One of my friends in FL. IS Taking, all kind of supplements, but my question is he's taking about 1500 mgs of tribulus a day but he takes them all at once in the morning, should he split it through out the day ?? He is not doing any AS, And is getting great results.. He has been taking it for about a year, then another friend of mine says that tribulus can cause kidney stones, is this true ?? Now one question for me, im 7 weeks into cycle of test cyp 300mg's twice a week, and my sex drive has crashed, but still seeing good gains, can i add tribulas into my cycle now or wait for pct, im doing a 14 week cycle..And on lions site what is the best brand.. Thanks guys..
