MuscleForce Defiant Unleashed

(5 reviews) Write a Review


Defiant Unleashed is for the stim-junkies. The people who are tired of taking pre workouts that just don’t “Hit” anymore.  Here at MuscleForce we decided to create a product so potent we strongly recommend starting with only 1/2 scoop.

Why is it so effective?
We combined Eria Jarensis and 2-aminoisoheptane (DMHA). The combination of these 2 novel stimulants, provide a focused and energetic feeling that is nothing like you have experienced before. 
We gave you even more energy with Methylxanthine Anhydrous, Theobromine, & Octopamine HCL. To add on to the already incredible energy, we included Nootropics to help you focus even more, help you get a superior mind-to-muscle connection, and get your brain working on overdrive.To top it all off, the full doses of Beta-Alanine & Citrulline provide an endurance and pump boost to make this a complete, high-stim preworkout, that won't leave you behind asking for more.
Most of the time, these fully-loaded high-dosed pre-workouts only offer you 20 servings-or-so. We are giving you 30 FULL servings with Defiant Unleashed.
Experience the Force of Defiant Unleashed today. You won't want to go back to your old pre-workout after this.



As a dietary supplement, mix 1 scoop in 8-10oz of water 15-30 minutes before exercise. New users may start with 1/2 scoop to assess  their tolerance. Once your tolerance is assessed, dose accordingly. Do not exceed more than 1 scoop within a 24 hour period. For enhanced pumps, strength & enhance, stack DEFIANT with OBEDIENTX3 and/or CREA-GAINZ.

    Defiant Unleashed

    Absolutely solid. I’ve been doing this for a LONG time and this is one of the best pre’s I’ve come across. Carries me through my heaviest workouts with no crash.

    Best Pre Ever

    I have had my share of very high stim pre workouts, and this formula hits the perfect balance of high stim and caffeine but it does not make you crash. Quiet the opposite, it gives you a euphoric feeling after it processes through your system. Gives you great energy during the workout, laser focus, and it gently brings you down once your workout reaches its end. I take breaks from this pre on occasion and I always look forward to taking it as soon as my break is over. Cannot recommend this pre enough.

    Nothing Better!

    This has to be the best pre on the market with the crazy stimulant and hugely-dosed pump. Love it!

    Coming from someone who has a high caffeine tolerance and has trouble finding a pre workout that actually helps I highly suggest giving MF Defiant Unleashed a try! It keeps me going through those hard workouts and keeps me focused on UNLEASHING my full potential!
