I have been reading, maybe too much, about IGF and HGH as I am considering if I should one or other or even both. Must admit that all this reading has made me more confused than less and seeing the quality of the responses on this forum I am going to put my situation down here and see if you can assist me.

I am a 40 year old man that used to be quite serious about bodybuilding but now I have moved more into a training program used by professional MMA competitors. This training combines a lot of cardio with weight training.

Anyway, my goal is to to gain more lean mass (I am currently at around 8% bodyfat) and to improve my overall fitness and well-being. Being 40 makes it considerably harder than before so I am looking for something that can help me reach the next level.

I have been offered both HGH and IGF, and after reading about those I am seeing some suggest you take HGH, some that suggest to take only IGF and some to take both.

I would be extremely grateful if someone that knows about this subject could give me advice based hopefully on experience.
