Sources we use
We rely on primary sources only: FDA drug labels, approval letters, warning letters, compounding lists and advisory-committee documents; HHS notices in the Federal Register; the WADA Prohibited List; peer-reviewed studies on PubMed; trial records on ClinicalTrials.gov; PubChem; and IUPAC and NIST for atomic weights. Sellers, clinics, forums and social media are never used as sources of fact.
How calculators are checked
Every calculator uses published, standard formulas. The code is covered by automated tests that check known answers (for example, a 5 mg vial mixed with 2 mL gives 2.5 mg/mL, so 250 mcg is 0.1 mL or 10 units on a U-100 syringe; and the sequence GEPPPGKPADDAGLV gives C62H98N16O22, matching PubChem). We show the formula next to each tool so anyone can verify the result by hand.
What we will not publish
- Dosing advice, "protocols", cycles or "stacks".
- Injection instructions, or storage and mixing advice beyond what an FDA-approved label states.
- Links to, reviews of, or discount codes for sellers of any peptide, diluent or syringe.
- Claims about a peptide that we cannot support with a primary source.
- Claims we cannot support with a source.
Updates and corrections
Each page shows the date it was last updated. When the FDA, HHS or WADA changes a peptide's status, or a new human study is published, we update the affected pages and their dates. If you find an error, tell us through the contact page and we will review it and correct it.
