Selank vs Orforglipron

Side-by-side comparison of key properties, dosing, and research.

Cognitive Enhancement
Selank
GLP-1 / Weight Loss Agonists
Orforglipron
Summary
Selank is a synthetic heptapeptide analog of tuftsin developed in Russia. It is a potent anxiolytic that reduces anxiety and enhances cognitive function without sedation or addiction. It is approved for clinical use in Russia for anxiety disorders.
Orforglipron is an oral, once-daily small-molecule GLP-1 receptor agonist developed by Eli Lilly. Unlike injectable GLP-1 peptides, it is a non-peptide compound absorbed orally without food restrictions, representing a major convenience advancement. Phase 2 trials showed up to 9.4% weight loss at 36 weeks, and Phase 3 trials (ATTAIN program) are ongoing for obesity and type 2 diabetes.
