Our Mission
peptides.fyi was created to serve as a comprehensive, research-focused reference for anyone seeking to understand the science behind peptides. Whether you're a student, researcher, healthcare professional, or simply curious about peptide biology, our goal is to present complex scientific information in a clear, accurate, and accessible format.
We believe that access to well-organized scientific information empowers better understanding and more informed conversations about peptide research. Each article on our site is crafted with attention to scientific accuracy, citing published peer-reviewed research whenever possible.
What We Cover
Profiles are grouped into five compound classes, and each class can be narrowed by research area:
- Peptides: Amino-acid chains studied as signaling molecules, including growth hormone secretagogues, repair peptides, melanocortins, and neuropeptides.
- GLPs: GLP-1 receptor agonists and related incretin and amylin-pathway compounds studied in metabolic research. Cagrilintide is an amylin analog, grouped here because it is studied alongside GLP-1 drugs.
- SARMs & Related: Selective androgen receptor modulators, plus non-SARM compounds commonly grouped with them (MK-677, GW-501516, SR9009, AICAR, SLU-PP-332). Each profile states the actual mechanism.
- Chemicals: Small-molecule research chemicals, including SERMs, aromatase inhibitors, PDE5 inhibitors, thyroid hormones, and dopamine agonists.
- Cofactors & Longevity: NAD+ and its precursors, glutathione, vitamins, and related metabolic cofactors.
Our Approach to Content
- Evidence-based: We reference published, peer-reviewed research. Where clinical trial data exists, we cite specific studies and their findings.
- Objective: We present research findings without making health claims or recommendations.
- Accessible: While maintaining scientific accuracy, we aim to present information in language that is understandable to a broad audience.
- Up-to-date: We regularly review and update our content as new research is published.
The science writers and research contributors behind the site are introduced on the editorial team page, and how they work is set out in our editorial standards.
