Episode Overview

This episode delves into the rapidly growing, unregulated market of “black market” peptides—compounds touted for health, beauty, and fitness benefits, but largely existing outside legal oversight and scientific validation. Through investigative reporting and real-world anecdotes, the hosts and guests break down what peptides are, why interest has exploded (especially on social media), and the risks and regulatory questions swirling around them. The episode spotlights the tension between people’s desire for self-optimization and the lack of hard evidence or medical oversight backing most peptide products.

Key Discussion Points & Insights

1. What Are Peptides? (02:15–03:12)

• Definition: Madison Mueller explains that “peptides are essentially… Insulin’s a peptide, GLP-1s are a peptide. There are a lot of legal drugs out there that are peptides, common drugs. But…we're talking about black market peptides, the ones that are not approved drugs that don’t really have the rigorous safety [checks].” (02:29)
• Context: Insulin and GLP-1s are legitimate, prescribed drugs, but the episode focuses on unregulated peptides often found in home fridges “in little vials of powder…imported from overseas, usually Chinese manufacturers,” says Amanda Mull (03:12).
• Preparation & Storage: "They're reconstituted with a special type of sterile liquid so that they can then be drawn up into a syringe and injected...once reconstituted, they have to be kept cold." (Amanda Mull, 03:17)

2. Why Are People Using Them? (03:49–04:37)

• Motivation: Amanda Mull: “People are looking for a magic pill. As always, from the beginning of humanity, people have been looking for substances that can solve various problems.” (04:06)
• Claims: Uses include weight loss, tanning, sleep improvement, and more. “Once GLP-1 drugs got popular…people started looking for other peptides to do other things in their bodies.” (Amanda Mull, 04:06)

3. Do Black Market Peptides Work? (04:37–06:02)

• Evidence Gap: Madison Mueller: “They do work. They’re life changing. But the evidence and the safety data and the effectiveness data is not there to back it up. So it’s hard to know and it’s hard to tease out.” (05:06)
  • Users often stack regulated and unregulated peptides, making effects hard to attribute.
  • Positive lifestyle changes that coincide with peptide use (e.g., working out, eating better) further muddy the waters.
• Notable Quote: “It’s just a bit hard to know what’s actually happening.” (Madison Mueller, 05:33)

4. Regulation and Legal Gray Areas (06:00–08:32)

• Legal Status: “These drugs are illegal to sell, illegal to prescribe. They are black market substances. They are not approved for legal sale in the United States.” (Amanda Mull, 06:17)
  • Even versions of approved drugs, when obtained outside formal channels (e.g., as vials of powder), are illegal.
• Cultural & Political Contradictions: Amanda Mull breaks down the “Make America Healthy Again” (MAHA) crowd’s paradox—“It’s not an incoherent position towards science…but…it enables a person to feel like they are taking control of their health and not listening to what the government or big Pharma says.” (07:13)
• RFK Jr. and Regulatory Change: Noted advocate for peptides who asked the FDA’s regulatory committee on compounded drugs to explore compounding some peptides domestically (07:48).

5. Black Market Supply Chains & Key Players (08:32–10:37)

• Spotlight: Peter Magic
  • “He owns a testing lab outside of Prague that has sort of become like a central node in the trade of black market peptides across the world...he realized there was an opportunity to purity and sterility test these substances.” (Amanda Mull, 08:57–09:27)
  • On Safety: Mueller: “He can test these substances, he can say that they are what they purport to be. But…some people aren't changing the syringe or they're not cleaning properly. And there can still be things in these drugs that are not necessarily safe.” (09:40)
  • Risks include medication interactions, poisoning from prolonged use, and lack of medical oversight.

6. The Medical Community’s Viewpoint (10:37–11:12)

• “Some doctors are also fans…but they think that some of the benefits might outweigh the risks. It’s definitely challenging.” (Madison Mueller, 10:40)

7. Will Peptides Become Regulated Soon? (11:12–12:31)

• Hurdles to Legalization: Amanda Mull:
  • “The FDA’s process for approving drugs like this…requires…very expensive, lengthy clinical trials…because these drugs exist outside of…normal patent process, no single company is really incentivized to go through the effort of getting these drugs tested and approved…” (11:12)
  • Current FDA, influenced by RFK Jr., is exploring alternative paths but faces daunting legal and market barriers.

8. Advice and Cautions for Consumers (12:31–13:20)

• Safety First:
  • Madison Mueller: “It will be really important for people to tune into this FDA meeting that's happening in July where they will literally be reviewing the evidence and the data around these things. There are independent experts on this committee that will be talking about that.” (12:46)
  • She further cautions that “most of the people that we talk to say there really isn’t any evidence or human data on this.”
• Individual Choice: Amanda Mull: “Many of their proponents agree that there's not any data, but they think that they should be able to give it a shot if they want to.” (13:12)

Notable Quotes & Memorable Moments

• On the rise of peptides: “People are looking for a magic pill. As always, from the beginning of humanity, people have been looking for substances that can solve various problems.” (Amanda Mull, 04:06)
• Regulatory contradiction: “It’s not an incoherent position towards science…but a coherent position in regards to an attitude toward authority.” (Amanda Mull, 07:13)
• On black market risks: “He can test these substances, he can say that they are what they purport to be. But…there’s just no oversight. So any number of things can happen.” (Madison Mueller, 09:40)
• On future prospects: “No single company is really incentivized to go through the effort…because once they’re approved, then all their competitors can make them and sell them as well.” (Amanda Mull, 11:56)

Conclusion

This episode exposes listeners to the double-edged sword of the peptides boom: the allure of rapid self-improvement via “magic” injectable compounds balanced against real safety concerns, scientific uncertainty, and regulatory blind spots. As public interest and high-profile endorsements surge, the stakes may soon shift, with the FDA’s July meeting looming as a major turning point for the legitimacy and oversight of these compounds.

“There really isn’t any evidence or human data on this... hopefully that will make people aware of the situation.” (Madison Mueller, 13:02)

[Venture Global Representative]

You're listening to Bloomberg Business Week with Carol Massar and Tim Stanovec on Bloomberg Radio.

[Host/Interviewer]

This is about the Million dollar peptides Gold Rush. And as I was reading it I thought about a friend of mine who recently shared that he is the father of teenage boy or two. He found some peptides in the refrigerator in the basement.

[Amanda Mull]

Well, safe storage at least safe storage,

[Host/Interviewer]

but not necessarily safe. Injection.

[Amanda Mull]

Yes.

[Host/Interviewer]

Or so safe part of the world or place that these came from. And that's really at the heart of the story. First of all, if people aren't familiar with peptides, Madison, start us out. What are they?

[Madison Mueller]

Ooh, that's a good question. One of the things is that most people actually don't know what they are, don't know how to explain them even if they think that they do. And a lot of people are injecting these things, don't really know what they are. But peptides are essentially, I mean if you think about it, Insulin's a peptide, GLP1s are a peptide. There are a lot of legal drugs out there that are peptides, common drugs. But when we're talking about peptides, so putting it in this sort of context, we're talking about black market peptides, the ones that are not approved drugs that don't really have the rigorous safety.

[Host/Interviewer]

These were the ones in the fridge of the teenage boy?

[Madison Mueller]

Yes.

[Co-host/Interviewer]

Okay, this doesn't sound good. What exactly are black market peptides, Amanda?

[Amanda Mull]

Well, they are. Well, they start off as like, little vial, little glass vials of powder that are imported from overseas, usually from Chinese manufacturers, which, it should be noted, also produce a lot of the active pharmaceutical ingredients and perfectly legal, perfectly safe drugs. They're imported from overseas, little glass vials of powder. They're reconstituted with a special type of sterile liquid so that they can then be drawn up into a syringe and injected. And so once they're reconstituted, they have to be kept cold in order to be kept safe. So that's why they're in the fridge.

[Co-host/Interviewer]

Why do people want them?

[Amanda Mull]

A whole host of reasons for everything, basically.

[Co-host/Interviewer]

To sleep, to tan.

[Host/Interviewer]

One thing that may inform the question is Carol's not on Instagram. Maybe she doesn't see the same things I do.

[Co-host/Interviewer]

Well, tell us about, like, what is going on?

[Amanda Mull]

Well, people are looking for a magic pill. As always, from the beginning of humanity, people have been looking for substances that can solve various problems. And people are hopeful because GLP1 drugs are so effective at helping people lose weight and work. They work, they work. They're safe, they're effective. They've been used in large patient populations. So once those got popular, people started looking for other peptides to do other things in their bodies.

[Host/Interviewer]

Well, Madison, you cover the regulated, mostly the regulated pharmaceutical industry as a healthcare reporter. Do the black market peptides work? Does the stuff that is sold as part of, I don't know, a filler treatment at a med spa in Brooklyn or the stuff that a celebrity talks about as a secret service seems to

[Co-host/Interviewer]

know a lot about this.

[Host/Interviewer]

It's all in the.

[Co-host/Interviewer]

I know, I know.

[Chase Bank Advertiser]

Just kidding, just kidding.

[Host/Interviewer]

Do they. Do they work? Like, is there the evidence to back it up?

[Madison Mueller]

That is the key question. Because the thing is, like, if you ask someone, and we asked many people in the course of reporting this story, several of whom are in the story, they do work. They're life changing. But the evidence and the safety data and the effectiveness data is not there to back it up. So it's hard to know and it's hard to tease out. I mean, one of the people that we talk to in the story is on tirzepatide, which is the active ingredient in Lilly's drugs.

[Amanda Mull]

The.

[Madison Mueller]

They're also on multiple other things. And so it's hard to know whether the effects that they're experiencing, the anti inflammatory effects, the weight loss, all of the things are because of Lilly's drug, which we know does work, or the other things that they're on. And you know, sometimes when people start taking these peptides, they might also start working out more or start eating healthier, doing other things. And it's just a bit hard to know what's actually happening.

[Co-host/Interviewer]

So the FDA is all over this, right?

[Madison Mueller]

Well, all over it is a little degenerate. There was a little sarcasm there, yeah.

[Amanda Mull]

I mean they're all over it in certain ways.

[Co-host/Interviewer]

Well, tell us where are they on this? Because it's obviously people are interested, people are consuming them. Right. And so where are they?

[Amanda Mull]

Yeah, well, I think perhaps we haven't said this yet, but these drugs are like illegal to sell, illegal to prescribe. They are black market substances. They are not approved for legal sale in the United States. And the ones that are approved for legal sale, if you're getting them in vials of powder, you're getting an illegal version of them that's being sold outside of patent.

[Chase Bank Advertiser]

So it won't be the first time

[Co-host/Interviewer]

that somebody consumes an illegal substance. Right?

[The Hartford Advertiser]

Yeah.

[Amanda Mull]

Illegal drugs are something, have a long and storied history in this country.

[Co-host/Interviewer]

Okay, but what's worrisome though, right, and where is the government on this?

[Amanda Mull]

Right, so RFK Jr. Has said he's a peptide fan first and foremost and has said that because there is this overwhelming. Yeah, hold on.

[Host/Interviewer]

But that's such a. Hold on, hold on. I just wanna stop you there because that's contradictory in some way because a lot of his supporters, Madison, you've been on our program talking about this. A lot of the Make America Healthy Again people are sort of anti glp. One which you helpfully shared with us at the beginning is a peptide. So is there some sort of contradiction there?

[Amanda Mull]

They're being sort of caught in a bit of a corner that they've backed themselves into, I would say, because there is, you know, I. The way I would think about it is that it's not an incoherent position towards science or scientific proof or towards these drugs, but it's a coherent position in regards to an attitude toward authority. So getting these things outside of normal medical guidelines, outside of normal chains of expertise, outside of a doctor's office in most cases is really an effective pitch for the Maha crowd for a lot of different things because it enables a person to feel like they are taking control of their health and not listening to what the government or big Pharma says so. The existence of these peptide supply chains outside of regulatory control is very enticing to the whole Maha mindset, I would say so. RFK Jr has said that he is a fan of peptides and he has instructed the FDA's regulatory committee on compounded pharmaceuticals to look into allowing some of these drugs to be made by compounding pharmacies, which wouldn't approve them for regular pharmacy sale in like, your local cvs, but it would make them available through, like, sterile facilities in the us.

[Co-host/Interviewer]

Well, isn't that going to tick off Peter Magic

[Madison Mueller]

or it will be more business?

[Co-host/Interviewer]

Yeah, tell us about him because that's kind of the character that kicks off your story.

[Madison Mueller]

Do you want to go into it?

[Chase Bank Advertiser]

Sure.

[Host/Interviewer]

So he drives a fast car?

[Madison Mueller]

Yes, that's all you need to know.

[Amanda Mull]

Peter Magic is a chemist with a lab outside of school.

[Co-host/Interviewer]

Is Magic his real name?

[Amanda Mull]

Yes, as far as we can tell. As far as we can tell.

[Co-host/Interviewer]

Keep going.

[Amanda Mull]

He owns a testing lab outside of Prague that has sort of become like a central node in the trade of black market peptides across the world. Because he started his business to test black market anabolic steroids and peptides first gained sort of a foothold through some of the same users, like fitness hobbyists, biohackers, people who are interested in perfecting their own form. So he realized there was an opportunity to purity and sterility test these substances because, like users of anabolic steroids, people want them and they want them outside of legal means, but they still don't want to like, die because they injected something.

[Host/Interviewer]

So, Madison, does that mean they're safe still?

[Madison Mueller]

Not necessarily. I mean, the thing that, you know, he can, he can test these substances, he can say that they are what they purport to be. But, But a lot of these people like the practices of injecting yourself with the medication. Like, some people aren't changing the syringe or they're not cleaning properly. And there can still be things in these drugs that are not necessarily safe. And the practice of how people are actually taking and consuming these medicines, there's just no oversight. So any number of things can happen. And that's sort of the problem. I mean, there can be medication interactions, you can be. One of the things is with some of these peptides, you need to take blood tests, you need to cycle on and off of them so you're not essentially like poisoning yourself. And not everyone knows that. So it's like all of these things that in, you know, with normal drugs and in a normal setting would have some type of doctor involved or some type of oversight are just not happening.

[Co-host/Interviewer]

What does the medical community say? What do doctors say?

[Madison Mueller]

Well, we. There are some doctors who are also fans of them. And like, we talked to some of them in this story. And those doctors are more comfortable, I would say, with the risks or aware of the risks, but they think that some of the benefits might outweigh the risks. And so it's. It's definitely challenging.

[Host/Interviewer]

Amanda, do we get to a point where in a couple of years this is just going to look so quaint because these have made their way through a formal approval process and we'll be able to buy legitimate peptides at CVS?

[Amanda Mull]

Probably not. The FDA's process for approving drugs like this for regular commercial sale is pretty specific in the kinds of proof that it requires. And in order to. This is the same reason why it's been until, you know, last week. It was years and years since we had gotten a new sunscreen filter approved, even though there's lots of effective ones being used in Europe and Asia for decades. The FDA requires, like, somebody to invest in a lot of very expensive, lengthy clinical trials in order to create the sort of safety and efficacy data that it requires in order for these drugs to be sold commercially. So because these drugs exist outside of, like, the normal patent process, that would normally allow a single company to profit off of them exclusively for a period of time after their approval. No single company is really incentivized to go through the effort of getting these drugs tested and approved in the way that they normally would be, because once they're approved, then all of their competitors can make them and sell them as well. So the fda, at least under rfk, seems intent on, you know, sort of making an end run around that type of legalization, or at least that's the issue that they're going to take up in a few weeks.

[Co-host/Interviewer]

We only have about 50 seconds left here. I'm just like, in reporting this out because there are people, as you say, it's all over social. And people are looking at this and thinking, should I take this? What's a quick, like, thought to them, Madison? Or what's your. What. What did you learn in kind of doing this?

[Madison Mueller]

I mean, I think that it will be really important for people to tune into this FDA meeting that's happening in July where they will literally be reviewing the evidence and the data around these things. There are independent experts on this committee that will be talking about that.

[Co-host/Interviewer]

Yeah.

[Madison Mueller]

And most of the people that we talk to say there really isn't any evidence or human data on this. So I think like hopefully that will make people aware of the situation.

[Co-host/Interviewer]

More 15 seconds for you Amanda.

[Amanda Mull]

Well, I think many of their proponents agree that there's not any data, but they think that they should be able to give it a shot if they want to.

[Co-host/Interviewer]
