Peptide Claims & Misinformation Hub
A catalogue of the most common claims made about peptides in marketing, social media, and grey-market sources — and what the evidence actually supports. Use this hub to interpret claims you encounter elsewhere.
Marketing red flags
‘Clinically proven’ without citation, before/after photos, celebrity claims, exaggerated synergy — and what each one usually conceals.
Fake citation tactics
Misquoting studies, citing unrelated peptides, presenting animal data as human, and other patterns to look for.
Synergy: assumed vs demonstrated
The difference between additive and synergistic effects, and why most stack-synergy claims do not meet the bar.
Stacks without direct human evidence
Most peptide combinations have not been directly tested in humans — and this is rarely disclosed in marketing.
