Key Research Findings
168-hour half-life achieved via albumin binding via C18 fatty diacid chain — enables once-weekly dosing in research models.
Crosses blood-brain barrier — central appetite suppression via ARC and hypothalamic GLP-1 receptors.
Demonstrated 14.9% body weight reduction in the STEP 1 trial — foundational reference data.
Reduces cardiovascular events — established in SELECT trial (2023), providing outcome data context.
Administration Reference
Subcutaneous administration is the only route studied for semaglutide in the pharmacological literature. Standard sites: abdomen (avoiding 2-inch radius around navel), outer thigh, upper arm. Weekly injection, rotating sites between administrations. Dose escalation — starting at 0.25 mg/week and increasing every 4 weeks — is the standard pharmacological approach to minimise GI effects in research subjects.

Documented Combination Protocols
Not typically combined — dual agonism study; compare efficacy differences in GIP+GLP-1 vs GLP-1 mono research.
Metabolic research stack: GLP-1 axis modulation combined with NAD+ dependent mitochondrial function.
Complementary AMPK and insulin sensitivity research across different signalling axes.
