I'm currently using Zmass-PM, and I was wondering if it needed to be cycled. I just got done w/ my first 30 days and I've seen a huge improvement, and I just bought my second bottle today, and was wondering if I could start right away. Also I was wondering if anyone has used or heard about Twinlab's Andro Nitrate Fuel, it seems to be a really good test booster, and I might stack it w/ Zmass for some better results.
