Unregulated peptide exports from China create reputational and regulatory risks that threaten the country's ambition to become a global pharmaceutical leader.

China showed seven years ago that when its leaders decide to crack down on an illicit trade, they can move fast. A ban on all forms of fentanyl, imposed under U.S. pressure, demonstrated how quickly authorities can mobilize. The same urgency now needs to apply to unregulated peptide exports.
Peptides are short chains of amino acids that act as chemical messengers in the body. Some, like insulin and the active ingredient in Ozempic, are legal and widely prescribed. A vast array of injectables has grown popular among biohackers seeking bigger muscles, sharper cognition, or better looks. Two main problems plague products like BPC-157, TB-500, and melanotan. The molecules have not been adequately tested for safety or efficacy in humans. The U.S. Food and Drug Administration banned some of them three years ago over those concerns. Misuse can upset the body's hormonal and metabolic balance, raising the risk of serious side effects including organ damage. A grey-market boom means dodgy products are often sold by online merchants.
China, with its vast chemical and pharmaceutical industries, appears to be the main source. The country has about 1,000 online sellers targeting buyers abroad, according to the Financial Times. No one should equate unlicensed peptides with fentanyl, the synthetic opioid behind nearly 40,000 overdose deaths in the U.S. last year. The parallels are real. Both can be churned out cheaply at scale and shipped across borders in small parcels, making them hard for regulators to track. Like fentanyl, peptides are marketed widely over the internet to overseas buyers even though they are off-limits at home.
The clandestine nature of the business has driven a boom in digital-asset use. Banks and credit card processors generally eschew transactions involving unlicensed substances, so buyers use cryptocurrency. Crypto payments to peptide vendors jumped 700% to $32 million in the first quarter of this year, analytics firm Chainalysis wrote in June. Some of the biggest vendors are Chinese chemical makers that were, until recently, mainly supplying the building blocks of fentanyl and amphetamines to drug cartels, according to blockchain records.
This on-chain peptide economy is expected to exceed $100 million annually, propelled by endorsements from celebrities like podcaster Joe Rogan and actor Jennifer Aniston. Industry insiders estimate the unregulated market is worth between $1 billion and $3 billion.
The trade is one-sided. Unauthorized peptides attract little interest inside China. 'Looksmaxxing,' an online subculture focused on physical attractiveness that can go to extremes, has failed to gain traction. China's disenchanted Gen Z has instead responded to a slowing economy and high jobless rates with silent rebellion in the form of ugly work outfits or vows to 'lie flat.' Self-improvement is not on the agenda.
China also has reputable peptide makers. Companies such as WuXi AppTec have benefited from soaring demand for ingredients used in blockbuster GLP-1 diabetes and weight-loss drugs, including the active ingredient in Eli Lilly's obesity treatment Zepbound.
Beijing may seem to have little incentive to crack down on a shadow business that barely affects its own citizens. That is shortsighted. As with fentanyl, the grey peptide market creates reputational, regulatory, and geopolitical risks. Singapore has declared it illegal to sell unregulated products. Australia has warned of serious side effects such as liver damage and severe allergic reactions requiring hospitalization. The U.S. is bucking the trend; external advisors to the FDA have recommended relaxing restrictions on some peptides.
More than most countries, China understands the national trauma that can accompany the unchecked spread of potentially dangerous substances. That history has shaped decades of tough anti-drug policies at home. Allowing it to become the world's main source of unregulated peptides would sit uneasily with that legacy.
China has something else to protect: an ambition to become a global pharmaceutical leader. World-class manufacturers should not have their reputations tarnished by a grey market flourishing alongside them. Bringing unauthorized exports under tighter control would only reinforce that goal.
