I had no idea you didn't start competing until your forties, wes! Wow - good outcome for having started at a later age than the norm.
I remember one of the IFBB pro diet coaches told me when Troy Alves still won a show as late as 2013 [almost 47 years old - the Orlando Pro in the 212-lb class] that Troy could have put about 10- to 15-lb more muscle, but made a conscious choice not to, for health reasons.
I figured you may have also made a similar choice, and didn't push it, just as Troy made that choice.
Frank doesn't seem to be concerned about risks, and I'm worried he won't be around much longer if he keeps doing this. 
I competed in AAU powerlifting and odd lift contests in the early to mid 1970`s......then did my local bodybuilding show taking 4th. in 1987, then vowed to compete again when I moved to Florida in 1993........did a bunch of contests down there, kept going, and never looked back.
I felt that I had a lot of time missed doing what I truly wanted to do (compete), so I entered a ton of contests all over the East Coast and as far west as Cleveland Ohio.
I`ve done my fair share of gear....still do, but I was never genetically gifted to be huge........ especially missing all those years.
Knowing what I know now,I still would be fairly conservative dosage wise.........I abused the fuck out of my body for far too long doing other stupid things to it.
Still got a ton of trophies and my liver and kidneys are in great condition.......I`m not in magazines,but I`m also not on dialiysis.
