Ok, first off , wow...lots of info. I have searched for several days..many hours and finding plenty of info, but..It seems as though everybody and everything is unique to each individual...let me give a readers digest version of me and my goal and current situation and knowledge. I am in my lower 40s, been working out bout 12 years, 5'10' bout 185 lbs. Lean, bout 12-13% body fat, fast metabolism.(yea still) I recently went to the Dr. for "low Libido" and for 4 weeks now I have received 200mg of CYP. He is now saying that he wants to start HGH, I thought he wrote IGF-1 on my chart but am told that it will be HGH, not sure which version yet or how much. 2 inj. a week for 4 weeks, then nothing for months. I inquired about DECA and he told me that "in my case" he wanted to use HGH. I am not really sure what the benfits will be for me or if I should insist on the DECA or stick with his plan for HGH. He knows I am into weightlifting but that is not "our" primary discussion. I do not really know much about this rhelm and would like to go at him a bit more informed. I can start HGH Mon, or insist on DECA according to his asst. Then do I still get the CYP as well? Sorry, maybe not readers digets but looking for a little insight form all the great members that I have read posts from. I am looking to just get a bit more muscle mass , my goal has always been to break 190 and hold it, maybe 195 but let's start at 190+ I will stop here and hope to hear back. I do have numbers from blood work if needed. Thanks all in advance.
