Basically winnie will increase strength because it is an androgen, like test and tren. Androgens cause a significant increase in motor units and neural connections and significantly increase your brains ability to recruit the most muscle fibers for a given task. Also androgens can shift the sodium potassium ratios in favor of water retention, which will increase strength. Lastly they will also increase aggression, which will make you more focused and energized in the gym. O and lets not forget nitrogen retention or cortisol inhibtion either...These are a few ways androgens increase strength, but there are others as well as ones we dont even know about yet...
