Semaglutide is a GLP-1 receptor agonist FDA-approved for type 2 diabetes (Ozempic) and chronic weight management (Wegovy). Clinical trials demonstrate significant reductions in body weight and cardiovascular risk markers. It works by enhancing insulin secretion, suppressing glucagon, and reducing appetite.

Tirzepatide is a dual GIP/GLP-1 receptor agonist FDA-approved for type 2 diabetes (Mounjaro) and weight management (Zepbound). It has shown superior weight loss outcomes compared to semaglutide in head-to-head trials. The dual-agonist mechanism provides enhanced metabolic benefits.

Tesamorelin is an FDA-approved synthetic GHRH analog indicated for the reduction of excess abdominal fat in HIV-infected patients with lipodystrophy. It stimulates physiological growth hormone secretion and has demonstrated significant visceral adipose tissue reduction in clinical trials.

Sermorelin is a synthetic analog of the first 29 amino acids of GHRH, previously FDA-approved for growth hormone deficiency diagnosis and treatment. It stimulates natural GH production from the pituitary gland and is widely used in age-management protocols for its favorable safety profile.

PT-141 (Bremelanotide) is an FDA-approved melanocortin receptor agonist indicated for hypoactive sexual desire disorder in premenopausal women (Vyleesi). It acts on MC3 and MC4 receptors in the central nervous system to modulate sexual arousal. It is distinct from PDE5 inhibitors in its mechanism of action.

GHK-Cu is a naturally occurring tripeptide-copper complex. See the TruthTides evidence library for graded study summaries and citations.

TB-500 is a synthetic fragment of Thymosin Beta-4. See the TruthTides evidence library for graded study summaries and citations.
