At this is point, you're pretty much doing your first cycle all over again. So you can make great progress on a very moderate program. Moderation is the key to controlling side effects. At the bottom of this response, I will outline a good mass building plan. If you keep your diet in check, you can make good progress and not get overly fat in the process! As for gyno, a lot of guys have minor gyno. You just need to use enough AI to control estrogen. So keep an eye on yourself and if you need to, add more adex. Your gains and maintaining your muscle gains after are all going to come down to nutrition. The gear will allow you to make faster progress, as long as your diet is good. And then after you have gained the muscle on cycle, it's simply about eating enogh to support your new muscle. Of course, you need to find a balance. Too much food, especially carbs and fats, and you will gain body fat. Too little food and your body will shed muscle. Muscle takes a lot of nutrition to support. The easiest thing your body can do to be more effecient, is to shed muscle and then require less fuel.
As for lab work, I see a dr that is aware of what I do. She does not supply me with steroids, but she will keep an eye on me and make sure that I am as healthy as possible. So you either have to talk to your dr openly. Some drs will keep it off the record. Or you need to find a Dr that will be accept that you are a gear user. Or you can have labs done online. A lot of guys do. Here is a site that a lot of people use.
