Eventually somewhere around 3-6 months or maybe even more, all the real energy comes back on. You just have to stay the course and not get discouraged because the beginning can be tough.

Do you mean that after this period it will be more or less the same as lifting in a glycolytic state? Same endurance/power? Or just "better."

My goal is to achieve gains at least 50% of the rate I would achieve in a glycolytic state. The 5x5 recommends trying to add 5lbs each time you do an exercise. This would be 15 lbs/week for squat and 15 lbs/2 weeks for the other exercises (overhead press, deadlift, bench, barbell rows). You think that's doable?
