I'm 20 years old and was wondering if a 4 week cycle of 1-ad and 4-ad would be good for me. I have read a good bit about the 2 but was wondering what would be the best brand and what to take post cycle. I have taken cell tech for a while off and on. I gain good with it. I just want to try something new and better, but would like to get back on cell-tech right after the 1-ad and 4-ad. thanks for the help
