are worth the money. If you can find a deal or a way to get the price down a little bit then I would without a doubt recommend Full SpecteumRX.

Side Effects

With the power of the stims in this pre-workout, you might be left jittery. Careful not to take too close to bedtime or you may be up awhile too. Overall pretty common side effects for pre-workouts.


Once you get past the mixing and the taste this is one of the best pre-workouts I've had in a long time. Full SpectrunRX has made its way into my rotation of favorite supps and I look forward to trying another flavor in hopes of a better taste!!!
