Tools

• blend_concentrations ~368 tokens
  For several components dissolved together in one volume: each component's concentration and its share of the blend by amount. Arithmetic only; it says nothing about whether components can or should be combined.
• compare_peptides ~345 tokens
  Side-by-side research comparison of 2-3 peptides on structured profile fields: mechanism and targets, research areas, evidence level and human-trial availability, safety and side effects, FDA/WADA status, half-life and studied routes, with references. Each row says whether the values are the same, d
• convert_units ~292 tokens
  Convert an amount between mg and mcg exactly. IU ↔ mass conversion only works with a peptide whose profile documents an IU-per-mg factor (pass `peptide`); otherwise the result is an iu_factor_missing issue, never an assumed factor. Pure arithmetic: not a dosing recommendation.
• cost_per_amount ~471 tokens
  Price arithmetic for a purchase: total cost (price plus optional shipping) and cost per mg, per mcg and (with a peptide's documented factor) per IU. Uses only the numbers given; it never estimates prices or shipping and converts no currencies.
• get_peptide_categories ~116 tokens
  List the Peptide Library research categories (e.g. GLP-1/Metabolic, Cognitive, Longevity) with a description, the number of profiles and every profile in each, with links. Use a category id with search_peptides to filter.
• get_peptide_details ~253 tokens
  Full educational research profile for one peptide: classification, mechanism and targets, research areas, evidence by tier (regulatory label, controlled human trials, other human studies, secondary reports, animal and in-vitro research) with cited sources, safety and side effects, regulatory status
• get_research_trends ~145 tokens
  This week's most-researched peptides in the Peptide Library community (Trending Now, last 7 days): rank, share of researchers and growth as percentages, with what moved. Aggregate and privacy-preserving: no head counts, no individual activity, small cohorts suppressed. Popularity is not evidence of
• search_peptides ~398 tokens
  Search the Peptide Library research database by name, synonym or alias (fuzzy), optionally filtered by research category or research area. Returns short educational profiles with evidence level and the canonical Peptide Library URL. Use get_peptide_details for the full profile. No dosing information
• search_research ~310 tokens
  Search Peptide Library's own educational content: the site FAQ, per-peptide FAQs, published articles and free courses. Returns titles, short snippets and links with source attribution (no full text, no third-party articles). Dosing, reconstitution and injection guides, and content about buying, vend
• solution_concentration ~302 tokens
  Concentration of an amount dissolved in a volume of liquid (amount ÷ volume), as mg/mL, mcg/mL and, with a peptide's documented factor, IU/mL. Pure arithmetic on the given numbers: it does not suggest amounts, volumes or how to prepare anything.
