Anti-Doping Expert BSCG Warns That Unregulated Peptides and Research Chemicals Threaten the Dietary Supplement Industry

Los Angeles, CA ( June 3, 2026) - The rapid growth of unregulated peptides, injectable “supplements,” and research chemicals targeting consumers presents a significant reputational and regulatory risk to the legitimate dietary supplement industry, according to industry expert Oliver Catlin, President of the Banned Substances Control Group (BSCG), a leader in third-party certification and testing. These pharmaceutical “supplements” threaten the market share of the legitimate dietary supplement industry by blurring the distinction in the minds of consumers, while exposing them to risks that result from an absence of regulatory oversight.

These unapproved drugs are commonly marketed as dietary supplements even though they do not legally qualify as such. They are often accompanied by claims that they can treat injuries and the effects of aging while legitimate supplements are restricted to structure function claims. Legitimate dietary supplement brands that must follow Good Manufacturing Practices (GMP) and other compliance requirements increasingly face unfair competition from companies selling unapproved compounds without any comparable safety, quality, or compliance standards.

The increasing normalization of unapproved drugs, research chemicals, and injectable products erodes the boundary between regulated nutritional products and pharmaceutical enhancement presenting a fundamental challenge that the dietary supplement industry must address.

“The dietary supplement industry has spent decades building consumer trust around quality, transparency, and responsible formulation,” said Catlin. “When unapproved peptides, injectable compounds, and research chemicals are marketed in ways that imply they are dietary supplements, the entire category risks losing credibility while consumers are exposed to potential harm and fraudulent marketing.”

The emergence of so-called “safe injectable supplements,” peptide products marketed through research chemical loopholes, and aggressive performance-enhancement branding present a significant risk. These products operate outside established dietary supplement regulatory frameworks while leveraging the credibility of the broader wellness and sports nutrition industries.

The supplement industry has already seen the historical impacts of how illegally marketed supplements spiked with pharmaceuticals can lead to reputational damage for legitimate companies. Designer stimulants, SARMS, PDE-5 inhibitors, and NSAIDs deliberately sold illegally in products marketed as supplements, resulted in high profile concerns that damaged the perception of the industry at large and drew criticism that the supplement industry is unregulated.

Catlin sees the same danger today.

The latest trend could create long-term consequences for legitimate brands operating in sports nutrition, active nutrition, wellness, and joint health categories.

Catlin sees several areas of concern, including:

• Peptides and research chemicals marketed without adequate safety data or regulatory authorization;
• Gray market products operating outside regulatory boundaries with no GMP compliance or quality control testing requirements subjecting consumers to potential harm;
• Injectable products positioned adjacent to ingestible dietary supplements despite fundamentally different risk profiles and product characteristics.
• Products sold with exaggerated performance, recovery, anti-aging, or body-composition claims without adequate substantiation or regulatory authorization;
• Inconsistent or limited enforcement or accountability for illegal supplement products containing undeclared, unapproved, or potentially dangerous substances.

The issue is not peptides as a scientific category. Catlin’s concern is the consumer-facing commercialization of unapproved peptides, research chemicals, and injectable compounds without appropriate regulatory authorization, manufacturing controls, safety data, or quality assurance. “We support innovation, research, and legitimate science,” Catlin said. “But companies should not be using regulatory gray areas to market unapproved substances in ways that put consumers and the reputation of the supplement industry at risk. There must be a clear distinction between lawful dietary supplements and unapproved pharmaceutical drugs.”

Catlin sees the need for collective action to combat these concerns. Legal dietary supplements should not be forced to compete with pharmaceutical drugs that are making unsupported disease claims. Dietary supplements are regulated with stringent requirements for consistent quality control and identity, purity, and potency testing, while research chemicals are sold in an unregulated environment without any quality control or manufacturing standards. History has shown that it is typically illegal products sold as dietary supplements that draw negative attention to the supplement industry and erode consumer trust in the legitimate supplement industry.

As the market continues to evolve, renewed emphasis on transparency, quality control, third-party certification, accurate labeling, responsible marketing, and enforcement against products that fall outside the legal definition of dietary supplements becomes increasingly imperative.

“This is a clarion call for responsible brands, retailers, regulators, certification providers, and industry trade groups,” Catlin said. “If the industry stays silent while unregulated research chemicals and enhancement products blur the line with lawful supplements, the long-term damage to consumer confidence and category credibility could be substantial. It is time for us to work together to address this growing concern and protect the legitimate dietary supplement industry.”
