Back when I competed, I ran test prop (100mg EOD) and winny (50mg-100mg EOD) before shows. I ran test for the entirety of the cycle (16 weeks). I'd toss the winny in at week 10 and run it until the end. I would start a running clenbuterol or ECA (or phen once) over the last month of prep. I tended to avoid then as much as possible though as they phuck with me. Tren is fantastic if you can tolerate it but I couldn't.
I also stacked 800mgs of primo but I didn't feel like it was worth the money and it was hard to find.
I had all of the ancillinary drugs too; Arimidex, hCG, Clomid and Nolva.
I usually finished up the cycle about five days out from the show as they were drug tested.
