I have been lifting for a couple years with a friend and we both weigh 155-160 but just recently decided to actually eat a lot and gain a lot of muscle mass. We were looking into something that wasn't hormonal or maybe a very mild pro hormone that with the right pre cautions wouldn't have any negative side effects in the long run. At first I was looking into hyperdrol x2 and mass fx, until I found out they weren't made anymore. I couldn't find out why, I read they had illegal substances hidden in them. I know mass fx destroyer and hard fx replaced them, but I haven't been able to find if they give good gains too, or not anymore since they were changed. Are there any other supplements like these that will work very good? My testosterone levels should be fine already, but they should be going up until my mid to late 20s, I'm just wanting pro hormone like gains, with out the side effects of possible hormone endocrine system problems later on. I've also read a little on x factor, DAA, and activate xtreme. Are there any others like this that could work really well but not shut down any natural production that my body already does and could possibly do more of later on? If these aren't promising then I will consider a mild pro hormone. I also do not want to lose any gains as much as possible when I am done with whatever cycle. Are halodrol liquid gels considered pro hormones? Are they even still available? I've read that they are and aren't and that some people say they do and don't need Post Cycle Therapy.. We both plan to use whatever we decide to bulk, and at the end of the cycle start to cut.
