Creator description · original language
As someone with a PhD in molecular and cellular oncology who spent 25 years studying cancer cells, I think about aging differently than most people — and it's not about stopping it. It's about how well you get there.
In this video, I break down:
→ The difference between chronological age and biological age
→ The hallmarks of aging — and why no single supplement or peptide "reverses" it
→ Epigenetics, explained through identical twins → My own DunedinPACE result (the "speedometer" for how fast you're aging)
→ My full personal protocol: how I use testing to decide what to invest in, including the specific peptides I currently have in rotation
This is educational content based on my own self-experimentation — not medical advice. I'm a scientist, educator, and coach, not a medical provider. Peptides mentioned are research-use-only and used under licensed provider supervision. Talk to your own doctor before making changes to your own protocol.
