I did it and def would not do it again. Mine as well run the SD for 6 weeks straight its pretty much doing the same damage. Gains slowed in the 2nd 3 weeks. My joints got so bad I had trouble lifting the 3rd week of the 2nd cycle. I just felt like **** basically the whole 2nd cycle. PCT was also more difficult do to the suppression I encountered from the running the 3on2off3on. 1st 3 week cycle bench went up 50lbs. 2nd 3 weeks went up 20lbs and I felt like death the whole time. Definately not worth it overall as the 2nd 3 weeker gains weren't as good, felt bad, had to run a much longer pct to get back to normal,& now have to wait longer before I can use anything again.
