From weight loss clinics and anti-ageing treatments to gym culture and wellness influencers, peptides have become one of the biggest health trends of 2026. Promoted for everything from muscle recovery and better sleep to healthier skin and longevity, these treatments are attracting growing interest from South Africans looking to improve their wellbeing.
But as demand increases, so do concerns about safety, regulation and misinformation.
Industry experts are now urging consumers to look beyond the marketing before investing in peptide-based treatments.
Why Are Peptides Suddenly So Popular?
“Not a week goes by without hearing about someone who is getting into peptides or wants to start selling them,” says Toni Carroll, founder of South African nutricosmetics brand My Beauty Luv.
“I would never discourage entrepreneurship, but massive alarm bells have been going off for me.”
Carroll says the rapid rise in injectable peptide products, many sold through informal channels, is particularly concerning.
“When something is this powerful and people are injecting it into their bodies, we need far more regulation and consumer education.”
What Are Peptides?
Peptides are short chains of amino acids that naturally occur in the body and help regulate important biological functions, including:
- Metabolism
- Appetite
- Hormone release
- Tissue repair
- Inflammation
- Immune function
Some well-known medicines, including insulin and GLP-1 receptor agonists, are peptide-based or mimic naturally occurring peptides.
However, many newer products being marketed for weight management, athletic performance and longevity remain experimental.
The Science Shows Promise — But Caution Is Needed
Steve Uria, CEO of physician-led longevity clinic WellNest Gold, believes peptide medicine has enormous potential.
“The science is exciting, particularly when it comes to targeting specific biological pathways,” he explains.
“However, consumer interest has moved faster than the evidence, regulation and public understanding. Many peptides currently being marketed for longevity or performance remain experimental.”
Not Every Peptide Product Is the Same
One of the biggest misconceptions is that all peptide products are manufactured to the same standard.
According to Uria, two products carrying the same peptide name can differ significantly in:
- Purity
- Sterility
- Stability
- Dose accuracy
- Active ingredient concentration
He warns that terms such as “pharmaceutical grade”, “laboratory tested” and “research grade” are frequently used in marketing but don’t necessarily guarantee quality or safety.
Consumers should ensure injectable peptide products are manufactured in licensed facilities that comply with recognised pharmaceutical Good Manufacturing Practice standards.
Proper storage is equally important, as peptides can degrade when exposed to heat, moisture or light.
What Does South African Law Say?
In South Africa, registered peptide medicines must be approved by the South African Health Products Regulatory Authority (SAHPRA) and supplied through licensed healthcare professionals and pharmacies.
Although some unregistered medicines may be accessed through Section 21 authorisation for individual patients, this does not allow widespread commercial sale.
In May 2026, SAHPRA issued a warning about unregistered peptide products that had not been approved for safety, quality or effectiveness.
“A recommendation from a healthcare professional does not automatically mean the product itself is SAHPRA-registered,” says Uria.
Warning Signs Consumers Shouldn’t Ignore
Experts recommend avoiding peptide products that:
- Are sold through social media or informal online sellers
- Are offered without proper medical consultation
- Promise guaranteed or dramatic results
- Claim to reverse ageing
- Are labelled “For Research Use Only”
- Have no identifiable manufacturer or batch number
- Cannot provide traceable quality documentation
The Future of Peptide Medicine
Despite concerns surrounding today’s marketplace, experts remain optimistic about the future of peptide medicine.
“The future isn’t simply about having more peptides,” says Uria.
“It’s about more precise medicine built on credible evidence, pharmaceutical quality, lawful access and responsible medical supervision — not hype.”
For consumers, the message is straightforward: before considering any peptide treatment, ask questions, verify the product’s origin and ensure you’re receiving medical advice from a qualified healthcare professional.
