Agreed JJ. There are MANY things that can cause fluid retention, including excess heat or cold, high altitude, dehydration, excess estrogen or progesterone, 'stress', insulin resistance/high carb intakes, alcohol, mineral imbalances, obesity, etc.....to suggest that only people on AAS have issues with fluid retention is silly.
That herbal concoction you use is VERY similar to the one I use precompetition. Works well, but I take 6 times the recommended dose!
