But what\u2019s in them? And are they safe?<\/p>\n
Earlier this year, three people in the United States were fined<\/a> thousands of dollars for their role in providing peptide injections, at an anti-ageing festival in Las Vegas, to two women who later became critically ill. The pharmacy board was unable to determine why they got sick, and what precisely the serums contained.<\/p>\n Our work with colleagues at Steroid QNECT<\/a>, a hotline where people can seek confidential advice about enhancement drugs, tell us people are already injecting peptides in Australia. <\/p>\n But regulation is not keeping up. And there are still major gaps in the evidence about whether peptides\u2019 anti-ageing claims stack up, and whether they are safe for humans.<\/p>\n What are injectable peptides, and why are they trending?<\/p>\n Peptides are short chains of amino acids \u2013 the building blocks of proteins. They act as chemical messengers in the body and play a key role in many processes. These include helping repair skin and calming inflammation<\/a>. <\/p>\n The body naturally produces peptides. Synthetic peptides are manufactured to mimic or enhance these natural functions.<\/p>\n Certain peptides have clear medical uses. For example, glucagon-like peptide-1 (GLP-1) drugs, such as semaglutide, are approved for diabetes and weight management \u2013 sold as Ozempic and Wegovy. This is based on strong clinical trial evidence<\/a> they are effective.<\/p>\n But a growing number of peptides are being marketed for cosmetic and anti-ageing purposes, without approval from Australia\u2019s therapeutic goods regulator. <\/p>\n Peptides such as GHK-Cu, BPC-157 and TB-500 are sold online with claims they can enhance collagen production, accelerate skin repair, reduce wrinkles, and even reverse aspects of biological ageing<\/a>. <\/p>\n Social media influencers are promoting peptides for anti-ageing to followers. Are these products legal in Australia?<\/p>\n Currently, regulated injectable peptides fall under prescription-only<\/a> medicine categories. This means they should only be accessed through a qualified health professional for a legitimate medical indication. <\/p>\n Australian regulators have already issued fines<\/a> to companies for illegally promoting weight-loss injections directly to consumers.<\/p>\n The Therapeutic Goods Administration (TGA) lists other synthetic peptides not yet approved for human consumption, such as BPC-157, as Schedule 4<\/a> poisons. <\/p>\n To get around this, many products circulating online are sold as \u201cresearch chemicals\u201d labelled \u201cnot for human consumption\u201d.<\/p>\n Yet in practice, they are packaged, dosed and marketed in ways that clearly anticipate<\/a> human use. Online sellers typically require minimal verification of age or identity, and promise rapid shipping and high purity (for example, \u201c99%+ tested\u201d).<\/p>\n This creates a parallel market operating outside clinical oversight and regulatory safeguards. While importing or possessing prescription-only peptides without authority can lead to fines or legal penalties, enforcement is challenging<\/a> in global, digital markets. <\/p>\n At the same time, injecting appears to be becoming less taboo, particularly in the cosmetic and wellness industry. Most cosmetic injectables (including anti-wrinkle injections and dermal fillers) also involve prescription-only substances. Yet there are many clinics<\/a> that offer injections with very little oversight from prescribing doctors.<\/p>\n This broader \u201cinjectable culture\u201d, with simulataneous increases in steroid use<\/a>, may be lowering barriers to more experimental practices, including peptide use.<\/p>\n Read more: What does the evidence actually say?<\/p>\n For many peptides promoted for anti-ageing and skin health, high-quality human evidence remains limited.<\/p>\n Claims peptides such as GHK-Cu, BPC-157 and TB-500 can help regenerate and repair tissue and calm inflammation are based on a handful of laboratory studies \u2013 in cells or animals, not humans. <\/p>\n For example, there is some limited evidence GHK-Cu could play a role<\/a> in collagen production, and wound healing<\/a> in mice. But these findings have not been confirmed in humans.<\/p>\n Similarly, some research<\/a> suggests BPC-157 can promote new blood cell growth, reduce inflammation and heal tissue in rats.<\/p>\n But human evidence is extremely limited. Only three small studies<\/a> have looked at BPC-157 and these were not well designed, and lacked a control group to compare the reported effects (such as improvement in knee pain). No large clinical trials exist. So its safety and effectiveness in humans remain uncertain.<\/p>\n A consistent pattern emerges:<\/p>\n evidence is mostly limited to animal studies<\/p>\n human studies, where they exist, are small and short-term<\/p>\n there are no high-quality trials reflecting real-world use, including combinations, higher doses or long-term administration.<\/p>\n So currently, we don\u2019t have enough quality evidence to support the many anti-ageing claims made for peptides.<\/p>\n And there are risks<\/p>\n First, there is the issue of unknown product quality. Unregulated peptides may be mislabelled, contaminated or incorrectly dosed \u2013 a problem already documented<\/a> in adjacent markets, such as counterfeit steroids. <\/p>\n Second, there are biological risks. Peptides that influence growth, repair or hormonal pathways may also stimulate unintended processes. In theory, this could include promoting the growth of existing tumours<\/a> or disrupting normal endocrine function. This cancer risk is amplified by the high presence of heavy metals<\/a> in illicit enhancement drug markets. <\/p>\n Third, injecting carries its own risks \u2014 including infections, abscesses and tissue damage, particularly when products are self-administered without sterile technique<\/a>.<\/p>\n![\"Grid](\"https:\/\/www.newsbeep.com\/au\/wp-content\/uploads\/2026\/04\/file-20260407-63-haimbh.png\")
