Understanding Evidence Levels

Evidence levels reflect the overall quality and strength of available research for a given peptide. "High" evidence indicates multiple well-designed human trials with consistent results. "Moderate" evidence typically includes some human data alongside preclinical research. "Low" and "very low" evidence levels indicate that research is primarily preclinical or limited in scope.

Research Status Pipeline

Peptides progress through a research pipeline from preclinical studies through Phase 1, 2, and 3 clinical trials before reaching approved status. Each phase serves a different purpose: Phase 1 evaluates safety, Phase 2 tests efficacy and dosing, and Phase 3 confirms effectiveness in larger populations. Some peptides may be discontinued at any stage if results are unfavorable.

Study Types

Different study designs provide varying levels of evidence. Randomized controlled trials (RCTs) are considered the gold standard for evaluating interventions. Meta-analyses combine results from multiple studies. Cohort and observational studies provide real-world data. Preclinical and in-vitro studies form the foundation of early research.
