I am running GW alongside s4 and lgd and my total cycle length is 16 weeks not 14 because I started s4 late. Going to stop lgd at week 12 and contonue s4 from week 4-16. If I am also running gw can i still run it into weeks 17-20 to help keep gains after cycle into pct? Will there be a loss of affect if kept at 20mg? Thanks!
