Pros Fully licensed and publicly traded, providing a layer of accountability Wide range of treatment categories beyond just weight loss Fast, convenient process for straightforward prescriptions Competitive pricing on many products, especially generics Discreet packaging and home delivery Available in all 50 states Cons Asynchronous consultations may feel impersonal, especially for complex treatments GLP-1 program relies on compounded medications, not brand-name drugs Limited provider continuity
The results are cumulative, and each cycle builds on the previous one, which is why we structure protocols across multiple cycles rather than expecting full transformation in 30 days
Tirzepatide works by mimicking two metabolic hormones in the body: it acts as a glucagon-like peptide-1 (GLP-1) receptor agonist and also as a glucose dependent insulinotropic polypeptide (GIP) receptor agonist

Key Points Native human GLP-1 normalizes hyperglycaemia in patients with type 2 diabetes mellitus, but the short in vivo half-life of this hormone limits its therapeutic application A number of synthetic GLP-1 receptor agonists, with half-lives between 23 h and several days, have been developed for the long-term treatment of type 2 diabetes mellitus Short-acting GLP-1 receptor agonists (such as exenatide and lixisenatide) predominantly lower postprandial glucose levels and insulin concentrations via retardation of gastric emptying Long-acting GLP-1 receptor agonists (such as albiglutide, dulaglutide, exenatide long-acting release and liraglutide) predominantly lower blood glucose levels through stimulation of insulin secretion and reduction of glucagon levels Adverse effects of GLP-1 receptor agonists include nausea, vomiting and diarrhoea, injection-site reactions, antibody formation and increased heart rate This is a preview of subscription content, access via your institution Access options Subscribe to this journal Receive 12 print issues and online access 119.00 per year only 9.92 per issue Buy this article Purchase on SpringerLink Instant access to the full article PDF
