Transparent Labs Stim-Free is a broad caffeine-free pre-workout with 8 grams of citrulline malate, 4 grams of beta-alanine, betaine, taurine, tyrosine, and branded performance ingredients. It suits late training and stimulant breaks, but the large scoop is not for everyone.
Many stimulant-free pre-workouts stop at pumps. This formula combines citrulline malate with beta-alanine, betaine, taurine, tyrosine, SenActiv, elevATP, BioPerine, and Huperzine-A.
That gives it broader performance coverage, but also makes the serving larger and more complex than a simple citrulline or nitrate powder.
I used an earlier Stim-Free formula several times. The scoop was large, but I felt focused during training and the focus carried into the hours afterward. I barely noticed the beta-alanine tingles because I was already accustomed to it.
The current formula is materially different, so those notes remain historical rather than a current-formula test.
Take one current labeled serving before training. First-time users should assess it alone before stacking more beta-alanine, betaine, or Huperzine-A.
Stim-Free is worth considering when you want a complete caffeine-free training formula rather than a pump-only product. It covers more performance categories than most minimalist non-stims.
The trade-off is complexity: a large scoop, high beta-alanine dose, and Huperzine-A. Choose it for broad performance coverage, not simplicity.
