- Workbook / Coverage
- All 32 unique profiles linked from the peptide directory; includes non-peptide compounds listed by the site.
- Workbook / Peptides
- One row per profile. Categories, goals, experience level, dosage, half-life, price tier, administration, and benefit topics are the website's entries.
- Workbook / Protocols
- Structured dosage tables transcribed from each profile. Values remain text to preserve ranges, units, and qualifications.
- Workbook / Pairings
- Compounds linked in the stacking section and Often Paired With sidebar; section labels distinguish these lists.
- Workbook / References
- Study titles and links as cited by each profile; references have not been independently validated.
- Workbook / Sections and Related Links
- Direct links to narrative sections (including mechanisms, safety, and FAQs), articles, and tools.
- Workbook / Scope
- Structured data extraction, not a full-text copy of the website. Long descriptions, protocol commentary, FAQ answers, and safety narratives are available through the source links.
- Workbook / Interpretation
- This workbook records what the website states. Clinical claims, dosages, safety, and approval status were not independently checked; these entries are not treatment recommendations.
- Workbook / Missing values
- A blank cell means the requested field was not found in the profile.
- Workbook / Price tiers
- Symbols and tiers are relative labels used by the website, not actual product prices.
