A huge number of businesses have spent the last few years adopting AI, and my company, steven.com, is no different. But here's the thing, most companies actually have no idea whether or not it's working for them. Their teams might be using AI, they might be spending money on AI, and their leaders might be telling the board that they are an AI-enabled business, but they'd also likely struggle to explain where in the business AI is helping. The issue is there's no easy way to see whether it's delivering value or working effectively unless you're using our sponsor, Liridin, which runs seamlessly as a browser plugin or desktop agent and shows you exactly how AI is being used across your organization, what it's actually producing and where the real opportunities in your business are. That way, you're able to make data-backed decisions instead of just guessing all the time. I love anything that kills the guesswork. So if you want to be a company that's informed with your use of AI and accelerate your company's AI transformation, head to liridin.com and book a demo now. That's larridin.com and book a demo now.

This may be the most controversial thing we have on this table. This is a peptide that absolutely torches belly fat at a disproportionate rate. And what we found is not only do patients lose an incredible amount of weight, but they also get the best improvements we've ever seen in their liver health. It's absolutely wild. And I think this is going to be a trillion dollar drug when it comes out.

Steven Bartlett (1:23)

And I brought you here because you're an expert on the subject, and it's worth saying that there was some significant news about this.

Alex Tatem (1:28)

Correct. From the FDA saying that in July, they are going to consider legalizing seven peptides. And by pharma's estimate, it might be the most dangerous thing to their entire business model.

Steven Bartlett (1:38)

So do you think it is plausible that big pharma didn't want these in the hands of regular people because they can't patent this and it's powerful?

Alex Tatem (1:45)

110 percent. Because the question isn't what can peptides do, it's what can't they do?

Steven Bartlett (1:50)

And we've got several peptides here in front of us. I want to go through all of them.

Alex Tatem (1:54)

Let's do it. So this is probably the most well-known peptide for skin complexion, and it improves quality of hair and nails. And then epithalon is maybe, maybe not going to be the fountain of youth. But I'm very skeptical as far as that goes. Next, we've got this. If you injected that at night, it would improve your quality of your sleep. Next, melanotan too. And this will actually end up giving you a deep tan in response to just a little bit of UV sun exposure. It will also give you some of the most impressive erections you've ever had in your life, so be warned.

Steven Bartlett (2:23)

And what else have we got?

Alex Tatem (2:24)

Oh my gosh. There's methylene blue, where people take it and they think it's going to make them live forever. Don't take this. It literally will stain your nails blue and your hair blue. These two here stimulates building muscle. This one can aid with healing after an injury. And then there's this, this, this, this.

Steven Bartlett (2:37)

It's crazy.

Alex Tatem (2:38)

It's wild.

Steven Bartlett (2:39)

So why don't I take it?

Alex Tatem (2:40)

Well, we need to talk about that because there are trade-offs.

Steven Bartlett (2:42)

But also outside of the world of peptides for a second, I've got these three vials. Do you know what those are?

Alex Tatem (2:47)

Yeah. This is unfortunately our future if we're not careful.

Steven Bartlett (2:50)

Explain.

Alex Tatem (2:51)

So what we've got here is representing the fertility trajectory for young men. I'm so scared.

Steven Bartlett (2:59)
