  2. Unexpectedly very potent and powerful pre-workout!

    Kaya Genc

    Was given a tub of Harness by MassiveJoes.com, and I’ve got to say, this pre-workout doesn’t disappoint. Lemon Rush isn’t a bad flavour – the focus on this is incredible, power output is quite good, pumps were actually quite good, and I had nice clean energy throughout (took 2 scoops). Good experience, I do recommend this pre for those who aim to get sh** done and lift some heavy-ass weight!

  4. My new go-to stim based pre workout!

    Cameron Gates (verified owner)

    After wanting to make a change from my previous pre-workout supplement, a fair amount of thought and independent research lead me to Harness by ARN and honestly, could not be more chuffed! It covers all the bases that you look for in a stim based pre-workout supp, stacks easily with any pump/focus based non-stim pre workouts and taste’s terrific to boot. I’ve tried the Bombsicle and Tart Candy Strings flavours and love them both, highly recommend!
