Coach Kai, for some1 approaching 50, your physique as a natural is a RARITY esp. in Asia. Health reasons aside and purely in terms of physique and aesthetics, hopping on TRT will merely make you one of many. Not saying that you should not hop on it but perhaps, given that natural bodybuilding is on an upward trend, it may not be a wise choice for your brand/business moving forward and something for you to consider should the time come. Personally, I also feel that it would have people overlook the hard work and CONSISTENCY you have put in over these 20 years. I have certainly been inspired by them and hope that more people can be too.
