Guides
Peptide guides & references.
Practical, plain-English explainers — the chemistry, the terminology, the safety, and the legal picture. Educational and harm-reduction focused: no dosing protocols, no sales.
All guides 19
- Basics Peptides 101: What They Are and How to Think About Them A plain-language orientation to what peptides actually are, which ones are proven drugs, where the gray market begins, and how to weigh the evidence.
- Handling How to Reconstitute a Peptide (and Handle It Safely) A plain-English, harm-reduction guide to reconstituting lyophilized peptides: bacteriostatic water, sterile technique, the concentration math, and storage. Not dosing advice.
- Legal What "Research Use Only" Actually Means Why "research use only" and "not for human consumption" are regulatory and marketing labels — not a safety claim, and not a loophole.
- Testing How to Read a Certificate of Analysis (COA) A plain-English guide to reading a peptide Certificate of Analysis: HPLC purity, mass-spec identity, safety tests, and spotting fakes.
- Testing How to Vet a Peptide Source A practical process for judging any peptide seller: demand a batch-matched independent COA, verify it yourself, and understand what testing can and cannot tell you. Names no vendors.
- Safety The Gray Market: Sourcing, Purity, and Contamination How the research-peptide gray market works and why purity, identity, and sterility vary batch to batch — a harm-reduction reference.
- Legal Peptides and Anti-Doping: WADA Status Explained How WADA classifies peptides (S0, S2, S4), what "prohibited at all times" means, TUEs, and why many popular peptides are banned in tested sport.
- Handling Peptide Storage and Stability How peptides degrade, why lyophilized vials outlast reconstituted ones, and the storage and beyond-use principles that limit real-world stability.
- Reference Routes of Administration, Explained A conceptual, evidence-based overview of how peptides are delivered—injection, oral, intranasal, topical—and what bioavailability means.
- Reference Peptide Classes, Explained A plain-English map of the major peptide categories — GLP-1 agonists, GH secretagogues, healing peptides, melanocortins, nootropics and more — with examples and what each is claimed to do.
- Reference A Plain-English Peptide Glossary Plain-English definitions of common peptide terms, from agonist to subcutaneous, with honest safety and legal context.
- Evidence How to Read a Peptide Study Without Getting Fooled A plain-English checklist for judging peptide research — study design, endpoints, funding, and preprints — tied to our evidence grades.
- Safety How to Spot a Scam Peptide Vendor Consumer red flags for spotting scam peptide vendors: fake COAs, no batch testing, miracle claims, fake reviews, and sketchy payment.
- Regulation Are Peptides Legal? The U.S. Status in 2026 Peptide legality depends on the molecule, its intended use, and who is selling it. A plain look at FDA, DEA, and anti-doping rules in 2026.
- Science GLP-1 and Incretin Drugs, Explained A plain-language guide to the incretin hormone system, the GLP-1 drug generations, what the trials show, the known risks, and the 2025-2026 regulatory landscape.
- Science Peptide Half-Life and Pharmacokinetics, in Plain Terms What half-life really means, why native peptides clear in minutes, and how chemical modifications stretch that to days. Educational only -- no dosing.
- Science How Peptides Are Made: Synthesis, Purity, and Why Quality Varies How synthetic peptides are actually manufactured, where impurities come from, how purity is measured, and why gray-market quality is so inconsistent.
- Safety Peptide Side Effects and Safety: General Principles Why peptide safety can't be generalized, the side effects that actually show up, and the extra risks of unapproved gray-market material. Not medical advice.
- Handling Bacteriostatic Water, Sterility, and Aseptic Technique What bacteriostatic water actually is, why a preservative is not the same as sterility, and the aseptic basics that prevent the most common avoidable harms.
