I am 51and started powerlifting about 6 years ago. I have always kept my back flat on the bench with a closer grip and with a really high rack height like 18 on a ER rack just like what I did in college (really long arms) shoulder extended up not kept down. I have over the last 4 years tried a powerlifting style multiple times by arching my back bringing the rack height down to 14 and spreading my grip. I have given it months of training but my max is always stronger with my old bodybuilding style of bench… I can’t explain it because my range of motion is about 5 to 6 inches more on downward stroke and the same on upward stroke when using the bodybuilder style. It makes no sense! But your article is the first one that I read that states a bodybuilding bench recruits more muscles. Could that be the reason why I am stronger with the BB style? Its frustrating because everything you read states the opposite. Any theories?
I think this approach is fine. I must say having been doing this for years, treating hundreds and thousands of men I have been underwhelmed with the results with topicals. Injections can cause peaks and valley and I have many younger men inject twice a week that smooths out the peaks and valleys. I think it is appropriate to follow the advice of your primary doctor and endocrinologist. I have just seen too many men spend months or years with gels with sub optimal results. Many men are diagnosed with depression and are not really depressed (I have no idea if this applies to you), but the presumed depression is base dupon low T.
My recommendation would be to pursue this but if a few months pass and results are modest consider another approach. Pellets are one approach to have smooth levels of T and are placed every 4 months.
Natural bodybuilding is a bodybuilding movement with various competitions that take place for bodybuilders who abstain from performance-enhancing drugs . This categorically excludes the use of substances like anabolic steroids , insulin , diuretics and human growth hormone .  If a bodybuilder meets the requirements of the sanctioning body (the recognized group or authority that sanctions and validates competitions) that they are competing in, then they are considered to be "natural". There are numerous sanctioning bodies who provide their own rules and regulations that govern the competition procedures, event qualifications, banned substance lists, and drug testing methods. Doping detection methods include urinalysis and polygraph testing, and federations typically conduct these tests on the day of competition, or shortly before. Out-of-season testing, although less common, may also be used. Each organization will specify within its rules the length of time that its athletes should be drug-free, which may vary from testing clean on the day of the event, to being drug-free for a number of years, right up to a lifetime natural requirement.
