Supplements

Creatine supposedly has cognitive benefits, also helps increase creatine phosphate in the muscle, which helps with strength training. It draws a bit of extra water into the muscle which increases muscle glucose. There is a mountain of observed benefit, much of it I suspect is overblown or low magnitude. Some people don't respond much to taking it, but its cheap and most people will see some benefit. Ashwagandha reduces restjng cortisol and subjective feelings of stress from environment. Generates a small but consistent increase in free testosterone, reduces muscle breakdown from exercise. Research literature similar to creatine, a multitude of observed benefits but most of the research centers around fertility (increases sperm motility, not a concern for my vasectomied hardware), stress reduction, improved response to fitness re performance and body comp. The effect of either by itself is not very impressive but noticeable if you're paying attention. Together they seem to really help me out physically and with body comp. And they're cheap....
