Using a basic deca/cyp cycle I have tried over and over @ 1, then 2, then 3 times/week. I have never been able to tell the difference. Sometimes it does not matter what the science says , it is what YOU says! My one regret is that I did not keep meticulous notes like drb taught me. He could tell you exactly how many times he did each protocol, the exact dates, and how he felt on the different protocols. I would like to remind everyone that keeping a diary is awesome. I should have.When you are 25 you don't realize that you may dam well still be juicing at 60.
