i am in the process of beginning a new cycle consisting of the following:

1-4 wk d-bol 30mg daily
1-8 wk tren 100mg ED
1-10 wk andropen 825mg wkly.

for pct i was going to run clen /nolvadex , yet often i see people add nolvadex into their entie cycle.why is this?is it for the same reason you run it PCT, just with the benefits of it throughout the cycle?thanks for the help.
