Thinking about the fictitious HALO universe (Spartan soldiers, Master Chief):

Do we humans need some sort of ‘augmentation’?

In practical terms, the best way to become ‘enhanced’ (naturally) is maximal movement, walking, time outdoors, and sun exposure for the day. Intermittent fasting during the day, only breaking fast for a huuuuuuge massive dinner meal (meat heavy).

For stimulants during the day (prior to noon), black on black on black coffee. When tired, take naps.

To become more hyped up, media which hypes you up. Can be music, show series, films, cinema, etc.
