i think ret took near 100mg or more ed and had no sides. me i took 25mg ed and got mad headaches from russians and bp skyrocketed for a long time. it was easier on lipids and cholesterol than tbol or var though. i tried 50mg ed in the beginnining and i got dizzy as all hell and hated the feeling. 25mg i felt great but head hurt bad, if i did it again i'd do it with small dose of letro and combat the water retention that causes the bp rise and headaches. it made me feel on top of the world
