If you havent read up on pulse cycling, this is essentially what you are suggesting. Many people dislike it, while many others love it. I personally love it. I get awsome results with very little sides. Some people like to push the limits with pulsing 4 time a week. However, I feel that high frequency like that will inevitably lead to lots of suppression. I would feel pretty confident though that you would be able to run upwards of 40mg's of dbol 2xweek very effectively with very like suppression. I would even suggest that pulsing in this manner would likely even increase test levels. I personally pulse 2xweek and take very few breaks from pulsing at all. However, when I do take breaks, the last of which being 2 months in length, I continue to gain. This leads me to believe that I either experience very very little suppression, or if I do that I rebound back very quickely after such cycles. As I have stated before, I believe that cycles like this could possibly increase test production because of increased sensitivety of the leidig(sp?) cells to LH. This hypothesis has however not been tested, as far as I know though so dont take it as scripture. Anyways, my point is, you could very likely pulse medium to high dose dbol 2xweek with very little suppression of the HPTA. You could further reduce the chance of suppression by dosing the majority of the dbol in the morning upon rising.Thats just my 2c.
