Reorder & review

Over 90% of Medibro subscribers are still on the same product at 3 months — the clearest signal a supplement is working.

BCAAs (leucine, isoleucine, valine) make up approximately 35% of muscle protein. Leucine specifically activates mTOR — the key signal for muscle protein synthesis. Supplementing BCAAs during training can reduce muscle breakdown and improve recovery.

Our 2:1:1 ratio (3.5g leucine, 1.75g isoleucine, 1.75g valine) matches the most commonly studied ratio.

    Correct 2:1:1 ratio

    06/02/2026
    Reduced my DOMS significantly

    Since adding BCAAs intra-workout, delayed onset muscle soreness is much less severe. Can train legs more frequently which has accelerated my progress. Good product.

  • ★★★★☆Marcus T.
    16/01/2026
    Good value, effective ratio

    2:1:1 is the correct leucine:isoleucine:valine ratio used in studies. Other brands use 4:1:1 but the research doesn't support higher leucine ratios being better. This is properly formulated.

  • ★★★★★Dan L.Verified buyer
    04/12/2025
    Mixes perfectly, no clumping

    The instantised version dissolves in cold water without shaking for 5 minutes like non-instantised BCAAs. Tastes clean, no chemical aftertaste. Takes intra-workout and recovery feels better.

  • ★★★★★Jade P.Verified buyer
    02/12/2025
    Essential for fasted training

    Training fasted in the mornings. BCAAs prevent muscle breakdown during the fast. Energy during workouts improved and I'm not sacrificing muscle. Good quality.
