In this Spanish‑language interview, host Antonio Torrealba talks with aesthetic/endocrine specialist Dr. Helio Galán about the booming popularity of peptide‑based therapies for weight loss, anti‑aging, hair growth and libido. The conversation begins with a lay‑person’s confusion about what peptides are, their mechanisms (small amino‑acid chains acting as cellular messengers) and the most common weight‑loss agents—GLP‑1 agonists such as semaglutide (Ozempic), GIP/GLP‑1 dual agonist tirzepatide (Mounjaro) and the newer triple‑receptor peptide retatrutide. Dr. Galán explains how these drugs signal satiety, slow gastric emptying and increase energy expenditure, and stresses that they are FDA‑approved only for specific indications (type‑2 diabetes, BMI > 27 kg/m², etc.). The duo then examines the growing wave of adverse events: “Ozempic‑face,” facial lipo‑atrophy, intestinal obstruction, metabolic emergencies, and the dangers of unregulated, low‑quality products bought online. They argue that misuse stems from social pressure, misinformation on social media, and a market that prioritises profit over patient safety. A large portion of the interview is devoted to the clinical workflow Dr. Galán follows before prescribing any peptide: comprehensive blood work (liver, kidney, thyroid, hormonal panels), physical exam, BMI assessment, and a personalized protocol. He outlines specific regimens—low‑dose retatrutide weekly, daily GHK‑Cu (the “glow” copper peptide) for skin and hair, nightly tesamorelin for visceral fat reduction, ipamorelin, MOTS‑c for energy, and PT‑141 for libido—while warning that lifestyle (diet, exercise) remains essential and that peptides are not miracle cures. The conversation also touches on broader aesthetic medicine issues: misuse of fillers and Botox by unqualified providers, resulting in severe facial deformities, and the importance of seeking qualified physicians. Dr. Galán critiques the commercialization of medicine, the proliferation of non‑FDA‑approved compounds, and the need for informed consent and ethical practice. The interview closes with a reminder to prioritize health over trends and an invitation to the audience to follow both hosts for further education.
