You sound exactly like me. And just like you, I am new to all of this as well. I also recently started 100mg of Test C each week after 3 months on the gel with little improvement. I'm begining to think I have a high estrogen problem. Read the stickies, they are a god-send! Especially the one about Male Hormone Modulation. It is long, but well worth it. I copied it into a word document for more reading later.
And probably like you, I need to get more blood tests done. I've never done any anabolic steroids, and all I want is my life back. So if you want someone to talk to, I'll listen. Maybe we can do this and learn from each others experiences? Just a thought. But you aren't alone either. This is by far the best source of information I have been able to find.
You will also want to visit the AllThingsMale site. It is packed full of information. Hit me up if you need to.
