your pct should be similar to this, some people do run slightly less than this.
Day 1 - 100mg
Following 10 days - 60mg
Following 10 days - 40mg
as for the nolva throughout, i just keep it on hand and use it at 20mg if a slight sign of gyno. some others may advise you to use throughout if you suffer badly from gyno. i think its just wasting money,
