Disclaimers

Educational use only

All content on ModernPeptideScience is for educational and informational purposes only. It is not medical advice, not a diagnosis, and not a treatment recommendation. Reading this site does not establish any patient-clinician relationship.

No dosing or usage instructions

We describe how peptides are administered as reported in peer-reviewed studies, because that is part of characterizing the research. We do not provide protocols, "cycles," titration schedules for personal use, or sourcing guidance. Such use-oriented content is outside our scope.

Regulatory and legal status

Most peptides discussed on this site are not FDA-approved for the applications most often discussed in the peptide community. In 2023, the FDA reclassified many peptides to Category 2 of the bulk substances list, restricting compounding pharmacies' ability to produce them.

Nothing on this site should be interpreted as advice about whether it is legal for you, in your jurisdiction, to purchase or possess any peptide. Those are questions for a qualified attorney.

Safety

Many peptides have incomplete long-term safety data. Some peptides have documented serious risks (hypoglycemia with GLP-1s in certain populations; vascular/tumor concerns with systemic growth-hormone-axis stimulation; skin malignancy signals with melanotan-II). Decisions about use require a qualified healthcare professional who can evaluate your specific situation.

Editorial framing of compounds we cover

Inclusion of a peptide or compound on this site is descriptive, not a recommendation to use it. Our pages summarize what the published research shows; they do not endorse any specific vendor, compounding pharmacy, or retailer for sourcing decisions. Sourcing and access questions involve regulatory, quality, and clinical considerations that are appropriately handled with a qualified clinician familiar with your jurisdiction and situation.

Where commercial relationships exist or develop in the future (advertising, sponsorship, or other arrangements that support the site's operation), they will be disclosed transparently so readers can evaluate the editorial alongside that context.

Accuracy and corrections

We try to be accurate, but the field moves quickly and mistakes are possible. If you believe any statement on this site is incorrect, please reach out — corrections are treated seriously.
