Tesamorelin: benefits, evidence and safety
The FDA-approved peptide, examined without the anti-aging hype: its specific use in HIV lipodystrophy, clinical evidence for visceral and liver fat, safety warnings and what remains unproven.
New guide · Metabolic science
What is GLP-1?
The gut hormone behind the biggest story in metabolic medicine: how it signals appetite and blood sugar, what the large trials found, and where the open questions remain.
