I'm trying to put together some kind of program for my father who recently just turned 60. He is in fairly good shape for a guy his age but no where near being ripped or body building condition...which is kind of more the look he'd like to go for being mindful that he is doing it more for good health. He sent me his blood panels and every thing looks pretty good but his test levels are in the very bottom of the average range. I don't know if he would be able to go on hrt still being in the "average range." And I don't think he is quite open to the idea. Same thing for his free test levels which are lower average. My question is is if its still possible to gain muscle with his age and where his hormones are at? should I try putting him on supplementation to boost his natural test levels...should he just forget about putting on muscle at this point and worry about health? thanks guys...
