Peptide Therapy

Physician-supervised peptide therapy protocols targeting anti-ageing, body composition, metabolic function and recovery, prescribed following a thorough clinical assessment and baseline blood panel to ensure appropriate peptide selection and monitoring.

Peptide therapy at Dr Tan Medical Center is a personalised, physician-supervised programme that uses short chains of amino acids — peptides — to modulate specific physiological pathways. Peptides are increasingly recognised in longevity and functional medicine for their ability to stimulate growth hormone secretion, support body composition, accelerate tissue repair, reduce inflammation and enhance metabolic function, often with a more targeted action profile and favourable safety record compared to older hormone-based approaches. The programme begins with a comprehensive clinical consultation. Dr Tan reviews the patient's health goals, current symptoms and blood test results to determine whether peptide therapy is appropriate and which peptides are best suited to the individual's needs. Common goals include improving body composition (reducing fat mass, increasing lean muscle), enhancing recovery from exercise or injury, supporting sleep quality, addressing age-related decline in growth hormone signalling, and improving energy and cognitive function. Growth hormone secretagogues such as sermorelin, ipamorelin and CJC-1295 are among the most commonly prescribed peptides in this category. These peptides work by stimulating the pituitary gland to produce more of its own growth hormone in a pulsatile, physiological pattern — in contrast to exogenous human growth hormone (HGH) injections, which suppress the body's natural GH axis. This mechanism of action makes growth hormone peptides a safer and more sustainable option for long-term use. Patients typically notice improvements in sleep quality (particularly deep sleep), body composition, skin texture and energy within six to twelve weeks of commencing a protocol. BPC-157 is a peptide with well-documented tissue-repair and anti-inflammatory properties, commonly used to accelerate recovery from musculoskeletal injuries, reduce gut inflammation and support joint health. Thymosin alpha-1 is used for immune modulation and may be relevant for patients with chronic fatigue, recurrent infections or autoimmune concerns. PT-141 (bremelanotide) addresses libido and sexual function in both men and women through central melanocortin receptor agonism, offering a non-hormonal option for patients with low desire. Peptides are typically administered as subcutaneous injections, often self-administered at home after the clinic provides instruction. Protocols are individualised in terms of dosing, timing and cycle structure. Blood tests including IGF-1, fasting glucose and other markers relevant to the chosen peptide are monitored at regular intervals to confirm response and safety. The clinic sources pharmaceutical-grade peptides and follows established dosing protocols in line with current evidence.
