The learning path
Seven guides in rough order of need — what the research actually says, how stacks work, where to buy, what it costs, and how to stay safe along the way.
How to Research Peptides
Read a PubMed study, understand our reliability tiers, and spot weak or biased sources.

How Stacks Work
Why people combine peptides, common stacks, and where synergy and risk actually sit.

How to Source Safely
Where to buy, the vendor-vetting checklist, red flags, and how affiliate links work here.
Read →"FDA-Registered" ≠ "FDA-Approved"
Scam Series #9: the regulatory vocabulary sellers blur, the court case that shows why it matters, and a 2-minute check.

What Does Peptide Therapy Cost?
No single number — the five factors that set the price, GLP-1 titration, and why the cheapest vial is rarely cheapest.
Read →Safety & Side Effects
Known side effects, contraindications, what to avoid, and when to talk to a doctor.

Storage & Reconstitution
Lyophilized vs mixed shelf life, fridge temperatures, bacteriostatic water, and the signs a vial has gone off.

Glossary
Plain-English definitions for 130+ terms: subcutaneous, half-life, agonist, COA, HbA1c, NF-κB, preclinical, and more.

Calculators & tools
The numbers around a protocol — dosing math, unit conversions, half-lives, and the published titration schedules. Every tool runs in your browser; nothing is stored.
Reconstitution Calculator
Vial amount + bacteriostatic water → concentration, mL per dose, and the exact mark on an insulin syringe — with a quick-reference table and step-by-step mixing guide.
Open the calculator →Mix Checker (NPC/Purity)
Reconstitution draw with CoA purity adjustment. Enter NPC from your Certificate of Analysis to get the corrected syringe units.
Open the checker →Unit Converter (mcg/mg/IU)
Convert between mcg, mg, and IU for common peptides. Includes a concentration calculator for reconstitution math.
Open the converter →Half-Life Calculator
Enter a half-life + elapsed time → % of the molecule remaining and a 5 half-life washout table. Pure pharmacokinetic arithmetic.
Open the calculator →GLP-1 Titration Timeline
The published STEP (semaglutide) and SURMOUNT (tirzepatide) titration schedules rendered week by week. Display of trial protocols only.
View the timeline →Peptide Match
Two questions about your research goals → a ranked shortlist, each with its research status and sourced-study count. Runs entirely in your browser — nothing stored.

The Peptide Literacy Series
Nine short articles, one mental tool each. By the end you can pick up any peptide routine, product page, or forum post and spot what’s missing — without anyone telling you. No prior background required.
The Same Name, Two Different Drugs
Why a peptide's name often fails to identify the molecule — and the three questions that reveal which you actually have.
