I have never jumped on the forum to ask anything, so here goes. I am a 34/M, 6'1 193lbs 10% bf currently. I have been working out since I was 16 years old. The last 2 1/2 years I have hit the gym harder then I have ever throughout my life. I also put my diet in check and have fluctuated between 6% to 10% bf throughout those 2 1/2 years. The base to my diet is 3 to 4 meals a day. Each meal consisting of a lean protein, handful of green veggies, and a good fat (avocado, nuts, oils, etc). I have taken test, and only test once in my life. I was right around my mid 20's when I did. I have hit a point where I have had great gains over the last few years shedding fat, and adding muscle, but over the last 6 months or so I have hit a wall. I have never thought about taking anything much past test, and obviously by the title of this post I am a complete novice. I also don't have access to any real gear. A friend referred me to one of those anti aging clinics he goes to. They took blood to test my levels. Everything came back pretty normal for a 34 year old male. My free testosterone was about 550ng. I explained my goals to the doc which were add another 5 to 10 pounds of lean muscle. The best he could do was prescribe me 150mg 15% testosterone gel applied once a day. My question is this, if I take this multiple times a day can I get myself into the 2000-2500ng where I would like to be? Secondly if I were to get myself to the 2500ng how much then would estrogen become an issue? I never had an estrogen issue back in the day but my fear is if I needed something to block estrogen how do I explain to the doc "hey I need a prescription of clomid or nolvadex because I decided to use your cream 4x the recommended dose" 
Also would I be shut down after the 3 months of taking it at that level? Being I don't have access to any gear what can you recommend I do to make sure any gains over the 3 month stint aren't lost, and can help my body go right back into making its regular test production. Anyway I know these are complete armature hour questions for what you guys usually see but nevertheless I can really use some advice from guys who are experienced. Thank you kindly in advance.
