This week on Small Talk, Sarah is joined by Science Vs host Wendy Zukerman to unpack the internet's latest wellness obsession: peptides.

From BPC-157 and MOTS-c to anti-ageing injections and "Wolverine stacks", Wendy breaks down what peptides actually are, what the science says, and where the line sits between promising medical research and wellness-industry hype.

They discuss biohacking culture, social media testimonials, Big Pharma conspiracies, why Australia is stricter than the US, and whether we're racing ahead of the evidence in pursuit of self-optimisation.
