If you’re taking mucuna capsules it would be better to take them half an hour before a protein shake. If you’re using the powder, in theory it would be better to have before as well, but to be honest, for the convenience and to disguise the taste I think you’d have more compliance by taking it in the shake. Realistically, having protein every 3 hours there’s unlikely to be a time when you system isn’t processing amino acids, except perhaps first thing in the morning. This is actually the best time to take mucuna so I’d take it then.
The benefits that patients receive from their individual TRT program can be affected by the presence of other health issues, such as obesity or by other prescribed medications that they may be taking. But since the benefits of testosterone cypionate and other medically prescribed forms of TRT accrue month by month as you use your treatments, as long as you are following your hormone therapy doctor’s instructions faithfully. Furthermore, the benefits will continue for as long as you are continuing to use your doctor prescribed treatment program.
The second theory is similar and is known as "evolutionary neuroandrogenic (ENA) theory of male aggression".   Testosterone and other androgens have evolved to masculinize a brain in order to be competitive even to the point of risking harm to the person and others. By doing so, individuals with masculinized brains as a result of pre-natal and adult life testosterone and androgens enhance their resource acquiring abilities in order to survive, attract and copulate with mates as much as possible.  The masculinization of the brain is not just mediated by testosterone levels at the adult stage, but also testosterone exposure in the womb as a fetus. Higher pre-natal testosterone indicated by a low digit ratio as well as adult testosterone levels increased risk of fouls or aggression among male players in a soccer game.  Studies have also found higher pre-natal testosterone or lower digit ratio to be correlated with higher aggression in males.
