Sliced Bread - Series 17: Experimental Peptides

Is it OK to take experimental peptides like the Wolverine Stack?

These are what bodybuilders, longevity gurus, and online influencers are all talking about: experimental peptides. They're chemicals that you can buy online, in packages with names like the Wolverine Stack or the Glow Stack. The websites say "for research purposes only" but talk about their supposed benefits for wound healing and de-aging, and lots of people have been injecting them in a bid to heal faster and look younger.

Sliced Bread listener Steve is excited - and has even tried them for himself - but listener Sophie is worried. Both of them are asking whether there's any evidence behind the fantastic claims.

To find out the truth, Greg Foot is joined by Dr Andrew Steele, longevity scientist and Director of the Longevity Initiative.
