I ran this for 2 weeks straight at 500 mcg Ed. When I did this I also increased my cals pretty substantially. Was eating at least 2 normal jars of peanut butter a week with whatever random snacks I found. All healthy snacks tho lol got them from the organic section in Kroger to see if I could get away with it. Anyway the methy tren worked very well veins still stayed ver prominent at times even above average and strength was deff there. I didn't really notice and any aggression sides... Maybe slightly but I was also dealing with things from word so I lil of from that already. Overall good product and would deff use this stuff again! Thx
