Gray peptide vendors embrace stablecoins as safety fears deepen

A recent report from Chainalysis shows that cryptocurrency is increasingly being used to facilitate transactions in the illegal peptide market, which is rapidly expanding.

Summary

  • Chainalysis said gray-market peptide sales topped a $100 million annual run rate as buyers increasingly used crypto payments online.
  • The report said first-quarter peptide sales reached $32 million, rising 159% from $12 million in the previous quarter.
  • Chainalysis found that larger peptide vendors relied more on stablecoins to reduce exposure to Bitcoin’s sharp price swings.

Chainalysis reports that sales of peptides, often purchased for uses not officially approved, are now exceeding $100 million per year. This growth is driven by increasing interest in online wellness and a desire for more affordable products, leading people to buy from suppliers outside the country. The company, which analyzes blockchain data, noted that sales reached $32 million in the first quarter of 2026 – a significant jump of 159% from $12 million in the previous quarter.

The increase in sales is connected to growing public interest in peptides – the building blocks of proteins used in health, fitness, and wellness products. According to Chainalysis, the popularity of drugs like Ozempic and Wegovy has brought related products into wider online conversations, though many people are purchasing unregulated versions.

Crypto becomes payment backbone

Chainalysis reports that banks and credit card companies frequently block payments for prescription medications and unregulated products. Because of this, many sellers are now using cryptocurrency to process payments through alternative channels.

Chainalysis calls the trade in peptides a “gray market,” meaning products are sold directly to consumers by overseas suppliers, often without branding. The company notes that many of these supplies now come from Chinese chemical manufacturers, in part because some sellers have difficulty using traditional banks.

Chainalysis’s latest report indicates that major companies are becoming more systematic in how they accept cryptocurrency payments. The research shows suppliers frequently use both Bitcoin and stablecoins, but larger businesses tend to favor stablecoins more often.

Stablecoins dominate larger orders

Chainalysis found that for vendors receiving deposits of $1,000 or more, stablecoins were the most common form of payment. This suggests sellers might be using stablecoins to avoid the price volatility of Bitcoin, especially when dealing with large orders.

The report also looked at how the peptide market is similar to other online research-chemical networks that use cryptocurrency. According to Chainalysis, some companies previously involved in selling chemicals used to make fentanyl now also sell peptides, or have simply expanded their businesses to include them.

Chainalysis highlighted Shanghai Sigma Audley as one example, noting the company—which they suspect is connected to international drug trafficking—received over $1 million in bitcoin and $3.59 million in stablecoins from selling chemicals used to make fentanyl. The company later began selling peptides as well.

Testing spend falls per buyer

Chainalysis also pointed out potential safety issues with the products. They noted that several wallets used to purchase peptides from China had previously sent money to Janoshik, a Czech firm specializing in independent chemical purity testing.

Chainalysis found that while more people are trying out products, the amount they’re spending on those initial tests has decreased significantly. The average test purchase is now around $8 per buyer, an 88% drop, even though Janoshik is seeing an increase in the total number of products being tested due to the larger customer base.

The report highlights that many people entering the peptide market are new to both cryptocurrency and unregulated medications. Chainalysis notes this increases risks for buyers, who may not be aware of issues like product authenticity, how payments are tracked, or the legal restrictions surrounding these products.
