"The Stack" is usually run as a bridge I believe... seen it advertised like that, PP into SD.
that's crazy high doses, 70mg of harsh methyls for 4 weeks. Superdrol does not need to be run at 30, especially from day 1, and PP should start lower.
This is a better idea:
It's still a 5 weeker with 2 weeks of overlap, it's MORE than enough. IMO it's better to stretch it out a little longer than to stack two of the most powerful compounds so heavily for 4 weeks. Unnecessary sides!
