How often did you have to give blood, which compound and what was the dosage and length. On one of my cycles I plan on using a gram a week of EQ, I've used it once at 400mg/week and liked it, I also found that on that cycle I needed to take a nap almost everyday but I never really got too tired or affected my workouts any. But with a gram I'm pretty sure it would get a lot worse and probably have to give blood to prevent from getting too tired or anything.
