I've been reading more and more on these 4 week on/ off cycles, most interested in Test P with Anavar, dbol or tren.
But what I can't figure out is:

1. Seems a few go 4 weeks on, then 2-3 week PCT with a follow 2 week rest and then ON again. This seems hard to do any decent BW on.
Any comments on this?

2. What happends e.g. after the first 4 weeks and 4 weeks off, you want to suddenly do a 8 weeker, or change the compounds?
Is this possible or too much game with your body?

3. The stickies on this mainly talk abt the compounds used and pros/ cons of it in this short duration. Does anyone here have any experience with this and can tell their own experience?

Might have some more questions later but I highly appreciate any input. I Have a feeling that not many are familiar with this.
