Last updated June 28, 2026 — I read this morning's peptide research and picked the items that mattered. Fresh brief tomorrow.
Featured Briefs
UNDERSTANDING CAS NUMBERS IN PEPTIDE RESEARCH
Research VialsWhat CAS registry numbers are, why they matter for peptide identification, and how to use them to verify compound identity across suppliers.
SAFETY AND EFFICACY OF SWITCHING FROM DULAGLUTIDE TO TIRZEPATIDE ACROSS CLINICALLY RELEVANT BASELINE CHARACTERISTICS IN PARTICIPANTS WITH T2D: SUBGROUP ANALYSIS OF SURPASS-SWITCH.
PubMed · BMJ open diabetes research & careViolante-Ortiz R et al., BMJ open diabetes research & care · 2026 Mar 30. PMID 41912265.
GLP-1 RECEPTOR AGONISTS AS GEROTHERAPEUTICS: NATURE AGING ASKS THE HARD QUESTION...
Nature AgingNature Aging published a pointed analysis asking whether GLP-1 receptor agonists like semaglutide are true aging therapeutics or simply effective obesity drugs. The distinction matters enormously for how regulators, clinicians, and researchers frame the next decade of longevity trials.
CELL TYPE-SPECIFIC AGING CLOCKS NOW PREDICT DISEASE ONSET BEFORE SYMPTOMS APPEAR...
Lifespan.ioResearchers used aging trajectories of individual cell types — not whole-body averages — to predict diseases including Alzheimer's and lung cancer. The approach may give clinicians a far earlier window than current biomarkers allow.

Longevity TechnologyGARM Clinic has launched what it calls the world's first Klotho longevity residency, bringing together three leading Klotho researchers. After years dominated by NAD+ and rapamycin, the longevity field may be entering a new chapter.
OURA + LILLYDIRECT: GLP-1 CARE MODEL SHIFTS TOWARD CONTINUOUS TRACKING...
Longevity TechnologyOura and LillyDirect are pairing GLP-1 therapy with continuous health tracking, signaling a shift away from the scale as the primary weight-loss metric. The collaboration reframes obesity treatment as a behavior-plus-medication journey.
