any of you guys ever try tribulos, arginine, whey protein, glutamine, ZMA or eating healthy? ive been working out with weights and doing PE and i noticed when i started my two day split, six days a week, my labido went down to nothing, so i figured my testosterone must've been drained. ive been taking 625mg of tribulos a day, 4 grams of arginine, 10 grams of glutamine, and making sure i get around 200grams of protein per day and i dont know if im imaginine things but it seems that the tribulos and arginine which i just recently added to my supplements has restored my libido, and my penis isnt soar for nearly as long when i do my jelq and streches. pretty soon i'll get my zma from amazon in the mail and its sopost to help recovery when one sleeps. anybody got personal exerience with these supplements? side effects?
