Editorial Standards & Methodology
Last reviewed: June 2026
How we research, review, and verify what we publish — described honestly, not aspirationally.
How we research
Our peptide profiles are built from primary sources — peer-reviewed literature indexed on PubMed and PMC, published clinical-trial data, and FDA drug labels — rather than secondhand summaries. Each profile carries its own citations: specific claims such as mechanism, half-life, and pharmacokinetics are attributed to named studies, and every profile ends with a linked References section pointing back to the original sources.
Where the evidence is preclinical, limited, or contested, we say so plainly instead of padding the gap with personal protocols dressed up as facts.
How we verify
Every page is reviewed by the Prof. Peptide editorial team before it is published — a human read for accuracy against the cited sources, not an automated pass. The “Last reviewed” date shown on our profiles and guides is literal: it marks when a person last checked that page against the current evidence, not merely when it first went live.
How we evaluate vendors
Vendors earn a place in our vetted catalog against the same verifiable criteria: third-party laboratory testing with published Certificates of Analysis, documented purity standards, transparent shipping, responsive customer service, and a positive reputation in the research community. We describe each vendor by its own verified differentiator rather than borrowing another supplier’s credentials.
Prof. Peptide may earn affiliate commissions when you use our discount codes or buy through our links. Those affiliate relationships do not determine vendor inclusion, ranking, or verification — see our full disclaimer.
Research-use-only stance
All content on Prof. Peptide is provided for educational and research purposes only. The compounds we profile are described as research-use-only materials; nothing on this site is medical advice, diagnosis, or a treatment recommendation. We frame compounds in the context of the published research, not as products for human use.
How we keep content current
We review and update pages as new evidence emerges — new studies, FDA label changes, and regulatory shifts — rather than on a fixed calendar. Developments we consider material are tracked on our news beat, and the relevant profiles are revisited and re-dated when the underlying evidence changes.
