from the info I read out there it say the igf should only be used 4-5 weeks max with a 20-30 day break,because the effect from igf if done by 50 days ,so asking other people on the forum some go on for 3-6 months straight ,I just want to know if I do 2 bottles back to back for 100 days will I be wasting my igf or should I do a 20-30 day break in between ? info please on people that went on it longer then 50 days.......
