These tools remain useful globally, but legal, cost, and provider assumptions may stay US-first while Netherlands moves through the rollout pipeline.
High-Intent Money Paths
Structured, reviewed pagesPeptide Finder
Answer 4 questions to get personalized peptide research recommendations based on your interests. Filter by category, evidence level, and preferences.
Reconstitution Calculator
Calculate reconstitution volumes and syringe units for any peptide vial. Enter your vial size, water volume, and desired dose to get exact measurements instantly.
Legal Status Checker
Check peptide legality in your state — FDA status, compounding rules, and restrictions. Select a peptide and your state for an instant legal summary.
Titration Planner
Pick a GLP-1 medication and a start date to generate a week-by-week dose escalation calendar. Color-coded by dose level with print support. Based on FDA prescribing information.
Side Effect Visualizer
Compare GLP-1 medication side effect rates against placebo with horizontal bar charts. Data from STEP, SURPASS, and SCALE clinical trials via FDA prescribing labels.
Interaction Checker
Select two peptides or medications to check known interactions. Severity-coded results (avoid, caution, monitor, likely-safe, no-data) with evidence levels and recommendations.
Cost Calculator
Compare GLP-1 medication costs: list price, insurance copay range, manufacturer discount programs, and compounded alternatives. Monthly and yearly breakdowns.
Half-Life Visualizer
See how semaglutide, tirzepatide, and liraglutide drug levels decay after each injection. Slide to any day to see the estimated concentration remaining. Based on FDA half-life data.
Vial Supply Planner
Enter your vial size, dose, and injection frequency to see how many doses you have, when the vial runs out, and exactly when to place your next order. Works for any peptide.
Cycle Planner
Generate a week-by-week injection schedule for any peptide protocol. Pick your compound, injection frequency, and on/off-cycle duration to see every injection day on a calendar.
Pet Dosing Calculator
Veterinary peptide dosing tool for dogs, cats, and horses. Select species and weight to explore peptide options, evidence levels, cautions, and extra-label regulatory guidance for veterinary use.
Doctor Export
Create a printable medication summary for your healthcare provider. Enter your current medications, doses, symptoms, and questions — then print or copy in one click. Nothing is stored.
Evidence Comparator
Side-by-side clinical evidence comparison for 2–4 peptides. Compare benefits, side effects, evidence grades, mechanisms, and PubMed references across our full database.
Sequence Analyzer
Calculate molecular weight, isoelectric point, hydropathy profile, and net charge from any amino acid sequence. Supports all 20 standard amino acids with interactive pH adjustment.
Protocol Builder
Build evidence-based peptide protocols in 4 steps. Select your health goal, choose a research-backed stack, configure cycle timing, and export for your healthcare provider. Includes safety notes and evidence grades.
AI Protocol Advisor
Describe your health goal and get an AI-generated peptide protocol with evidence grades, safety notes, and telehealth provider matching. Built on 57 peptide profiles and 25+ evidence-graded stacks. Free — no signup.
Literature Alerts
Build a personalized PubMed watchlist for peptide research. Select peptides to generate RSS feed links, direct search URLs, and clinical trial trackers for new publications.
Stack Explorer
Explore known peptide combinations with synergy rationale, evidence grades, and safety warnings. Covers healing, growth hormone, cognitive, metabolic, and longevity stacks.
Stack Generator
Select a symptom or health goal — poor sleep, ED, hair loss, anxiety, cognitive decline, and more — to discover peptides studied for that condition. Every result includes evidence grades, FDA status, and PubMed references.
Structure Predictor
Predict 3D peptide structures using Meta AI's ESMFold API. Paste any amino acid sequence and receive a PDB file for visualization. Free, no signup required.
Community Stacks
Browse and share unverified peptide stack reports from the community. Includes dosage protocols, effects, and side effects with voting. For research transparency only.
Stack Cost Calculator
Estimate monthly costs for any peptide stack. Select from research stacks, community stacks, or symptom-based recommendations. Includes 3-month and 6-month projections with insurance notes.
Interaction Matrix
Pharmacologically grounded reference for peptide-to-peptide interactions. Covers synergistic combinations, redundant mechanisms, and combinations that should be avoided. 15+ peer-reviewed entries.
Benchmark System
Evidence-based scoring for peptides, providers, and stacks across 6 dimensions. Compare options objectively with weighted scores for evidence quality, cost, safety, WADA compliance, and practicality.
Beginner Assessment
Interactive self-assessment to determine if you're ready for peptides. Evaluates your foundation (sleep, nutrition, training, stress), checks contraindications, and provides personalized guidance with conservative recommendations.
Side Effect Triage
Pharmacologically grounded triage tool for peptide side effects. Select your peptides and symptoms to receive severity-coded guidance: monitor, reduce dose, stop immediately, or seek emergency care. Includes quality vs. reaction differentiation.
COA Verifier
Interactive Certificate of Analysis verification tool. Check your peptide COA against 7 required quality standards and 8 common red flags. Get a scored assessment with actionable recommendations for independent testing.
Why Free?
Evidence-based tools should be accessible to everyone. Peptide reconstitution math and legal status information are too important to lock behind a paywall. These tools are built on publicly available data and open formulas — we believe keeping them free helps people make safer, better-informed decisions.
