Dangers — Don't Do This
The watch-out section: per-compound warnings, market dangers, and the cases on record.
This is the section no seller site will copy. Every warning is attributed — to a creator’s own caution, an FDA document, the medical literature, an adverse-event report, or an enforcement case. If a danger is theoretical, the page says so. If people were hurt, the page says that too.

Cancer and Peptides: What Is Actually Known
The graded version: a real mechanism worth an open question, a wrong peptide family in the viral version, and — stated plainly — zero human data in either direction.
Go →The Setting Is the Risk: Booths, Clinics, and Missing Emergency Plans
The worst documented peptide emergencies share one feature: not the molecule, but the room it was given in — no screening, no identified product, no oxygen, no plan. RAADfest, a nursing-board anaphylaxis case, and a CDC clinic outbreak.
Go →Injection Infections: The Red Flags, Including the One That Arrives Weeks Later
The most actionable warning in the entire harm record: injection-site infections from non-sterile product and technique can surface one to several weeks later as nodules and abscesses — caused by organisms standard antibiotics often fail against.
Go →Secretagogues and Blood Sugar: The One Documented Interaction
Most peptide interactions are unstudied. This one isn't. The growth-hormone secretagogue class raises blood sugar — it's on an approved drug's label, in randomized trials, and in an FDA risk citation. The people most exposed are the ones managing glucose without monitoring.
Go →Melanotan II: The Richest Harm Record of Any Cosmetic Peptide
Priapism, kidney failure, ICU stays, and the melanoma problem nobody can count: melanotan II is the one gray-market peptide with a deep published harm file — because people have been injecting it since the 1990s.
Go →The Vial Problem: Compounded GLP-1 Dosing Errors
The largest verified hospitalization pool in the peptide file isn't contamination — it's a multidose vial, a syringe, and a measurement error. FDA's own numbers, and what they do and don't prove.
Go →Retatrutide: The Worst Record in the Gray Market
An investigational drug that legally exists only inside Eli Lilly's trials is being sold online anyway — and it owns the worst harm record in the peptide file: death reports, hospitalizations, and tripling poison-center calls.
Go →Contaminated Products & Forged Lab Reports
What else is in that vial? The fraud pattern with a court record.
Go →GHK-Cu & Copper Toxicity
Too much of the 'glow' peptide is a real toxicity — the warning comes from the creators themselves.
Go →Receptor Saturation & Desensitization
More signal stops meaning more effect — a peptide doctor's own teaching example.
