Episode notes
Peptides Can Boost Hormone Production Not Replace It
- Peptide precursors like kisspeptin can upregulate LH/FSH and support endogenous testosterone production rather than replacing testosterone.
- Bioregulatory 2–4 AA peptides (from animal organs) can act as tissue-specific 'dimmer switches' for regulation.
Pro Teams Used BPC To Gain A Competitive Edge
- Professional teams have used BPC-157 to enhance training resilience and performance, prompting sports bodies to ban some peptides for unfair advantage.
- Dean recounts an American football team using BPC and then dominating competition.
Semax Nasal Spray Optimises Focus Without Stimulants
- Semax is a Russian-derived neuropeptide used intranasally to boost cognitive energy and focus; it's not a stimulant but optimises neuroreceptors.
- Dean notes fast perceptible effects via nasal delivery and strong historical human data.
