Research Tiers Explained
Every peptide in our catalogue carries a research tier badge indicating how mature the published research base is for that compound. Tiers describe research maturity only — they are not a measure of safety, efficacy, or suitability for any use.
Years of lab research behind it, some human data.
Compounds with a sustained record of laboratory investigation over several years, often including published human study data, but not approved medicines.
Backed by extensive research, including approved drug versions.
The most heavily studied compounds in the catalogue, with extensive literature and, in some cases, clinically approved pharmaceutical versions of the same molecule.
