Compare peptides side-by-side
Head-to-head peptide comparisons built from real data: an overlaid effect-profile radar, a strength-of-evidence grade, mechanism & half-life, study volume, and a goal-by-goal breakdown. Pick a popular matchup below, browse by compound class, or build your own.
What each comparison shows
Effect-profile radar
Community effect scores across seven outcome areas, overlaid on one chart.
Strength of evidence
A Clinical / Human / Preclinical / Emerging grade from the actual studies indexed.
Mechanism & half-life
Receptor target, route, and pharmacokinetics where they're established.
Study volume
How many approved studies back each compound — updated daily by the Librarian.
Goal fit
Which compound leads for weight loss, muscle, healing, and more.
Most-searched comparisons
GLP-1 & weight loss
Incretin agonists compared for metabolic and weight outcomes — the most-searched peptide matchups.
Growth-hormone secretagogues
GHRH analogs and ghrelin-receptor agonists compared for GH release, body composition, and half-life.
Healing & tissue repair
Regenerative and cytoprotective peptides compared for recovery, joints, and soft-tissue repair.
Nootropics & cognition
Neuroactive peptides compared for focus, mood, and neuroprotection.
Longevity, metabolic & other
Mitochondrial, longevity, and specialty peptides compared across the rest of the library.
