Yeah that is really impressive , pretty much for any age.
But this guy is using steroids and GH and I think the main reason why it's a lot harder for older guys to be in great shape is the decline of testosterone and growth hormone levels - so you can't really compare him to your average natural 65 year old guy of course. I also think that this guy built all that muscle when he was still a lot younger and is now just trying to hold on to it... I doubt he has really made any significant progress in terms of muscle mass over the past few years.
Vince is claiming that age does not matter when it comes to building a good body even without steroids... which is obviously complete bullshit and his pictures are a sad proof of this. Claiming he is bigger now than when he won the Mr. Canada just shows how delusional he really is.
Your post peaked my interest largely because I am 67 years old, still bodybuild and I am on TRT (testosterone replacement therapy). Without a doubt, one's testosterone levels are a benefit to their good health at any age. Low testosterone can be caused by a number of things including old age. I was diagnosed with low testosterone many years ago. However, my doctor at the time would not agree to testosterone replacement therapy because I also had an enlarged prostate. Fortunately for me, he retired forcing me to seek a new urologist. My current doctor, a urologist, diagnosed me with hypo-gonadism which was causing me to suffer from low testosterone about three years ago. I have been on TRT ever since. I can tell you that it has made a significant difference in my life and my good health, mental and physical. One of the many benefits is that weight training is more successful in terms of results despite the fact that I am on a relatively low dose of testosterone cypionate. There are a number of other health benefits which I won't go into here.
I think it is important to distinguish between self dosed and administered steroids including testosterone and HGH and medical treatment for a variety of conditions with testosterone and/or steroids. It seems to me that some people only think in terms of black and white when it comes to steroid use. Steroids can have significant benefits to people for a variety of medical conditions. Steroids get an undeserved bad wrap because of steroid abuse....particularly in the area of sports, including bodybuilding.
