Dr Maurizio Viel, plastic surgeon at Cornerstone Clinic, Dubai Marina, explains everything you need to know about peptides. Peptides are short chains of amino acids that act as biological messengers, signalling cells to activate, repair, or regenerate. Unlike drugs, which block or override biological processes, peptides communicate with the body’s existing systems. They are more targeted than supplements and more precise than hormones

Unlike supplements, which mostly provide nutrients or raw materials, peptides actively instruct the body. They send targeted signals: Repair tissue, regulate inflammation, influence metabolism, stimulate collagen or affect hormone pathways. Perhaps, this precision is what renders them so attractive. “This specificity is what makes peptide therapy a clinically credible tool in regenerative and aesthetic medicine, not a trend, but a reflection of how the body naturally communicates at a cellular level”. Dr. Viel believes another reason for their popularity is that people increasingly want interventions that feel biologically aligned rather than harsh or invasive. “Patients today are also more sophisticated; they actively seek approaches that work with their biology rather than against it”.
The word ‘peptides’ sound harmless, or even natural for that matter. Yet, doctors warn that biologically active compounds are still biologically active compounds. “The risks are real and consistently underestimated”. Without a proper medical assessment, there is no safe basis for any protocol. The wrong peptide or dose can disrupt hormonal balance or suppress the body’s natural production. He emphasises: The blood tests and ongoing monitoring are essential during treatment to ensure kidney, liver and lipid markers remain stable. “Being naturally occurring does not mean risk-free, and no online community is a substitute for a physician who knows your full health history. Its important during the treatment to do regular blood tests to check if all the parameters are in the normal range and there are no issues with any organ like kidney, liver and lipid profile or over dosage of GHK-Cu.”
