Comparing Categories the Right Way
Compare specific substances, not categories.
"Peptides" is too broad—it includes everything from food-derived collagen to research chemicals. "Supplements" is too broad—it includes vitamins, herbs, protein powders, and more.
Better approach: Identify the exact compound and endpoint, then evaluate the evidence.
Evidence Strength Rubric
Use this simple hierarchy:
| Evidence Type | Strength | Example | |---------------|----------|---------| | Human RCTs with clear endpoints | Strongest | Creatine for strength | | Observational human evidence | Moderate | Protein timing studies | | Animal/cell studies | Weak for real-world claims | Most "breakthrough" peptide claims |
Common Comparison Mistakes
Mistake 1: Assuming "peptides" are inherently stronger than supplements
- Reality: Depends entirely on the specific compound and evidence
Mistake 2: Comparing best-case peptide claims to worst-case supplement evidence
- Reality: Both categories have strong and weak evidence depending on the specific product
Mistake 3: Ignoring safety profile differences
- Reality: Supplements generally have better-established safety data
Practical Guidance
Before adding anything to your routine:
- Identify your specific goal
- Research evidence for specific compounds (not categories)
- Consider the safety and regulatory profile
- Discuss with a healthcare provider if it's a medical intervention
