Tools

• peptide_blend_calculator ~690 tokens
  Math for vials holding two or more peptides (KLOW, GLOW, BPC-157 + TB-500, CJC-1295 + Ipamorelin): units to draw and how much of each peptide one draw delivers. Name a known blend or list the components, then give the dose for one component (targetPeptide) or for the whole blend (totalDose).
• peptide_compare ~208 tokens
  Side-by-side comparison of two peptides (e.g. semaglutide vs tirzepatide, BPC-157 vs TB-500): evidence, FDA status, half-life, routes, vial sizes, storage, published dose ranges and key differences, each labelled by origin.
• peptide_lookup ~279 tokens
  For questions about one peptide: published dose ranges and protocols, reconstitution, vial sizes, side effects, storage, half-life, FDA status, stacks and community reports. Each dose row carries an origin label (clinical study, guide, community-reported, regulatory), sources and page links.
• peptide_reconstitution_calculator ~508 tokens
  Exact reconstitution math for a single-peptide vial: insulin syringe units for a dose, concentration after adding bacteriostatic water and doses per vial, or the dose held in a given number of units. Flags likely mg/mcg mix-ups against the peptide's published range. Returns a calculator link.
• peptide_search ~208 tokens
  Lists the peptides TruePeptideSource covers, matched by name, alias or topic (GLP-1, healing, weight loss, sleep). Returns names, one-line summaries, FDA status, evidence level and page links.
• peptide_supply_calculator ~506 tokens
  Plans supply and cost: how long a vial lasts, how many vials a cycle needs, and cost per dose, week and cycle when pricePerVial is given. Counts whole doses and respects how long a mixed vial keeps (from the dataset when a peptide is named).
