I'm on my first cycle of sust 250, which has followed two 1AD cycles. You might want to invest in some clomid for post cycle therapy, depending on how this 6 oxo is working. I know I crashed really, really hard after a 6 week cycle of 1AD and retained only about 60% of my gains. I also front loaded and did a pyramid coming down...if you use the search function and come up with my old post. I came down slowly over the last two weeks to prevent a crash and it worked like shit. My best gains probably came from my first 1AD cycle at 300mg a day.
I'm sure you have your reasons for giving up the gear, so I'm not going to try and convince you otherwise. 1AD is the best supp that I've ever taken, but I believe I had more sides with it than my current cycle (specifically acne and mood swings). On the plus side, I feel that my pumps were alot better...but that's about the only thing. I highly recommend 1AD to friends and clients alike, but will probably never take it again.
