Testosterone does not increase aggressiveness; it increases competitiveness and willingness to lean into effort (challenge hypothesis).
00:36:42Andrew Huberman · Huberman Lab · May 2022

Testosterone binds the amygdala and lowers the threshold for stress and anxiety, making effort feel good.
00:05:11Andrew Huberman · Huberman Lab · Feb 2025
Estrogen, not just testosterone, is essential for libido in men; if estrogen drops too low, libido vanishes.

The pro-inflammatory cytokine IL-6 suppresses sex hormones and desire for sex independent of feeling sick.
00:09:22Andrew Huberman · Huberman Lab · Feb 2025

00:55:48Andrew Huberman · Huberman Lab · Apr 2024
Augmenting growth hormone, whether directly or via peptides, increases tumor and cancer growth risk because growth hormone and IGF-1 are indiscriminate about which tissues they grow.
01:04:03Andrew Huberman · Huberman Lab · Apr 2024
Huberman warns people wrongly assume peptides are safe or free of risk simply because they are not hormone therapies.
01:23:13Andrew Huberman · Huberman Lab · Apr 2024

Westlund reframes all dog breeds by the wolf predatory sequence — sniffers, pointers, herders, chasers, grabbers, killers — rather than by wolf-vs-mastiff genetics.
00:08:15Dr. Karolina Westlund · Huberman Lab · Apr 2025

00:28:43Dr. Karolina Westlund · Huberman Lab · Apr 2025
Claims humans have no role in any dominance hierarchy with dogs — behaviors we read as dominance are really learning, fear, or association.
00:35:58Dr. Karolina Westlund · Huberman Lab · Apr 2025
