It is interesting what supplements women "should' take. Other than Testestorene, I don't see such "shoulds" for men.
You think older men should take exogenous testosterone? Even the the medical establishment is moving away from TRT and other "andro" administrations like gels and lotions. The bodybuilding world has learned the hard way the risks of hormone imbalance but almost none of these risks are fully expressed by the current prescription writers. Testosterone obviously naturally declines with age but abnormal levels other than present with a few rare conditions are usually due to lack of physical activity and proper nutrition. I would argue giving testosterone to a relatively sedentary male is a death sentence.
DHEA is equally dangerous in regards to hormone imbalance. The only exogenous hormone I would consider recommending to anyone unless they were an active bodybuilder is Pregnenolone. Pregnenolone is the mother of all hormones and your body will convert it to what it needs, whether it is in fact testosterone or DHEA, cortisol or maybe even estrogen..
If you are on TRT I would urge you to reassess, because while everyone may temporarily feel great on steroids the underlying imbalance will wreak havoc on your body, specifically your precious cardiovascular system.
These are just my opinions and not medical advice.
