i really think the guys that grow well on lots of test or did, could have grown on anything really. they will circle back to that as their reason for size, but prolly didn't try any other method.When I was younger (90s) and wanted to turn pro it would be like 2-400mg test with 2-400mg Deca and 2 tabs of Anadrol.
Keep in mind this was the 90s so test was 200mg/cc max and Deca was 100mg/cc. I never injected a lot, I just didn't want to.
I would add things pre-contest like Winny-V or Parabolan or Primo.
I went up to I think 1250 test using Sustanon amps for a short time and didn't feel a benefit. I pushed up close to that once or twice again, but never for more than a month. This was me listening to the "current wisdom" and not my own body or experience.
Today it is 300mg test, 100mg tren, 100mg mast (2.5cc/wk). I will toss in an oral, usually Anadrol every other cycle.
My next run will probably be 150mg Test and 3-600mg Deca. This is all off-season now, as I have no intention to compete again.
